When should I file a USPS Missing Mail search instead of a claim?

File a Missing Mail search from 7 days after the mailing date when tracking has stalled or the package hasn't arrived; it works for mail with no insurance, which can't be claimed. If the package was insured, including the $100 with Priority Mail and Ground Advantage, the claim window for a lost package opens at day 15, and you can do both.

Fees from USPS Notice 123 effective Oct 4, 2026 (the same since Jul 12, 2026); rules quoted from the Domestic Mail Manual and usps.com, each with its section. USPS decides every claim and refund; this is a guide to its published rules.

What to include

The sender's and the recipient's mailing addresses.
The size and type of box or envelope.
The tracking number, the mailing date from your receipt, or the Click-N-Ship label receipt.
A description of the contents: what it is, brand, model, color or size.
Pictures that could help USPS recognize the item; photos of the actual item or the listing photos.

That list is from USPS's Missing Mail page. A label printed from a selling platform still has a USPS tracking number to give.

What happens next

USPS sends a confirmation email and periodic updates, and if it finds the package it sends it to the address you provided.

“sometimes we cannot find missing mail items. It is also possible that your package or mail will not be recovered because it was not safe to forward.”

Uninsured packages: Media Mail and First-Class Mail

“USPS may not legally pay compensation for uninsured lost or damaged articles. If your uninsured mail is missing or delayed you may request a Missing Mail Search.”

— USPS claims page, checked Oct 19, 2026

So for a Media Mail package with no bought coverage, the search is the only USPS route (Media Mail tracking and insurance). For Priority Mail Express, USPS's Missing Mail page also points to the money-back refund (Priority Mail Express refunds).

Worked example: a stalled box of books

Worked example: A 4 lb Media Mail box of books mailed Oct 1, 2026, with no tracking scans after Oct 3 and no insurance bought
Postage paid	$6.60
Missing Mail search, from (day 7)	Oct 8, 2026
Insurance claim	Not possible: Media Mail has no included coverage
Had it gone Ground Advantage: claim window	Oct 16, 2026 to Nov 30, 2026

With the search, describe the books (titles, condition, the box) and include photos; USPS sends what it finds to the address you give.

Questions

Can the buyer file a Missing Mail search?

Yes. USPS's Missing Mail page is written for mail you're sending or receiving.

Does a Missing Mail search count as a claim?

No. A claim is separate and needs insurance; if the package was insured, file the claim in its own window (how).

Can I file a search before day 7?

USPS says searches can be submitted starting 7 days from mailing.

How do I file a USPS insurance claim for a lost or damaged package?
Online at usps.com or on PS Form 1000: the window, the evidence and what happens after.
How soon, and how late, can I file a USPS claim?
The earliest and latest day to file for each service, with dates for a real mailing.
Who should file the USPS claim, the seller or the buyer?
Either can file for damage; a lost package needs the label record. And who gets paid if both file.
How much does USPS Package Intercept cost, and will it stop my package?
$19.45 only if USPS catches it, and why Media Mail comes back as Priority Mail.
