How Signatures Work
Once your letter is delivered, USPS captures the recipient’s signature. It will appear in your Job History. You can click “Signature” to download the file when available.
When a Signature May Not Be Available
A signature may not be provided if:
- The mailpiece is still in transit
- The letter is undeliverable or returned
- It was sent to an APO/FPO (military) address
- USPS does not capture a signature
- USPS is unable to deliver the letter
What to Do If It’s Missing
If you expected a signature:
- Wait up to 3 business days after delivery
- Check tracking directly at USPS.com
- If still unavailable, contact USPS or resend the letter
