What Should I Do if My Mail is Missing?
It’s always important to you and the USPS when you send or receive mail. If your mail is missing, you can follow the steps below:
1. Check the Current Status
Make sure to use USPS Tracking if your mail or package has a tracking number.
This will inform you about the current status of your mail or package.
2. Complete a Help Request Form
The request form is the first step to let your local Post Office be aware of the issue and begin the search process.
Complete an online assistance request form using either a desktop computer or a mobile phone.
3. Submit a Missing Mail Search Request
If, after waiting for 7 business days from your online help request submission, your mail or package remains missing, it’s time to submit a Missing Mail search request.
Provide the following details:
- Sender’s mailing address
- Recipient’s mailing address
- Size and type of container or envelope used
- Identifying information, such as USPS Tracking number(s), mailing date from your receipt, or Click-N-Ship label receipt
- A detailed description of the contents, including its nature, brand, model, color, or size, if applicable
- Include any pictures that might assist in identifying your item
4. USPS Mail Search
USPS will send you an email to confirm they got it after you submit your Missing Mail search request. If your package or mail is located, they will be sent to the address provided.
However, it’s essential to know that there are situations where they may not be able to find or send missing mail due to safety concerns.
5. Additional Information
You can request a refund when using a service like Priority Mail Express, which has a money-back guarantee.
Begin a claim quickly if you notice damaged or missing contents. Make sure it is done no later than 60 days from the mailing date.
What’s the USPS Mail Recovery Center?
The USPS Mail Recovery Center serves as a central hub for lost mail and packages. When items arrive, they are inspected.
If a package or envelope is considered valuable (worth more than $25 in stuff or over $20 in cash), USPS workers will open it to try to send it back to the sender or recipient.
Mail with a barcode is stored for 60 days, while mail without a barcode is kept for 30 days. After this period, items may be donated, discarded, recycled, or auctioned.
Possible Causes of Lost USPS Packages
There are several potential reasons why USPS packages may become lost:
1. Incorrect Address
Delivering the package to the wrong location is certain if the sender provides an incomplete or wrong address, or if there is a mistake during data entry.
2. Illegible Label
An unclear and damaged label can also contribute to your package being lost in transit. It is also advised you use a clear label to avoid this issue.
3. Weather or Natural Disasters
Severe weather conditions, like storms, hurricanes, or floods, can disrupt normal postal operations and lead to losses.
4. Stolen Package
Thieves can sometimes steal packages during transit or after delivery.
5. High Package Volume
This issue can also arise during peak seasons or holidays. When there is a rush in package volume, there may be a higher likelihood of processing errors or delays.
Tips to Prevent Lost USPS Packages

There are valuable tips to help you avoid the frustration of lost packages:
1. Confirm Address
Always take a moment to confirm the recipient’s address, especially if they live in a shared space. An accurate address is needed to ensure successful delivery.
2. Consider Extra Insurance
Consider purchasing additional insurance if you’re shipping expensive items like jewelry or electronics. This gives you added protection in case anything goes wrong during transit.
3. Track Packages
Enable tracking notifications for your shipments. With the notification, you were informed about the package’s location and time of delivery.
4. Use Inner Labels
Include labels inside the package in addition to the outer label. This is helpful in case the outer label becomes damaged or unreadable during transit.
5. Secure Labeling
Do well to write the address clearly and legibly when labeling. Strong tape covers and prevents labels from getting damaged during handling and transportation.
USPS Missing Mail Search ensures the safe delivery of your mail. It helps locate and recover your missing items if your mail is lost or delayed.
