USPS: How Can I Find My Correct Mailing Address?


Guam – U.S. Postal Service Corporate Communications Specialist Duke Gonzales told the K-57 Breakfast show this morning that one reason for the increase in returned mail is that the Postal Service on Guam has recently switched from manual mail sorting to a computerized system.

The computer kicks back addresses that are not in its data base, and those addresses he said are provided by the local government, not the postal service.

For those residents or businesses who have experienced problems with returned mail, Gonzalez suggests the following steps to correct the problem.

·         Customers can obtain their correct addresses by using’s Look Up a ZIP Code tool. Here are the simple steps involved:

  1. Navigate to
  2. Click on the Quick Tools drop box on the left
  3. Click on Look Up a ZIP Code
  4. That will open up another page on which you can enter your street address in the spaces provided, then click Find.
  5. Your correct mailing address will pop right up on the next page.

·         Postal customers should then notify anyone who sends them mail to use their correct and complete mailing address.
