USPS Certified Mail: How It Works, Cost & Tracking

Understand USPS Certified Mail, costs, tracking, Return Receipt, Registered Mail comparisons, and delivery edge cases.

What Certified Mail gives you

Certified Mail is a USPS extra service that provides a mailing receipt and, upon request, electronic verification of delivery or attempted delivery. USPS maintains a delivery record that includes the recipient's signature. The sender can obtain a copy of the delivery record by purchasing Return Receipt at the time of mailing.

Certified Mail Refused or Returned Unclaimed: What It Means and What to Do Next

Refused and unclaimed Certified Mail are different USPS outcomes, and real rules treat them differently. Read the endorsement, see how much of your deadline the 15-day hold uses, sort your notice rule by its wording, and choose a permitted follow-up.
