How to verify the Forever Stamps you buy in bulk are genuine

Counterfeit stamps are a real problem in the discount postage market. USPS Inspector General seizures have increased as fake sheets and rolls, many shipped in from overseas, get sold through marketplace listings at prices that look too good to be true. Sometimes they are. If your mail carries a fake stamp, USPS can seize the mailpiece and the sender can face follow-up, so the cheapest stamp on the internet can turn out to be the most expensive one you ever bought.

Here is how buying teams we work with check stock before committing to a supplier.

Compare against a known-genuine stamp

The fastest check costs nothing. Put a stamp from the lot next to one bought at a Post Office window and compare them side by side. Counterfeits usually fail on print quality: the flag detail goes soft, colors sit slightly wrong, and fine linework fills in. Genuine US stamps are printed on high-security presses and the difference is visible under good light, or under a loupe if you have one.

Check the physical details

• Paper feel. USPS stamp paper has a specific weight and finish. Counterfeit paper often feels glossier or thinner.
• Die cuts. Self-adhesive stamps are die-cut with clean, consistent spacing around the edges. Ragged or uneven cutting is a red flag.
• Microprinting. Genuine stamps carry microprinted text that is hard to reproduce. Under magnification it stays crisp on a real stamp.
• Roll consistency. In a genuine roll, every stamp looks identical. Variation within one roll, subtle shade shifts from stamp to stamp, points to a copy job.

Weight and count the lot

A 100-stamp roll has a predictable weight and a predictable size. If a supplier sells “rolls” that are light, short-counted, or wrapped in packaging that does not match USPS specifications, treat it as a warning sign rather than a bargain. Count a sample roll from any first delivery, every roll if the lot is large enough to matter.

Vet the seller before you pay

The stamp in the photo is not the stamp you receive, so the seller matters more than the picture. Before paying:

• Ask where the stock comes from. Liquidation and asset-recovery lots have paper trails.
• Get the genuineness commitment in writing, on the quote or invoice, not in a chat message.
• Confirm payment instructions by phone or a second channel. Wire fraud targeting bulk-goods buyers is common.
• Start with a first order sized so a problem hurts, but does not sink you.

What we do on our side

Our stock arrives from US corporate liquidation channels, and each lot gets checked before it goes into inventory. We put the genuineness of what we ship in writing, and if a lot ever failed verification it would never reach a customer. If you want to run your own checks on a first delivery, we encourage it.
