Shipments can sometimes be lost during transit, including orders to your customers. How do you help customers who are reaching out for assistance? USPS provides resources to try to locate missing mail and packages, and the USPS Mail Recovery Center serves as the hub for lost items. We also have tips to prevent packages from going missing in the first place. If you’re feeling lost about lost packages, you’ve found the right blog.
As we mentioned earlier, the USPS Mail Recovery Center acts as a centralized location for lost mail and packages. All packages and mail are examined upon arrival. If packages or envelopes are deemed valuable (over $25 in merchandise or over $20 in cash), they will be opened by USPS personnel to try to reunite the items with their sender or recipient. Mail with a barcode will be kept for 60 days, and mail without a barcode will be kept for 30 days. After this time frame, items will be donated, thrown away or recycled, or auctioned off.
USPS offers free resources to try to track down missing mail and packages. The first step is to track your package, followed by submitting a couple of different forms. This process is designed to give USPS detailed information about your package to hopefully increase the chance of it being found.
The first step is to track your package. It might seem straightforward, but checking the tracking details of your shipment might show where/if the package was disrupted in transit. The tracking information will also show delays or if a package is being held at the post office for pickup. We recommend taking screenshots or writing down the tracking information shown because USPS may ask for this information later on.
If entering the tracking information doesn’t provide answers, fill out a missing mail search form. This form will ask for your shipment’s tracking number, carrier service, and other attributes. Be as specific as possible and answer as many questions as you can.
After tracking your shipment and completing the missing mail search form, wait seven business days. If your package still hasn’t reached its destination, you’ll fill out a missing mail search request. USPS does require you to create an account to access the form, but account creation is free. The missing mail request will ask questions about the contents of your package as well as the packaging used and any identifying details. USPS also recommends sending pictures of your shipment if possible.
Once you’ve submitted a missing mail search request, check for a confirmation email from USPS; updates will also be sent via email. Recovered mail will be sent to its destination. However, if a package is deemed unsafe, it won’t be eligible to move forward in transit. It’s also important to note that some packages are unable to be found.
If your package is unable to be recovered or you used a guaranteed service and/or a service with included insurance, you can:
Priority Mail® and Priority Mail Express® each include $100 of insurance for eligible shipments. This insurance doesn’t come with an additional cost and is a benefit of using the services. If your package is lost or damaged, you can send a claim to USPS for potential reimbursement. To file a claim with USPS, you’ll need to create a free account. Additionally, confirm your claim is being filed within the following timeframes:
*Note: Claims should be filed before 60 days.
Lastly, collect all of the documentation listed by USPS before submitting your claim. This way, you can fill out your claim and help prevent having to resubmit information. If you’re filing a claim for a customer, let them know to keep all of the packaging and information they have until USPS resolves your claim. USPS outlines the documentation needed to file a claim we’ve included below, and additional information can be found on their website.*
*Note: This information is directly from the USPS website, so we recommend reaching out to USPS with any questions.
Tracking or Label Number
Evidence of Insurance Purchased
NOTE: 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.
Proof of Value
Proof of value is the cost or value of an item when it was mailed. Any of these can be used to show proof of value:
Proof of Damage
Photos that clearly show the extent of damage will help with your case. For damaged claims, you’ll also need to provide an estimate of the repair costs from a reputable dealer.
Another way to decrease the risk of lost packages is with delivery confirmation. Delivery confirmation comes at no additional cost when using Priority Mail®. This feature provides information about the time, date, and zip code of when the package was signed for. Also, delivery confirmation will show a delivery attempt if your package couldn’t be delivered.
To add delivery confirmation on Stamps.com Online:
Select the Tracking drop-down menu under the Mail Tab of your dashboard and click Signature Required.

To use delivery confirmation with Stamps.com PC Software:
Once you select the mail class for your package, go to the Packages Tab on your dashboard. For shipments using Priority Mail Express®, click the Delivery Options button and select Signature Required.

If you’re using another service, select the Tracking drop down menu and then click Signature Confirmation.

Delivery confirmation information is available for up to a year after the delivery date. You can receive a copy of your recipient’s address by calling USPS at 1-800-222-1811 on Monday through Friday from 8:00 AM to 8:30 PM ET. Signatures can be mailed, faxed, or emailed to you directly. Mail requests are sent through First-Class Mail® and are usually delivered within 2-3 business days. Fax requests are typically completed within two hours and can be received 24/7.
If your package or letter hasn’t arrived, use this process to search for your missing USPS mail and increase your chances of recovery.
Check your tracking number in your Stamps.com account or at USPS.com. This may reveal where the package was last scanned or marked.
If the tracking status doesn’t answer your question, fill out the USPS missing mail search form. Provide your tracking number, service type, and detailed information about the item.
Wait seven business days after mailing. If your item hasn’t arrived, fill out a Missing Mail Search Request using the tracking number, mailing date, package description, and any photos you might have.
Check your email for updates from USPS. Recoveries are sent out once the search resolves. If your item cannot be located, you may proceed with a claim if applicable.
