I went to my local Walnut, CA. Post office yesterday to mail out a belated set of Christmas gifts for a fellow Yelp Elite friend. To my pleasant surprise, there was a short line, but it gracefully moved along quickly so to me that was equivalent to no line. Once again I don't like writing lower-star reviews but a certain staff member was extremely unprofessional. That said, I'm agreeing with some other reviewers' comments that the staff here Need to display proper work ethic at least NOT yawning close to 445pm, PST. Seriously?! I thought that was super unprofessional although the staff was half answering my questions, still witnessed her yawning at least cover her mouth?! Wow. That's so disrespectful and rude to a fellow Walnut resident. I was going to rate them 5 stars for their efficiency but this staff person just ruined it all. SMH! read more

This month (September, 2026), I have over 5 late package arrivals using this post office. It is in your best interest to NOT use this location. Furthermore, I have personally seen this post office casually throwing packages from their counter into the baskets without any care for the contents while the baskets are 2-3 feet from them speaking towards their laziness in handling of your shipments. It is pathetic and unnerving to say the least. Then there is their handling of assisting customers which is severely painful filled with negativity on every single matter I have witnessed or had the displeasure of enduring. Office manager also complains about people coming in just before closing to mail packages to her patrons. It would appear working an extra 5-10 minutes BEFORE CLOSING to support customers apparently will not be tolerated at this location. I also must ask, who in the world complains in front of their patrons?!?!? Use anywhere BUT this place to save yourself the hassle of poor service and an almost guaranteed late delivery on your mailings. read more

The supervisor is very helpful and kind, she responds to clients' concerns and questions promptly. The people under her can be unprofessional and rude sometimes, however, she will take appropriate steps and actions accordingly. Not the most customer friendly staff at the window, so you are pretty much at their mercy and remember to remain polite. read more

Going into the office service is ok, but they never answer their phone if I need to call them. Very poor service! They should be required to answer their phone or provide an answer service to leave messages. read more

Last I checked this was the walnut post office and not the ghettolandia one so why is the service so terrible? The lady who works here is SO rude and horrible. How people like this get hired and stay here is beyond me. Rude and horrible behavior to a young woman who was here late and needed help understanding how to ship an international package. read more

Asian lady in front actively ignores other asians and calls out to certain people she prefers to help in line. "Hey you in the white you're next." She also is very rude to certain people and switches up in the next second. Never smiles and is always angry looking. Waited 35+ minutes in the line obviously dropping something off and she stared at us and ignored us. Someone from the back came out and explained we could simply leave it after scanning a QR. read more

DO.NOT.COME.TO.THIS.USPS. The rudest customer service ever. The line was out the door, with only one person working the counter, and even she was clueless. She kept asking the "manager" for help. The manager? She was at the self service kiosk helping others. It's self service, why are you there? Not to mention, you can hear her obnoxious, loud voice from a mile away. She's literally shouting and also talking smack on her fellow workers. "It's so short staffed today. If it were up to me, I'd fire everyone for calling in sick. It's that kind of day. I'm over it." And never mind trying to send a package without the entire post office knowing what's in the package. "You're mailing a expensive watch??!!!!" Her voice echoes across the room. Never coming to this USPS again. I never leave a one star review, but this place is awful. Avoid at all costs. read more

Plenty of parking at 3pm on a Wednesday afternoon. The lines were also not that packed. The customer service, however, could be improved on. The person who helped me didn't seem like she enjoyed being there. A smile and some basic friendliness would be nice. read more

The old Asian lady in the left side is very rude and unpleasant she tossed me my package when I realized it was $30 to ship it and said " do you want to pay or not" and the manager or supervisor Juanita lets her get away with being disrespectful to customers.Honestly there all very unprofessional there , talking about other co workers , gossiping , basically anything but there job. read more

If I could give zero stars I would. The lady with short hair at the front desk was rude to myself and rudely said to the customer in front of me "in YOUR country it is different and you need to learn it OUR way here". I live less than a block away from here and will refuse to do my business here. She did not see friendly and would recommend for others to use another postal service. read more

Thought I'd give an update to this. Tracking is much better overall now when scanning in and dropping off packages.

This has been bothering me since earlier today. This poor girl got yelled at in front of everyone that was in line. She went up to the manager and asked if she can get her letter that she accidentally put without a stamp.. The manager yelled at her saying "why ,why would you do that what were you thinking, why . I can t get that for you do you see this line! Then she yells at the staff in the front to get hlep. The poor girl looked shocked ! Like damn we all make mistakes. And when the girl left the managers says that she is stressed and had a bad day. Like what! Thats No an excuse, whats so ever. Your supposed to be the example for your staff and if this job is so stressful for you then maybe this job isn't for you! Horrible customer service and very disrespectful. I hope a hire up does see this and does something because looking at the reviews its not the first time someone has complained about her. You really dont know what someone is going through in life and for you to just belittle her and yell was just horrific, your lucky you did not get the wrong girl because things could have been ugly in there. read more

Uh, come here if you want to be abused Literally the Asian lady is super rude and disrespectful. Just expect her to be rude and you should be all set. Don't know why but someone seems to have ***** in her sandwich Every Day. I frequent this location and her face is not pleasant either. Must be her second time around menopause. You will know who i am talking about. read more

The staff here are very rude and unhelpful. I've had several instances of bringing in packages and getting yelled at by the staff to take it around to the back (which means getting back into my car and driving around to the back of the building) and once I take it to the back, I get yelled at by the workers there because they also don't want to handle my packages. Seems no one is interested in actually working. I've also left packages in their drop box and had workers slam the door open next to the Dropbox and yell at me for putting my packages there. The anger amongst staff at this location is on another level. Hopefully they get some anger management training soon! read more

There is an Asian female employee at this post office who treats fellow Asians with discrimination. When dealing with Asian customers, she wears a hostile and disdainful expression, but when interacting with non-Asians, she is all smiles. Please review the surveillance footage to verify this statement. I have been to this post office multiple times and have observed this employee on several occasions. The other employees do not behave this way. What's even more infuriating is that their manager seems completely unaware of the situation and simply assumes that customers are unfairly targeting this Asian employee. I should really show them the reviews this post office has on Yelp--I will also be giving them the lowest rating. read more

Came here to sent package and the staff is really helpful. Lan is the one who told me to sent out my package with cheaper options. When I was in line, I also saw her very patiently explaining to elderly lady who is having some issues with her mail. The facility of this location also great because they have 24 hours drop-off package and also has self-serve kiosk with scale. read more

IF YOU ARE DOING YOUR DRIVEWAY AND NEED TO PUT A HOLD ON YOUR MAIL, DO NOT DO IT IN PERSON, DO IT ONLINE """""" They should have people skills here ! No one does . People at this post office are lazy !!! I could not understand why they only had 2.5 stars but now I do, So our driveway was being done and because of that we were forced to park our cars outside. We have a mailbox that is probably a foot away from our entrance door and we also did stairs that lead to that mail box starting from the sidewalk which is about 32 ft long X almost 7 ft wide . On June 7th our contractor adviced to us not to step on the cement while it dried cause that was the day it got poured, so I decided to head to the post office off of lemon street and put a hold to our mail because I couldn't do it online on that day. On thursday june 12, 2025 after talking to the contractor he said we could step on it, I went and picked up my mail and release the hold for them to deliver my mail after that. However we still couldn't drive on our cement being that it got poured on June 7th and we were told to wait at least 2 to 3 weeks to drive on it. I left my car parked outside, who knew to the surpirse I was going to get a sweeper ticket, I honestly could not believe I got a ticket being that my driveway had 4 orange cones at the edge of the driveway by the sidewalk to signal anyone they could not come into our driweway. I needed to submit paperwork to the city to appeal the ticket so I called the post office to have additional paperwork but apparently after you pick up your mail paperwork you submit in person gets tossed out the day you pick up your mail. Anyways so when I tried to explain this to the supervisor #Juanita, she try to twist my words around and laughed and said "imagine if we kept paperwork of all the hold mail " ? and she said it was my fault for parking on the street, and that one thing had nothing to do with the other when in fact it did, it did because I literally had to put a hold mail for Ivan ( out mail delivery guy ) not to step on the wet cement that leads to the mail bo and no could walk or drive on driveway, Yes it was probably my fault but they should have had some kind of record that I held our mail at that post office for a while, it should be logged into a computer or something just as if it was done online.!! What if this was a different scenario where there was a more delicate situation and had to prove my mail was held at a post office and got put in jail or something else because I did not have writen proof I wasn't home or something like that ?? Card for hold request should either be sent via mail to us or better yet given to the customer for proof on the day of hold release for proof !! ( then it will be up to the customer whether they want to keep it or toss it out) . That way we don't have do deal with people who don't have customer service skills !!!!!. read more

The phone operator is very very very rude. I was not able to reschedule a redelivery on the USPS website, and thought my local postal office could help me, but the operator kept saying "everyone else can, why can't you?". Well, that is the reason I call my local postal office. She then put me on hold without even telling me that she will put me on hold. how rude. read more

I just left this post office with a pair of sunglasses that I purchased and I was trying to return along with the provided return shipping label. It's unbelievable to wait in a long ass line to have a rude lady behind the counter tell me that I need to purchase packaging tape in order to wrap the return label around the small box instead of her doing it herself. Like seriously? The tape was right in front of her! This post office is so ghetto and I honestly can't believe that this is our post office here in the city of Walnut, where my family and I live in! What happened to customer service? Super disappointed with their horrible service! read more

Somehow this place is always having an equipment shortage and is not accepting packages.. That's literally what you're here for?? Also it has happened multiple times now that an order I'm waiting for is delayed because after it arrives at this facility, in the city where I live, instead of sending it out for delivery they for some reason ship it to Chino.. which adds a few days onto my expedited delivery date. How does that make any sense whatsoever?? This place needs to get it together or shut down. Literally such a pointless place. read more

The worst USPS office I ever been to especially the older Asian lady she's very rude and she missed treat the packages

Laziest post office employees I've ever encountered , the overall review here on yelp sums it up - they did not want to give me receipts for my packages, unless I scan it myself - I can understand if there was a long line , there was nobody there. The manager's attitude says it all "if you don't like it here, go somewhere else" , well, how about you go somewhere else because this is my city, I will keep coming back to make sure you guys do your jobs The older Asian dude in the pic will mouth off , and somehow this is ok to the manager, who supports this type of behavior - walnut can do better than these two clowns It is important to note that there are some good employees at this branch, these 2 are exceptions read more

A package I bought from a TikTok vendor has been there for around 20 days. It was a gift for someone. Oh, we'll... . .

Their driver kept on delivering wrong regardless of what the label say. I'm had it with this damn company!

The manager of this office is rude shaming people. Unhelpful. The mail sorters have stolen my gift cards 2 times. If you have package to large for box there should be a yellow card in P.O BOX so you can ask for your package. At the counter. The counter girls are great read more

Sent package lan was very pleasant and knowledgeable. A pleasure to meet with always caring and efficient

This Walnut USPS branch has the worst customer service ever. I talked to few customers and they all agreed and mentioned there is one Asian old lady with above shoulder length hair, usually sits on the first left counter as customers enter the building. She always has the bad customer service and not polite. I experienced before and unfortunately I experienced again today. This lady never greeted customers. I handed my package and asked for receipt and said "Thank you". But she does not know how to smile. And It made me pissed off was as she handed me the receipt. She did not extended her arm to hand it to me. I need to get extend my arm all the way to her seating spot to grab it. Hello, if you really hate your job, just let someone to take over. I don't want to walk in the office and get upset just because I need to drop off the package and receive this treatment. West covina branch is 300% better than walnut branch. I visited few other branches including city of industry, Pomona, 2 West Covina location, and Monterey Park. Other branches are all fine, only Walnut hired all these not professional staffs to serve the customers. This Asian old lady needs to retrain her customer service or just send her to the back and work on something else. No customers deserve this type of service. I would rather drive further to different branch and not coming back to this location again. Please take this feedback seriously and talk to your problem staff. read more

the worst post office in socal! the workers don't know what to do, give attitude, get the big boss Juanita and she rolls out and doesn't know the policy's of her own post office! I will be tracking my package very carefully as I believe the worker that took it threw it away! Juanita THE SUPERVISOR mentioned to me that talking to me "was like talking to a wall". See other reviews on google as well! so accurate! she really is "oscar the grouch" here. poorly run, and terrible customer service. This post office may be closed soon. read more

Absolute joke of an establishment. I spent an entire hour trying to get ahold of someone at the local station where my package is being held. Granted I was 1 digit off when entering the shipping address, I'm now out $150 and have to go to the ER to get the medication I had delivered from an online mental health service. Had someone answered I was told by the 800 number that they would be able to hold it or redeliver it. The minute I saw it wasn't delivered due to my error the site said it would be returned to sender immediately. The 800 number agents (multiple) said this shouldn't be a problem at all and opened a support case - which takes 1-3 DAYS. What good is that if it's being sent back to the sender (who does not do refunds, mind you) tomorrow morning? The DMV would have better customer service even if the building was on fire compared to this location. read more

US Post Office - 48 calls from 4-5pm. Trying to simply request an item to be held. Are you guys really open until 5pm? Doesn't seem like it - Post Offices Near Me - Walnut, California

Juanita is one of the worst employees I've ever had the misfortune of interacting with. I specifically pretended I didn't have debit to avoid her. First when we came in she has an extremely loud and domineering voice and tried to shame an elderly man for asking for tape, saying loudly "I don't know why people don't come prepared." He stood there for about 4-5 mins before she asked the other employee at the desk for some tape. Then she was explaining that she misspelled something but reassured the customer loudly that it was okay that she misspelled something. The last thing she did in this span of about 6 mins by the way was say "It's one of those days" after someone politely asked her how she was doing. LOOK AT ALL THE OTHER REVIEWS THAT MENTION JUANITA. read more

While waiting to be assisted in line at around 12:30 PM today at this post office a worker with the name of Juanita came in to the main area from a side door. She asked in a fairly loud, rude voice if anyone was waiting to perform a transaction payable with a credit card or debit card. No one responded because she was not in uniform and did not introduce herself. Juanita restated her question stating "Really?! No one has a transaction that can be paid with a debit or credit card?" Eventually one lady did step forward, and Juanita responded "Finally! We have someone who is smart!" In making such a rude statement, she was basically stating that the rest of us were not smart. To be honest, this postal worker was mean, nasty, and condescending. I caught her name from our excellent service agent, Han, who was asking for her a couple of questions in order to assist a coworker. I was actually grateful that I was not the recipient of Juanita's rude service, because by the time we were finished with our service agent, who did a great job, the first person that Juanita bumbling in helping was still having to deal with her I'm not saying that I will never go back to that post office, but the one star rating is not a reflection of the other fine US Postal Service workers at that location. However, if I ever have to wait in line and Juanita comes out of the side door, offering her service I will never accept her offer. read more

One of the cleanest post offices I've been to with great services and ample parking. While waiting in line, a person named Deborah approaches the line asking people if they had packages to drop off. She helped me with my package. We went to a machine and it was charging me a higher price. Crazeee machines. I've always preferred the personal touch. Then Deborah took me to the counter where Janet was and Janet was so cheerful and efficient and was able to get me a lower price. I could see that all the employees have a genuine cheerful attitude and smile and happy work environment. read more

It's the main USPS office I go to when I'm in the area, and have been going there for years. They are like any other USPS, and are super-busy during the holiday seasons, but they seem to get ample supply of whatever you may need (e.g., packaging supplies) pretty quickly. The customer service has been okay. I've had both good and not-amazing experiences, but the tasks mostly get taken care of. I had to come by to deal with an issue with holding mail because of my mom's health, but the post office employee refused to provide the my mom's mail to me unless I have a written approval from my mom. Apparently, no other paperwork will work. So, if my mom is completely unable to speak/write at this time, and physically incapable of going to the post office, they're just going to hold the mail forever? Or what about forging a letter; would they even know the difference? This particular experience rubbed me the wrong way, but the employee didn't care and didn't want to deal with me. I'll come by whenever I absolutely have to. Otherwise, heading to other USPS offices and postal annexes. read more

Tried to call them in the early morning for more than 30 minutes, guess what Not even ghost would pick it up! Horrible!

As someone that has been going to this post office for the past 25 years for business, I don't have much good things to say about this place. To start, they allow business account holders to drop off packages in the dock area in the back, but you can bet that none of the parking spaces marked for "customers" are available, ever. Why? because they want to make it as unpleasant as possible so you don't drop off your packages in the back, so less work for them. There's always an employee vehicle parked there, or mail truck parked in the customer's spot. A few months back I complained about it, and guess what? after they repaved the back area they completely took out the few customer's parking spot and so now we have zero parking in the back (So don't blame us for parking all over the place in the back) The freight truck drivers are also very rude and make sure that you are well aware that you are in their way with their honking (the black guy looks like he can't hate his job any more than possible, and the European looking bald guy always drives his truck fast and furious in the back parking lot) They usually close the dock on busy days (like after a black friday weekend) because they can't handle the amount of drop offs and make you drive 7+ miles away to another hub to drop it off. They also DO NOT scan the packages to update tracking information. This causes a lot of headaches for the businesses as we constantly get customers asking why we haven't ship their packages yet as it looks like from the tracking information the package is still in our hands. The front counter is no different, everyone there works at a snails pace because hey, why hurry? it's not like they get paid any more for doing a better job or get paid any less for doing a mediocre job. It seems like the work culture there, to be as mediocre as possible with the least amount of effort possible. There's only two guys in the back that's at least reasonable and friendly and two Latina lady that are nice, everyone else looks like you are wasting their time if you even begin asking a question. And boy are they extra mean to Asians who can't speak English properly, instead of trying their best to help, they just act annoyed and pretend they can't understand. Bottom line, don't go there. I only go because I don't feel like driving 7 miles to the other location, but if this keeps up, I just might have to. read more

The worse customer service. I tried to drop off my package today with pre printed label and I was inquiring if the barcode would scanned since it looks like my printer prints hazy picture. And the staff Yolanda, gave me unprofessional and condenscending treatment from the initial reply, "well whatever you drop off, we take, you fix your computer its not my problem. I cant reprint it" When i had the same worry last year, they would just double check with their scanner or just gave me instruction if it wont work and i had to reprint it. And I replied I dont mind reprint it, but the way she said it is pretty unprofessional and rude. And she just shrugged her shoulder. The post office in West Covina closed down, and only this one and South Hills the closest to me, and I feel for the close down, but hey, I don't take it to my work when I had a bad day! read more
