How to Address US Mail


Address Placement

Complete addresses with telephone numbers are very important. Postal Services requests that forms be complete to be certain the material is delivered. Post Office box numbers or rural routes are unacceptable addresses for courier, messenger or specialized delivery services.

All mail needs a delivery address and must also have a return address. The following information is recommended in the sequence and position indicated for addressing:

Domestic Address Format

Sender's Name
Sender's Address (Mail Stop Code)
Sender's City, State & ZIP + 4 Code


                                      Recipient's Name
                                      Recipient's Address (Mail Stop Code)
                                      Recipient's City, State & ZIP + 4 Code


International Address Format

Sender's Name
Sender's Address (Mail Stop Code)
Sender's City, State & ZIP + 4 Code


                                      Recipient's Name
                                      Recipient's Address (Mail Stop Code)
                                      Recipient's City, State & ZIP + 4 Code
                                      Country Name (Spell in English)
You will get the best possible service if you:

123 W MAIN ST APT 400
OR
P O BOX 125
BUT NOT BOTH


Envelopes

Placement of the address on the face of an envelope should conform to USPS specifications.

Labels

Labels for use on parcels, packages or large envelopes must be addressed according to the recommended format. The address must be complete. Improperly prepared labels will be returned to you for correction and/or completion. Labels that are applied must be parallel to the bottom edge of the envelope to be processed by the USPS on automation equipment.
