Unclaimed mail packages help you peer into a world of undelivered consumer goods, offering surprise and potential resale value. What did they order? Who knows! That’s the fun in purchasing returned unclaimed packages – you never know what you’ll get when you buy unopened packages full of mystery.

I’m seeing resellers do a lot of interesting things with their mail packages:

• Open them on Whatnot
• Go on TikTok Live to open them live
• Live stream opening the packages on Facebook, Instagram and YouTube

Armies of sellers are purchasing these mail packages wholesale and flipping them to make a profit. You can follow in their footsteps to resell items, or you can opt to keep some for yourself. I know that I’ve kept more than a few valuable items that were originally deemed undeliverable by carriers.

Even the Chromebook that I’m writing this on was in an unclaimed package.

Unclaimed mail packages typically originate from postal and courier services like USPS, FedEx, UPS, or Amazon returns, where packages become undeliverable and unclaimed after repeated delivery attempts. These parcels are sold in bulk through liquidation companies or auction platforms.

You can have a lot of fun and make some good money if you know where to look. I’m going to share 9 reliable liquidation companies selling these packages to help you get in on the fun and excitement, too.

What are unclaimed mail packages?

Unclaimed mail packages are parcels that can’t be delivered as addressed. Any package that is undeliverable and unclaimed for 90 days is fair game for resellers and anyone else to buy. You can find both single and bulk undelivered packages for sale.

How to get unclaimed mail packages?

To get unclaimed mail packages, start by exploring online auction sites and postal surplus auctions where these items are sold. They often come in mystery boxes or bulk lots, so the contents are usually unknown. It’s important to check the auction details and seller ratings before making a purchase.

How do I avoid scams when buying unclaimed mail packages?

Resellers see discounted items like these and pounce on them because the deals are almost too good to be true. But scammers do exist, and they can sell you packages that are always broken or not send the packages.

You can avoid scams by doing a few things;

• Read reviews about the seller
• Ask customer service questions
• Purchase a small package to test the waters

Performing your own due diligence online will help you narrow down your list of potential suppliers. I did conduct my own research into the liquidation companies above to make your choice easier and safer.

Where do unclaimed packages come from?

Daily, USPS handles over 23.5 million packages. Most reach their final destination, but many do not. Undeliverable items go through a process where the carrier tries to deliver them following procedures, but then they end up being sold to liquidation companies in bulk.

Imagine all of the packages UPS, FedEx, DHL and other shipping companies cannot deliver.

Each of them sells unclaimed packages, especially when there are no return addresses, because they don’t know who to return the items to in the first place.
