Why Did Tracking Stop on My Certified Mail Letter?
The USPS Help Line is 800-275-8777. If tracking has stopped, we suggest you visit USPS web site www.usps.com. to get the latest tracking information. Updated delivery information does not occur until the USPS letter carrier updates the status of the letter or package.
If it has been more than 3 weeks and you see no updated delivery information we suggest calling the LOCAL USPS Post Office responsible for the letter's final delivery. In other words, the Post Office closest to the final delivery address Zip Code should know why it has not been delivered.
To locate the closest USPS Post Office responsible for mail delivery call 800-275-8777 and be ready to provide them the Zip Code of the final letter's delivery address.
