“USPS tracking is not available” means the USPS tracking system has no scan record it can show for that number yet. Usually the label exists but USPS hasn’t scanned the package into its network, the number was entered incorrectly, or the tracking database is briefly lagging. It rarely means the package is lost, and most cases clear within a day of drop-off.
If you no longer have the tracking number at all, see USPS tracking number customer service. To contact USPS about this error, use USPS tracking support.
What Does “USPS Tracking Is Not Available” Mean?
The message appears when you enter a number at USPS.com, in the USPS app or by text and USPS can’t return any status for it. USPS creates the tracking record when a label is made, but the first meaningful event comes only when the package is physically scanned. Until then, the system either shows nothing at all or a pre-shipment status.
Several similar messages mean slightly different things. Knowing which one you see tells you whether to wait, recheck the number or contact the sender.
| What you see | What it means | What to do |
|---|---|---|
| Status Not Available / no record found | USPS can’t find any event for this number | Recheck the number, then retry later |
| Shipping Label Created, USPS Awaiting Item | A label exists, but USPS doesn’t have the package yet | Ask the shipper when it was handed to USPS |
| Pre-Shipment Info Sent to USPS | The sender’s system sent label data; no physical scan yet | Wait for the acceptance scan |
| On Its Way to USPS / Picked Up by Shipping Partner | Another company is moving it to USPS first | Check with the shipper; a delivery date appears once USPS receives it |

Why Is USPS Tracking Not Available for My Package?
There are a handful of common causes, and most of them resolve on their own.
- The package hasn’t been scanned yet. A label printed today may not be handed over until tomorrow. Items dropped in a collection box or left for a carrier are scanned only when they reach the Post Office or a processing plant.
- The number is mistyped. One transposed digit returns no result. Domestic USPS tracking numbers are usually 20 to 22 digits starting with 9, and international ones are 13 characters ending in “US.”
- The barcode couldn’t be read. A faint, wet, wrinkled or taped-over barcode may skip machine scans, so events appear only when someone keys the number in by hand.
- The item isn’t trackable. USPS says First-Class Mail letters, flats and postcards don’t include tracking unless an extra service such as Certified Mail was added.
- A shipping partner has it. Some retailers use a partner company that delivers parcels to USPS for the final mile. USPS can’t show a status until the handoff.
- The tracking system is lagging. During heavy volume or maintenance, events can post hours late even though the package keeps moving. Our page on USPS tracking being down explains how to tell a site problem from a package problem.
- The record has expired. USPS keeps standard tracking records for 120 days. Older numbers stop returning results.
How Long Does “Tracking Not Available” Usually Last?
For a newly created label, allow about 24 hours after the package was actually handed to USPS before you worry. A pre-shipment status can sit for days if the sender simply hasn’t shipped yet, and that is a question for the sender rather than USPS.
Once a package has been scanned, gaps of a day or more between events are normal while it travels between facilities. USPS lets you submit a Missing Mail search starting 7 days after the mailing date, which is a useful marker for when waiting stops being reasonable.
How Do You Fix USPS Tracking Not Available? 7 Fixes
Work through these in order. The first three solve most cases in minutes.
1. Re-enter the Tracking Number Carefully
Copy the number from the receipt or label rather than retyping it, and remove spaces and dashes. Watch for look-alike characters in international numbers, such as O and 0. If USPS still says the number is invalid, our guide to a USPS tracking number not working covers format checks.
2. Wait 24 Hours After Drop-Off
If you dropped the package off after the last collection time, or put it in a collection box, it may not be scanned until the next business day. Check again the following afternoon before taking any other step.
3. Try Another USPS Channel
The USPS website, the USPS Mobile app and text tracking (send the number to 28777) all read the same record, but a site issue can affect one channel and not another. Clearing your browser cache helps when the page shows stale results. Our roundup of ways to track a USPS package lists each option.
4. Ask the Sender Whether It Has Shipped
If you’re the recipient and see “Label Created” or “Pre-Shipment,” USPS says it doesn’t have the item yet and directs you to the shipper. Many online stores print labels before the package is packed or picked up.
5. Confirm Your Receipt Shows an Acceptance Scan
If you mailed the package at a Post Office counter, your receipt should show the tracking number and the acceptance. If you need proof that USPS took it, ask the retail associate to scan the package in front of you next time. If tracking stalled after a drop-off, see USPS tracking not updating after drop off.
6. Sign Up for Updates or Informed Delivery
Request text or email alerts on the USPS Tracking results page so you hear about the first scan without rechecking. Recipients enrolled in Informed Delivery can also see tracked packages addressed to them in one dashboard.
7. Submit a Help Request or Missing Mail Search
If there’s still no status well beyond the service’s delivery range, file a request through USPS. A USPS Missing Mail search can be submitted from 7 days after mailing, up to 365 days.
Does “Not Available” Mean Your Package Is Lost?
Usually not. A missing status tells you about the tracking record, not where the package is. Packages often move several facilities between scans, and an unscanned label can still be delivered normally with a single “Delivered” event at the end.
It’s worth acting sooner when the item was sent Priority Mail Express, which carries a money-back delivery guarantee, or when the contents are perishable or time-sensitive. In those cases, keep your receipt and contact USPS once the guaranteed date passes. For a broader look at stalled updates once tracking has started, see our complete USPS tracking guide.
How Can Shippers Prevent Tracking Gaps?
Most gaps start at the label. A few habits make the first scan more likely to happen on time.
- Place the label flat on the largest surface, away from box seams and edges.
- Print with enough toner that the barcode is crisp, and keep the label dry.
- Don’t cover the barcode with glossy or wrinkled tape that can cause glare or distortion.
- Hand packages to a Post Office counter or a scheduled pickup rather than a collection box when you need a same-day acceptance scan.
- Keep receipts and label records until the package is delivered.

Frequently Asked Questions
Why does USPS tracking say not available right after I mailed something?
USPS tracking is not available until the package receives its first physical scan. Items dropped in a collection box or handed over after the last collection time are often scanned the next business day. Wait about 24 hours after drop-off, then recheck the number before contacting USPS.
Can a package be delivered if tracking is not available?
Yes. A package with an unreadable or skipped barcode keeps moving through the mail and can be delivered normally. Sometimes the only event that appears is the final “Delivered” scan, or a scan entered by hand. The missing status reflects the tracking record, not the package itself.
Why does USPS tracking say not available for my letter?
USPS doesn’t include tracking with First-Class Mail letters, flats or postcards. Unless the sender added an extra service such as Certified Mail, there is no tracking number for that item. Informed Delivery can show a scanned image of incoming letter mail, but not a tracking history.
When should I file a Missing Mail search?
USPS accepts Missing Mail search requests starting 7 days after the mailing date and up to 365 days after. Before filing, confirm with the recipient or sender that the item hasn’t arrived, and gather the tracking number, mailing date, addresses and a description of the package and contents.
How long does USPS keep tracking information?
USPS keeps standard tracking records for 120 days. Signature Confirmation records are kept for one year, and Priority Mail Express, Certified Mail and Registered Mail records for two years. After those periods a number may show “not available” even though the item was delivered.
