Addressing Envelopes and Packages

When addressing write the address parallel to the longest edge of the envelope.

The address you are mailing to should be written as follows:

  • Recipient’s name
  • Business’s name (if applicable)
  • Street address (with apartment or suite number)
  • City, State and ZIP code (on the same line)*
  • Country*

*(for letters or packages going outside the USA, contact the Mail Center staff for any questions on address formatting for mailing internationally)

The return address should be written in the upper left-hand corner of the envelope.

  • The return address is not a requirement on all types of mail. However, omitting a return address prevents the USPS from returning the item to you if it is undeliverable. (examples damage, postage due, or an incorrect address)
  • Some classes or types of mail do require a valid return address.

The stamp or postage is placed in the upper right-hand corner of the envelope.


When addressing write the address on the largest face and parallel to the longest edge of the package.

The address you are shipping to should be written as follows:

  • Recipient’s name
  • Business’s name (if applicable)
  • Street address (with apartment or suite number)
  • City, State and ZIP code (on the same line)*
  • Country*

*(for letters or packages going outside the USA, contact the Mail Center staff for any questions on address formatting for mailing internationally)
