Step-by-step
- 1Contact customer service — in writing
Open a ticket and get a case number, then confirm every phone call by email. With USPS, the written record is what later moves the case forward.
- 2File regulatory complaints
Complaints to Postal Regulatory Commission (USPS), FTC, State Attorney General typically route to a team with authority to resolve, unlike frontline support.
- 3Send a demand letter by certified mail
State the facts, the statute, the exact amount you want, and a 10–14 day deadline. Send it to USPS's registered agent as well as customer service.
- 4File in small claims court
If the deadline passes, file where you live. Bring your timeline, receipts, the demand letter, and the certified mail receipt.
USPS-specific tips
Carrier claim denials are usually based on packaging or declared-value clauses. Ask for the specific tariff provision relied on — many denials cannot cite one.
Check USPS's current BBB rating and complaint volume before you write — a pattern of similar complaints strengthens your own claim and is worth citing.
