What Is USPS Signature Confirmation?

When sending a package, USPS Signature Confirmation is an added service requiring your recipient or responsible party to sign for the package’s release to them.

This service ensures the recipient is physically present to receive your package. Signature Confirmation also requires them to show a valid photo identification (I.D.) to confirm their identity.

With Signature Confirmation, USPS will hand the package over once the courier obtains a signature from the recipient.

After delivering the package, USPS relays the delivery confirmation to the shipper. The information includes the date, time, and delivery location.

For unsigned packages, the courier returns them to the local delivery hub. The USPS delivery driver leaves a paper notice at the recipient’s address and sends an online notification informing you that they attempted delivery.

These notifications allow you to verify the package’s status and whether the courier has delivered the item safely.


A few notes to remember when adding the Signature Confirmation service to your packages:

  • Depending on your chosen mail class, you can purchase the service at a USPS post office or online.
  • You can use this add-on with any mail service except USPS Marketing Mail and Adult Signature services.
  • The recipient must show an acceptable primary I.D. containing a clear photo before the courier hands the package to them.

When you or the recipient adds the Signature Confirmation add-on to your delivery, USPS will only require the recipient’s signature before handing the package to the receiver. This add-on often applies to expensive products likely to be damaged or stolen.

Why Does USPS Require a Signature?

USPS requires a signature upon delivery when you request it as part of the Signature Confirmation service.

If you’re the shipper, you may have several reasons to require a signature. One excellent reason is when you need to send a highly valuable item and want to ensure it safely gets to the correct recipient.

Without a signature indicating the recipient’s acceptance, your package risks being left outside. This situation can expose your item to theft or damage, such as when it’s raining or snowing.
