How to Find a Lost USPS Letter or Package

The U.S. Postal Service processes over 6,400 items each second, totaling an estimated 160 billion mail pieces yearly. USPS delivers the vast majority of these items without any incident. 

However, sometimes a package gets lost or doesn’t arrive at its destination on the delivery date. When this happens, you can start the search process by contacting USPS. 

How to Start Your Search

USPS provides ways to resolve lost mail or packages to help you address your issues quickly. 

Check the Current Status

Check the current status of your package through the tracking services provided by USPS. You only need to log in to your account and track your package from there. 

Another easy way to track your package is through a mobile app. You can download the Circuit Package Tracker app available for iOs or Android.

Track Your Package and Double Check Your Tracking Info

You can monitor your package through its assigned tracking number. You get this number from USPS through confirmation emails and receipts. 

Simply enter the tracking number into the USPS Tracking page, and check your package’s delivery status online. 

A tracking number is a long string of numerals assigned to your package. Some tracking numbers go up to 35 characters long, making prone to mistyping. 

After typing your tracking number into the tracking system, double-check if the information you’ve provided is correct. Review your tracking information carefully before you file a complaint about a lost package. 

Complete a Help Request Form: How to Complete the USPS Help Request Form

After checking your package status and finding no updates, you can complete a help request form that USPS provides. You can provide the information needed and hit submit. 

USPS will then try to locate your package. If found, you’ll get a notification. Otherwise, you can start a missing mail search request. 

Submit a Missing Mail Search Request: How to Submit a USPS Missing Mail Search Request

Sometimes, USPS cannot locate your package after you’ve filed an initial help request. In this case, you can file a missing mail search request after seven business days. 

You need to provide the following information to start a missing mail search. 

  • Sender’s mailing address
  • Recipient’s mailing address
  • Size and type of envelope or container used
  • USPS Tracking number(s) 
  • The mailing date from your mailing or Click-N-Ship label receipt
  • Your package’s description, brand, model, color, or size, if applicable
  • Pictures of the item for easier recognition

What to Expect Next

Missing mail or packages is frustrating for both the sender and recipient. When you’re in this kind of situation, here are things that you should expect. 

Wait Another Day or Two

You’re advised to wait for a day or two before filing an initial help request. Sometimes, delays happen primarily due to the massive volume of packages the company processes daily. 

It’s best to wait for at least two days to allow delayed deliveries to push through. If your package hasn’t arrived after two days, you can now file a mail search request. 

USPS Mail Search

When USPS receives your missing mail request, you’ll receive a confirmation email and periodic updates on the status of your search request. 

Once USPS finds your package, they’ll send your package straight to the address you’ve provided. 

Requesting a Refund: How to File a Refund or Insurance Claim

The worst case is that your package has been lost and is irrecoverable. If this happens, you can request a refund or an insurance claim if you purchased insurance. 

You need the following to start a refund request:

  • Your package’s tracking number
  • Proof of purchase
  • Photo ID (if in person)

You can apply for this request online and at your local post office. 

File a Claim

You could file an insurance claim if you insured your letter or package that got lost, damaged, or arrived with some of its contents missing. As the claimant, you must have the original mailing receipt, proof of insurance, proof of value, and proof of damage.
