How Does US Postal Service Tracking for Certified Mail Work?

Certified Mail is used for important notifications that often deal with medical debt collection, warrants, property liens, credit information, and other legal matters. Because of this, senders are often required to have proof that the letter was mailed via Certified Mail. A Certified Mail letter provides the sender proof in two ways. First, it provides proof the letter or package was mailed. Second, it provides proof the letter or package was delivered. The US Postal Service tracking is the third party that provides proof of compliance.

What About Tracking and Proof of Delivery?

The Postal Service will attempt to deliver the Certified Mail items two times. The attempted date and time of delivery are recorded. If the item cannot be delivered, it will be returned to the sender with proof from USPS that the item was undelivered or refused. This process provides the sender with proof of the attempted delivery using the tracking numbers. The record is kept for 10 years as proof of compliance for the sender.
