USPS Certified Mail FAQ

Certified Mail is a USPS service that gives mailers an official receipt providing poof the item was mailed. After the Certified Mail document is delivered, the mail carrier requires a signature from the recipient. Mailers using Certified Mail can also request a physical or electronic Return Receipt with the recipient’s signature. Here are some of the most frequently asked questions about the USPS service:

How long will it take for USPS to deliver my Certified Mail letter?

Delivery time depends on the mail class chosen to add the Certified Mail service to. If you are sending a First-Class Mail letter, delivery usually takes 2 to 5 business days. For Priority Mail, delivery is usually within 2-3 business days. However, USPS does not guarantee an exact delivery time for either First-Class Mail or Priority Mail.

Why would I use Certified Mail?

Mailers typically use certified mail when they need to provide proof that a mailpiece was sent and received. The most common uses of Certified Mail are to send tax returns, bank documents, and time-sensitive communications with debtors or creditors.

Do I have to be present at a Post Office to send Certified Mail?

No, as long as you affix the proper Certified Mail Forms and the correct amount of postage, you can have a USPS mail carrier pick up your Certified Mail mailpiece or drop it in a mailbox.

Can Certified Mail go to a P.O. Box?

Yes, when Certified Mail arrives at the delivery Post Office, the letter carrier will place a delivery notification inside the P.O. Box that instructs the person to present the delivery slip to the window clerk. Keep in mind that a recipient is under no legal obligation to sign the delivery slip regardless of where the mailpiece is delivered.

Can anyone at the mailing address sign for Certified Mail?

Yes, with standard Certified Mail anyone present at the mailing address can sign for the mailpiece. If you send a mailing with restricted Certified Mail, however, only the person who it is addressed to may sign for it.

Which name goes on the receipt, mine or the person I am mailing it to?

On the green and white “Certified Mail Receipt”, write the name of the person you are mailing the mailpiece to. Their address should be entered at the bottom.

If the Certified Mail is returned to sender as not deliverable, should the sender sign the green card?

No, the sender should not sign it. The fact that it was returned as undeliverable with the unsigned green card intact is proof that you tried to send it.
