How to complain about USPS

Work through the stages in order. Each one creates the paper trail the next stage needs.

  1. 1

    Stage 1

    Call or contact USPS

    As soon as the problem happens

    Call 1-800-ASK-USPS (1-800-275-8777), TTY 711, or use the online help pages. Have your tracking number, addresses and dates ready.

    If the call does not fix it

    Take the problem to the station manager or postmaster at your local post office. USA.gov lists this as an escalation step.

    Take your tracking number and any evidence.

    Local managers can often act on delivery problems quickly.
