First off this US Post Office is inside MCAS Miramar, if you don't have proper ID you cannot enter the base.
I came here midday to drop off a package already postage paid. The lady was very nice and greeted me. She gave me a receipt for it and printed the tracking number for me. It was a quick in and out process. The building was cleaning and the parking was ample outside. I have zero complaints (a rarity for a postal visit).
It's a bit hard to find the first time. It's across from McDonalds on the NW side. read more
