USPS Package Lost? Missing Mail Search, Claims, and Refunds

If your USPS package hasn’t arrived, start a free Missing Mail Search Request at MissingMail.USPS.com once seven days have passed since the mailing date, and if the package had insurance, file a USPS lost package claim at usps.com/help/claims.htm for reimbursement of the item’s value. Either the sender or the recipient can file the claim, and most USPS shipping services include at least $100 of insurance automatically.¹

Check Before You File Anything

A few quick checks resolve more “lost” packages than people expect. Pull up your tracking number at USPS.com and read the last scan. A package sitting on “In Transit” for several days is usually delayed, not lost. A “Delivery Attempt” scan means the carrier couldn’t complete delivery, so the package is likely at your local post office waiting for pickup or a second try.

The trickier case is a “Delivered” scan with no package in sight. Carriers sometimes tuck items behind bushes, inside screen doors, or hand them to a neighbor or building manager. Walk the property, ask anyone in your household, and check with a front desk if you have one. If you use USPS Informed Delivery, log in to confirm the address on incoming mail matched yours.²

Confirm the shipping address with the sender too. One wrong ZIP digit can send a package across the country. USPS asks you to wait at least seven days from the mailing date before filing a formal search, and some services require longer: Priority Mail Express is seven days, Registered Mail is fourteen, and Parcel Select is fourteen.³

Submit a Missing Mail Search Request

Once the waiting period is up, go to MissingMail.USPS.com and sign in with a USPS.com account. The search is free and separate from any insurance claim. Its point is to put USPS employees on the ground actively looking for your package inside sorting facilities, trucks, and post offices along the delivery route.³

Have this ready when you file:

Sender and recipient addresses
Date of mailing
Tracking number (strongly recommended)
Description of the package: type, size, and color
Description of the contents: title, color, size, brand, make, model, and photos if you have them

Detail matters. “Brown box, 12 by 10, covered in stickers, containing a red KitchenAid mixer” is far more findable than “box with kitchen stuff.” USPS emails a confirmation number and sends status updates as the search progresses. You have up to 365 days from the mailing date to submit a search request, but filing sooner gives the package a better chance of being found before it moves on to the USPS Mail Recovery Center.³

File an Insurance Claim

A claim is your request for USPS to reimburse the value of a lost or damaged item. It only applies to packages with insurance coverage, and several USPS services include insurance automatically:

Priority Mail Express: up to $100 included
Priority Mail: up to $100 included
USPS Ground Advantage: up to $100 included
Registered Mail: can be insured up to $50,000
Media Mail: no automatic insurance

For items worth more than $100, additional insurance can be purchased at the time of mailing, starting at $2.70 and covering shipments up to $5,000 in declared value.⁴

Who Can File

Either the sender or the recipient can file. Whoever files needs the original mailing receipt, so the sender is usually in the better position. If you’re the buyer, coordinate with the seller first. Two separate claims for the same package just create confusion and delay.¹

Filing Deadlines

Each service has a window. File too early and the system rejects the claim because USPS still considers the package in transit. File too late and you lose your right to compensation. All deadlines run from the mailing date, not the expected delivery date:

Priority Mail Express: 7 to 60 days
Priority Mail: 15 to 60 days
USPS Ground Advantage: 15 to 60 days
Registered Mail: 15 to 60 days
Insured Mail (general): 15 to 60 days
Damaged or missing contents (any service): file immediately, no later than 60 days

Military APO/FPO/DPO addresses get longer windows, ranging from 21 days to one year depending on the service.¹

What You Need to Submit

File online at usps.com/help/claims.htm or by mail with a paper form. Before you start the online form, gather three pieces of documentation:

Proof of insurance: the original mailing receipt or electronic shipping label record
Proof of mailing: tracking number or shipping confirmation
Proof of value: sales receipt, invoice, credit card statement showing the purchase amount, or a canceled check

Items insured above $500 have an extra requirement: the sender must have used PS Form 3813-P (the over-$500 insured mail receipt) at the time of mailing. Without it, proving the declared value gets much harder.⁵

What USPS Pays

If the claim is approved, USPS pays the lesser of the item’s actual value or the declared insurance amount. Original postage is refunded when the item was lost or never delivered. The insurance fee itself is not reimbursed. Payment comes by check or direct deposit.⁶

USPS aims to process claims within 30 days. Straightforward ones can wrap up in five to ten business days; others take several weeks, especially if USPS asks for more documentation. Claim status is available anytime through the USPS claims portal.¹

Appealing a Denied Claim

A denial isn’t the end. USPS offers two levels of appeal, each with a 30-day deadline from the date you received the previous decision.

First appeal: submit within 30 days of the original denial using the same method you used to file (online or by mail). Address the specific reasons USPS gave and include any new documentation that answers them.
Final appeal: if the first appeal is denied, you have another 30 days to file a second and final appeal through the same channel.

The most common reason claims get denied is insufficient proof of value. If that was the problem, sending the missing receipt with your first appeal often resolves it. Resubmitting the same paperwork rarely changes the outcome.¹

If the Package Wasn’t Insured

USPS won’t reimburse a lost package that had no insurance coverage. If you bought the item from a retailer or online seller, though, you have other options.

Start with the seller. Many retailers reship or refund orders that never arrive regardless of fault. Marketplaces like Amazon, eBay, and Etsy have buyer protection policies that cover lost shipments, and they generally lean toward the buyer when tracking can’t confirm delivery.

If the seller won’t help, check your payment method. PayPal’s Purchase Protection covers items that were never received. Open a dispute in PayPal’s Resolution Center, escalate it to a claim, and provide whatever documentation PayPal requests. If the seller can show proof of delivery, PayPal typically sides with them.⁷

Many credit cards also offer purchase protection covering items lost within 60 to 120 days of purchase, though coverage limits and exclusions vary and some cards only protect against theft and damage rather than shipping loss. Check your card’s benefits guide or call the number on the back of the card. A chargeback is another option if the merchant refuses to resolve the issue.

International Packages

Lost international packages follow a different track. Before you can file a claim, you have to submit an international inquiry, which is the equivalent of a missing mail search but involves coordinating with the destination country’s postal service. The filing windows depend on the service:

Priority Mail Express International: inquiry between 3 and 90 days from mailing
Priority Mail International (most countries): inquiry between 7 days and 6 months from mailing
Priority Mail International (Canada): inquiry between 10 days and 6 months from mailing
Registered Mail International: inquiry between 7 days and 6 months from mailing

First-Class Mail International and First-Class Package International Service are not eligible for inquiries or claims at all, so USPS provides no recourse if those items go missing.⁸

Priority Mail Express Late-Delivery Refunds

Priority Mail Express carries a money-back guarantee for late delivery, and it’s separate from an insurance claim. If a Priority Mail Express package misses its guaranteed delivery window, you can request a postage refund at usps.com/help/refunds.htm using your tracking number and purchase receipt. The refund applies even if the package eventually arrives, because it compensates for the late delivery itself rather than for lost contents.⁹
