12-5 Time Limit for Complaints and Issues

Handstamps must be retained for 6 months. All complaints and issues for nonreceipt of covers submitted for servicing by the Postal Service must be sent to the appropriate Post Office no later than 60 days from the date of postmark or from the date postmarks were last applied. Complaints and issues for replacement postmarks filed after 60 days are not honored, but the postmaster must respond to the customer with a short explanation that the request could not be honored because it was filed after the deadline.
