Wait at least 7 days after the mailing date, then file a Missing Mail search at MissingMail.USPS.com, and file an insurance claim if you bought coverage. That is what to do if USPS lost my package, and the order matters because the two requests run on different clocks.
Most “lost” packages are late, misrouted or sitting at a facility with no scan. The steps below separate those cases from a package that is truly gone, and show what the sender and the recipient can each do.
How to know if USPS lost your package
USPS does not send a notice that a package is lost. You have to read the tracking history and decide when the silence has gone on too long.
- Check the tracking page first. A package with no new scan for several days is often just between facilities.
- Look for odd statuses, such as a scan in the wrong state. That can mean the package was misrouted, which is covered in what a USPS missent package means.
- If tracking says delivered and nothing arrived, use the steps in the guide to a package marked delivered that never showed up.
USPS does not publish a day count after which a package officially counts as lost. The first hard number is the 7 day mark for a Missing Mail search, so treat that as your starting line.
What to do if USPS lost my package, step by step
- Check tracking and your address. Confirm the label was correct and look around the porch, mailroom, neighbors and parcel locker.
- Wait until 7 days have passed since the mailing date. USPS will not accept a Missing Mail search earlier than that.
- File the search at MissingMail.USPS.com. You need one request for each mailpiece.
- Gather the paperwork for a claim if the item was insured. Keep the receipt, proof of value and tracking number.
- File the claim inside its window, which is listed in the timeline table below.
Both the sender and the recipient can run the first three steps. A package that has not moved is easier to chase when the sender has the receipt, so ask them for it early.
How to report a missing package to USPS
The USPS Missing Mail page sends you to an online form. You can submit it starting 7 days after mailing and up to 365 days after mailing.
Have these details ready before you start:
- The sender and recipient addresses.
- The mailing date.
- The tracking number, which USPS recommends but does not strictly require.
- A description of the container, such as the box or envelope.
- A description of the contents, with photos.
A draft that you save expires after 7 days, so finish it in one sitting. You can cancel a request at any time.
After you submit, USPS emails a confirmation and periodic updates. If the item is found, USPS forwards it to the address you gave. USPS says plainly that sometimes it cannot find the item.
What the request statuses mean
| Status | What it tells you |
|---|---|
| Saved as Draft | You started the form but did not submit it, and the draft expires after 7 days |
| Accepted | USPS received the request and is searching |
| Mailpiece Found | The item was located and will be forwarded to the address on the request |
| Rejected | USPS did not accept the request, so check the details and the item type |
| Expired | The request or draft ran out of time |
| Canceled | The request was canceled, which you can do at any time |
Items USPS will not search for
Missing Mail searches are not available for hazardous materials, live ammunition, opened beauty products, over the counter or prescription drugs, perishables or handguns. USPS also says Customer Care representatives cannot submit a search for you, so for those items the remaining path is an insurance claim, if the contents were insured and allowed in the mail.
Missing Mail search vs insurance claim vs refund
These are three separate remedies. A search tries to find the package, a claim pays you for it, and a refund returns postage.
| Remedy | What it does | Who can file | When |
|---|---|---|---|
| Missing Mail search | Asks USPS to locate the item and forward it | Sender or recipient | From 7 days to 365 days after mailing |
| Insurance claim | Pays for lost, damaged or missing contents on insured mail | Sender or recipient | See the timeline table below, and always before 60 days |
| Postage refund | Returns postage on Priority Mail Express that missed its guaranteed arrival time | Whoever holds the Label 11 receipt, normally the sender | 2 to 30 days after mailing, or 30 to 60 days if an extra service was bought |
The 365 day search window and the 60 day claim window do not conflict. They belong to different processes, so do not wait a year to start a claim.
Timeline: when to file by service
Claim timing depends on the service you used. The earliest date to file a lost package claim and the cutoff both count from the mailing date.
| Service | Missing Mail search opens | Claim opens for a lost package | Claim closes |
|---|---|---|---|
| Priority Mail Express | After 7 days | After 7 days | Before 60 days |
| Priority Mail | After 7 days | After 15 days | Before 60 days |
| USPS Ground Advantage | After 7 days | After 15 days | Before 60 days |
| Insured Mail or COD | After 7 days | After 15 days | Before 60 days |
| Registered Mail | After 14 days | After 15 days | Before 60 days |
| Parcel Select | After 14 days | Not published on the USPS claims page | Not published |
Not sure which service you paid for? Check the receipt or label. Slower services are covered in the guide to USPS Ground Advantage.
Normal delay vs when to worry
A late package is not a lost package. Use the delivery time estimator to see what a normal transit time looks like before you decide anything is wrong.
| Situation | What to do |
|---|---|
| Fewer than 7 days since mailing, tracking still showing movement | Wait and keep checking tracking |
| Fewer than 7 days, tracking stalled | Check the address and call tracking support, but a Missing Mail search is not open yet |
| 7 days or more since mailing, no delivery | File a Missing Mail search |
| Registered Mail or Parcel Select, 14 days or more | File a Missing Mail search |
| Insured package, 15 days or more (7 days for Priority Mail Express) | File a claim, keeping the 60 day cutoff in mind |
| Contents or label suggest theft | Contact the Postal Inspectors |
The one real deadline to protect is the 60 day claim cutoff. If you were hoping the package would turn up, still mark the date on your calendar so the claim window does not close while you wait.
Who to call or contact at USPS
If the online form does not fit your case, USPS has phone and online support. The USPS contact page lists the options.
| Need | Contact |
|---|---|
| General help | 1-800-ASK-USPS (1-800-275-8777) |
| Tracking questions | 1-800-222-1811 |
| Claims, PO Boxes and accounts | 1-800-344-7779 |
| Written request | The email form at emailus.usps.com/s/, or chat on USPS.com |
| Deaf or hard of hearing | TTY or TRS by dialing 7-1-1 |
Each of those phone lines runs Monday to Friday 8 AM to 8:30 PM ET and Saturday 8 AM to 6 PM ET. Call when you have the tracking number and mailing date in front of you. One limit to know: USPS states that Customer Care representatives cannot submit a Missing Mail search for you, so the online form is the only way to open one.
How to give the search the best chance
The Missing Mail form is only as good as what you put in it. A vague request is harder to match to a package that USPS may already be holding.
- Describe the container exactly, including its type, color and any visible marks.
- List the contents in plain terms and attach clear photos of the items.
- Enter both addresses the way they appear on the label, including any apartment number.
- Use the real mailing date, because the 7 day and 365 day limits count from it.
File one request per package. If you sent several boxes, each needs its own search, and each can have its own tracking number.
Does USPS reimburse for lost packages?
Only in some cases. USPS may not legally pay for an uninsured lost or damaged item. Refunds apply to services that carry a guarantee, such as Priority Mail Express, and claims pay out on insured mail.
To file a claim, you need the original mailing receipt or proof of the electronic label, proof of value and the tracking number. Online filing is the fastest route. You can also request paper forms by phone at 1-800-332-0317.
The USPS claims page says either the sender or the recipient may file for insured mail that is lost, damaged or missing contents. See the USPS claims page for the current form.
Priority Mail Express postage refunds
A Priority Mail Express refund is separate from a claim and covers the postage, not the contents. USPS accepts the request from 2 to 30 days after the mailing date, or from 30 to 60 days if an extra service was bought with the label. You can apply online with a free USPS.com account, or at any Post Office by filling out Part I of Form 3533 in duplicate and handing it in with your original customer copy of Label 11.
The 30 day refund window closes well before the 60 day claim cutoff, so start the refund request as soon as the guaranteed time has passed.
What the sender and recipient can each do
| Person | Best first move | Why |
|---|---|---|
| Sender | File the Missing Mail search and keep the receipt | The sender holds the proof of mailing and value that a claim needs |
| Recipient | Check tracking, then ask the sender for the tracking number and receipt | The recipient can also file, but needs those details |
| Either | Call 1-800-222-1811 for tracking support | Tracking support is open Monday to Friday 8 AM to 8:30 PM ET and Saturday 8 AM to 6 PM ET |
If the package was bought online, the store may replace or refund it on its own terms. That is separate from USPS and often quicker, so ask the seller too.
If you are still unsure what to do if USPS lost my package in your case, start with the checks below and then match your dates to the table above. The order never changes: look, wait for the window, search, then claim. Each step also builds the record you need if the package never turns up.
How to find a lost package before you file
A few checks take minutes and solve a surprising share of cases. Do them while you wait for the 7 day mark.
- Read the full tracking history, not only the latest line, and note the last facility that scanned it.
- Compare the delivery address on the label with the one you meant to use. A typo in a unit number is a common cause.
- Check with neighbors, your building office and any parcel locker. The guide to USPS parcel lockers explains how a package can end up in one.
- Ask whether the package was held for pickup. The rules are in how to pick up a package from USPS.
If one of those turns it up, you can cancel the Missing Mail request. If none does, you already have the facts the form asks for.
What happens if USPS loses your package
There are three possible outcomes. USPS finds the package and forwards it, USPS cannot find it, or the package is declared lost and you move to a claim or refund.
If USPS finds it, the item is sent on to the address in your request. If it cannot, the Missing Mail request does not pay you anything on its own. Your money comes back only through an insurance claim or a refund on a guaranteed service.
That is why the purchase decision matters more than the search. Insurance and a guaranteed service are the two things that turn a lost package into a payout. Without either, USPS may not be able to pay, and the store you bought from may be your better path.
If you think the package was stolen
If you suspect theft or fraud, USPS points you to the Postal Inspectors at uspis.gov. A Missing Mail search will not investigate a crime, so report the theft there and keep the tracking record.
For a wrong address on a package that is still moving, changing the USPS delivery address may save it before it counts as lost.
Bottom line: what to do if USPS lost my package
Give it 7 days, then file the Missing Mail search, and file an insurance claim only if the package was insured and the window is open. Without insurance or a guarantee, USPS may not pay, so the best outcome is usually finding the package. Next time, see how to ship a package with USPS and add coverage when the contents matter.
