USPS OIG: Where’s My Mail?

USPS OIG Blog – May 26, 2020
With three agencies that have “U.S. Postal Service” in their names, and each one having different responsibilities and jurisdictions, it’s no wonder people sometimes aren’t sure where to turn for help with lost, delayed, or damaged mail.

With the Postal Service solely responsible for mail delivery, it’s almost always the one to contact. But some circumstances warrant notifying us here at the OIG, or the U.S. Postal Inspection Service. Our blog infographic illustrates the options, with links and contact information below.

Postal Service

  • For delayed mail, either domestic or international, call 1-800-275-8777 to file a complaint. Or go to USPS online, choose the tab marked “Where is My Package” or “Where is My Mail.”
  • For lost or damaged mail, file a claim for either international mail or domestic mail.


  • File a complaint with our Hotline if you suspect wrongdoing by a postal employee or contractor.

Postal Inspection Service

  • If you suspect someone who does not work for USPS has stolen your mail call 877-876-2455 or report it online
