Yes, you can trace a lost USPS package, and the fastest way to start is by filing a Missing Mail Search request on the official USPS website or at your local post office. This triggers a formal trace that asks USPS employees along the route to look for your item, and it is the only official method that moves your case beyond a simple tracking lookup.
What a USPS Trace Actually Does
A USPS trace, officially called a Missing Mail Search, is a request that USPS opens a file on your package and circulates its details to the processing facilities, post offices, and carriers that may have handled it. The system checks for scans, looks at security footage in some cases, and asks employees to physically search the area where the package was last scanned. It is not an instant answer; USPS says most search results come back within 3 business days, but some cases take up to 30 days or longer, especially if the item moved between multiple facilities.
You can file a trace for any package that has gone without a tracking update for 7 days or more, or if the tracking shows “Delivered” but you did not receive it. For international shipments, the same Missing Mail Search form works, but the search may take longer because USPS must coordinate with foreign postal services.
Before You File: Check These First
Many people file a trace when the package is simply sitting in a facility or was left in an unexpected place. Before you start the official process, do these quick checks:
- Look at the tracking details for a “Delivered” scan and check around your property, including porches, mailrooms, and with neighbors or building managers.
- Wait 24 hours after a missed delivery attempt; carriers sometimes mark items as “available for pickup” without leaving a notice.
- Search the tracking number on the sender’s order page; sometimes the sender has a different internal reference that updates faster.
- Verify the address you gave the sender. A single typo in a street number or ZIP code can send a package to the wrong carrier route.
- Check if the package was insured or had a service like Priority Mail Express with a money-back guarantee; those have different claim processes.
If none of these reveal the package, then filing a Missing Mail Search is the correct next step.
How to File a USPS Trace: Step by Step
You have two ways to file: online or in person. Both require the same basic information, so gather your tracking number, the sender and recipient addresses, and a description of the contents.
- Go to the USPS Missing Mail Search page at usps.com/help/missing-mail.htm.
- Click “Start Your Missing Mail Search” and sign in with a free USPS.com account. If you do not have one, create it with an email address.
- Enter the tracking number and the date you shipped or expected delivery.
- Fill in the package details: weight, dimensions, and a description of the contents. Be specific — “small box, 2 lbs, contains a blue scarf” is better than “clothing.”
- Provide the mailing address and your contact information.
- Submit the form and save the confirmation number. You will receive email updates when USPS adds notes to the case.
You can also visit your local post office and ask a clerk to file a Missing Mail Search in person. Bring the tracking number and a photo ID. The clerk will fill out the same form and give you a receipt. In-person filing does not speed up the search, but it can be helpful if you have questions about your specific situation.
What Happens After You File the Trace
Once your search is filed, USPS assigns it a case number. The service sends your package details to the facilities where scans were last recorded, and those facilities are asked to check their sorting machines, bins, and undeliverable mail areas. You may see a new tracking scan appear within a few days, which often means the package was found and is moving again. If the package is not found, USPS will eventually mark the case as “Search Completed” and you will receive a final email.
If your package was insured, you can file a claim after the search concludes. For Priority Mail Express, you can file a claim for the postage and the declared value if the item is lost. For regular Priority Mail, insurance up to $100 is included, but you must file a claim within 60 days of the mailing date. Standard First-Class packages do not include insurance, so a trace may be the only recourse, and if the item is not found, you may have no reimbursement.
Common Reasons Packages Get Stuck
Understanding why a package disappears helps you know what to expect from a trace. Most lost mail falls into a few categories:
- Incorrect or incomplete address: Missing apartment numbers or wrong ZIP codes cause packages to bounce between facilities.
- Damaged label or packaging: If the label tears off, the package goes to the Mail Recovery Center in Atlanta, where it is held for 30 days before being opened.
- Missed scan: Packages can travel without being scanned at every point, so a gap in tracking does not always mean the item is lost.
- Left at the wrong address: Carriers occasionally deliver to a neighboring address. A trace can help identify the delivery route, but you may need to ask neighbors directly.
- Stolen after delivery: If tracking shows “Delivered” but you never saw the package, a trace will not help. You need to file a police report and contact the sender.
The Mail Recovery Center in Atlanta is the final destination for undeliverable items. After 30 days, they open and catalog the contents, and you can search their online database if you have a claim number. However, most packages are returned to sender before reaching that point.
USPS Trace vs. Insurance Claim
A trace and an insurance claim are two different processes. The trace is a search; the claim is a request for money. You can file both, but the claim usually requires the search to be completed first. If you have insurance, the claim form asks for the value of the contents and proof of that value, such as a receipt or a screenshot of the online order. USPS will not pay a claim just because the package is late; it must be declared lost, which typically means 30 days have passed for domestic mail or 60 days for international.
If you did not purchase insurance, your only option is the trace, and if the item is not found, you have no financial recourse from USPS. The sender may offer a refund or replacement, but that is a private arrangement, not a USPS policy.

Frequently Asked Questions
How long does a USPS trace take?
USPS says most Missing Mail Searches produce a result within 3 business days, but some cases take up to 30 days. If the package is not found after 30 days, the case is closed and you may be eligible for an insurance claim if you purchased coverage.
Can I trace a package without a tracking number?
No, USPS requires a tracking number to file a Missing Mail Search. If you lost the number, ask the sender for it, or check your email receipt if you shipped it yourself. Without a tracking number, there is no way to identify the package in the system.
Does USPS pay for lost packages without insurance?
No, USPS only pays for lost packages if you purchased insurance or used a service with included coverage, such as Priority Mail (up to $100) or Priority Mail Express (up to $100). First-Class packages have no included insurance, so a trace is your only option.
What if the package was marked delivered but I didn’t get it?
First, check with neighbors, your mailroom, or the area around your door. If it is truly missing, file a Missing Mail Search anyway — USPS can look at the delivery scan and the carrier’s route. If you suspect theft, file a police report and contact the sender, as USPS will not cover theft after delivery without insurance.
Can I file a trace for an international package?
Yes, you can file a Missing Mail Search for international packages, but the process takes longer because USPS must contact the destination country’s postal service. You need the tracking number and the exact address used. International claims have different deadlines, so check the USPS website for details.
