Introduction

Did you get a message from USPS saying that they attempted delivery but your package was undeliverable? This doesn't necessarily mean your package is lost or can no longer be delivered. It simply means USPS couldn't deliver it to the address provided. When this happens, USPS generally returns the package to the sender, who can then ship it again. Track your package to check for updates from USPS. You may also be able to schedule a redelivery if the address is correct. Continue reading for instructions on what to do when your package can't be delivered.

Track Your Package

Use the USPS Tracking page to track your package. Enter your tracking number or barcode number in the field and click Track. You can enter up to 35 tracking numbers to track multiple packages at once. You can find your tracking number on your shipping receipt, sales receipt, confirmation email, or the peel-off portion at the bottom of your shipping label.

If the tracking status says Insufficient Address or No Such Number, this means the package will be returned to the sender. When it says only "no access to the delivery location," it means the delivery rider couldn't reach your porch or mailbox. You don't need to do anything, as USPS will reattempt delivery the next day.

When your package can't be delivered, check whether redelivery is possible. Proceed to the next step to learn how to check if your package is eligible for redelivery.

What Do I Do If I Get a Note That Post Office Attempted Delivery, Package Is Undeliverable as Addressed from the Usps? (Step 1)

Check Redelivery Availability

If the package hasn't been returned to the sender yet, USPS may be able to redeliver it. First, check whether redelivery is available at your address. To check availability, visit the USPS Redelivery page and enter the required information, including your complete address. Fill out the form and click Check Availability.

To schedule a redelivery, use the barcode or tracking number USPS provides. Just follow the instructions to complete your request, or contact USPS for more information.

Note: Before requesting a redelivery, confirm that the delivery address is correct.

Visit Your Local Post Office

Undelivered packages may still be held at your local post office for a few days before they're returned to the sender. Track your package first to see if USPS has any instructions. Then, visit your local post office to claim your package if it's available for pickup. Don't forget to bring a valid government-issued ID and your tracking number.

To find a USPS location, enter your ZIP code or city and click Search. You can also click Use Current Location to find the nearest post office in your area.

To ensure you receive important updates about your package, we suggest signing up for USPS Informed Delivery. If you live in an eligible ZIP code, you can sign up for this service to view delivery details and, if available, schedule a redelivery. By enabling package-tracking notifications, you can receive email or text alerts about your package's status. To sign up, visit the USPS Informed Delivery page and follow the instructions.

Why does GetHuman Write How-to Guides for US Postal Service Problems?

GetHuman has been working for over 10 years on sourcing information about big organizations like Comcast in order to help customers resolve customer service issues faster. We started with contact information and fastest ways to reach a human at big companies. Particularly ones with slow or complicated IVR or phone menu systems. Or companies that have self-serve help forums instead of a customer service department. From there, we realized that consumers still needed more detailed help solving the most common problems, so we expanded to this set of guides, which grows every day. And if you spot any issues with our What do I do if my Xfinity TV or internet is out? guide, please let us know by sending us feedback. We want to be as helpful as possible. If you appreciated this guide, please share it with your favorite people. Our free information and tools is powered by you, the customer. The more people that use it, the better it gets.
