The method of transportation in and near Supai AZ is mule, horse, helicopter, or walk. UPS, Federal Express, DHL etc. do not deliver to this remote area. Only the United States Post Office services Supai by using "Mule Train Mail".
Tourists love to visit Supai AZ because of the historic Indian Reservation, scenic hiking trails, picturesque waterfalls, etc. And of course it is cool to send postcards to family and friends postmarked with the special "Mule Train Mail" postmark from the only remaining USPS post office that still uses "Mule Train Mail" service.
People outside of Supai AZ who enjoy sending mail to family and friends with special or unique postmarks can also have cards and letters postmarked with the special "Mule Train Mail" postmark without traveling all the way to Supai. All anyone has to do is place their ALREADY STAMPED cards and letters in a box or large envelope and enclose a note to the Supai Postmaster requesting the Supai postmark service.
Simply mail the box or large envelope containing the already stamped cards and letters to:
Supai Arizona Postmaster
US Post Office

Supai, AZ 86435
The USPS postmaster in Supai will postmark each of the already stamped envelopes with the "Mule Train Mail" postmark and send each card or letter to the intended recipient. This is a terrific service which does not require actually making the challenging trip to Supai.
To use this really great service I recommend mailing your boxes or large envelopes 10 to 14 business days in advance of when you want the enclosed stamped cards or letters to arrive, because mule delivery service takes longer than the typical mail service. read more
