Delayed, Lost, or Stuck Certified Mail

Getting Started

Certified Mail is a good option when you need proof that a letter was mailed and accepted by USPS, along with tracking and, when Electronic Return Receipt (ERR) is included and successfully delivered, proof of delivery.

However, Certified Mail does not guarantee delivery by a specific date or successful delivery. USPS tracking can sometimes contain delayed, missing, repeated, or incomplete scans, and a mailpiece may continue moving through the USPS network without receiving an expected tracking update.

Once LetterStream has completed your mailing and USPS has accepted it, transportation, tracking updates, delivery attempts, and final delivery are handled by USPS.

Common Reasons for Delays

Certified Mail may be delayed or appear stuck due to:

  • Incorrect or incomplete recipient address
  • Missing suite, department, mailroom, or attention information
  • Different mailing requirements used by a recipient business or organization
  • USPS processing or routing delays
  • Missing or delayed USPS tracking scans
  • An unsuccessful delivery attempt or recipient pickup requirement
  • Weather or other USPS service disruptions

How to Track Your Letter

You can review tracking details directly through your LetterStream account or enter the Certified Mail tracking number on USPS.com.

Keep in mind that USPS tracking is not continuous location monitoring. A letter may move through the USPS network without receiving an expected scan. For more information about typical mailing timelines and what to expect after LetterStream completes a job, see Estimated Delivery Timeframes.

If your mailing included Electronic Return Receipt, you may also see a Return Receipt Electronic section on the USPS tracking page that can be used to request information directly from USPS.

Steps to Take

If your Certified Mail has been delayed for an extended period:

  1. Continue monitoring the tracking number. A delayed mailpiece may still continue moving and ultimately be delivered.
  2. Confirm the recipient address. Double-check the full address, including any apartment, suite, department, mailroom, or attention information. Businesses and organizations may use a different mailing address than their physical location.
  3. Verify the address with USPS. The USPS Address Verification tools may help confirm that the address is recognized and properly formatted.
  4. Contact USPS directly. Provide the tracking number and ask USPS to investigate the delayed mailpiece. LetterStream only has access to the tracking information USPS provides and does not have access to their internal transportation or delivery systems.
  5. Consider sending another copy if needed. If the mailing is time-sensitive, you may wish to resend it while continuing to monitor the original.

Proof of Mailing and Proof of Delivery

Even when delivery is delayed or unsuccessful, Certified Mail can still provide useful evidence that the letter was mailed and accepted by USPS.

If your primary need is to document that the original mailing was sent, see Certified Mail - Supporting Evidence of Mailing for additional records that may be available.

If Electronic Return Receipt was selected, the ERR serves as proof of delivery when USPS successfully delivers the mailpiece, captures the signature, and provides the record.
