Safety answer: No single photograph, color difference, perforation, seller claim, or price can reliably authenticate every postage stamp. Use official risk signals to assess a transaction, and report suspected counterfeit postage to the U.S. Postal Inspection Service rather than trying a test mailing.
Official Counterfeit-Postage Warning Signs
The U.S. Postal Inspection Service warns consumers to be cautious when stamps are offered at substantial reductions from their represented value, especially through unfamiliar online sellers or third-party marketplaces. Other reasons for scrutiny include a seller with little verifiable history, unclear sourcing, inconsistent packaging, or claims designed to create urgency without providing accountable business information.
A warning sign is not the same as proof that one physical stamp is counterfeit. Price should prompt due diligence, not a remote verdict.
What Visual Checks Can and Cannot Tell You
Comparing print sharpness, lettering, die cuts or perforations, paper, adhesive, tagging, and design details with reliable references may reveal an obvious inconsistency. However, photographs can change color and scale, genuine issues use different production methods, and counterfeiters can imitate visible details. A visual check can identify concerns; it cannot guarantee authenticity.
| Check | Useful for | Not sufficient for |
|---|---|---|
| Seller and source | Assessing transaction risk and accountability | Authenticating each stamp by itself |
| Price comparison | Recognizing an unusually large reduction as a warning signal | Proving a stamp fake solely because it is inexpensive |
| Photo or visual comparison | Finding obvious mismatches that deserve further review | Certifying an item remotely |
Crossed-Out FOREVER in Online Images
A line through FOREVER in a catalog or promotional image is commonly added to make copying the image harder. It is not, by itself, evidence that the advertised issue is expired or counterfeit. The promotional-image treatment should not be confused with the physical stamp. Read the focused guide on why FOREVER is crossed out in stamp images.
What to Do With Suspected Counterfeit Postage
- Do not use it for a test mailing. Using counterfeit postage can create legal and delivery consequences.
- Preserve the evidence. Keep the item, packaging, receipt, listing URL, seller messages, payment record, and clear photographs.
- Contact the seller or payment provider through documented channels when appropriate.
- Report the matter to USPIS. Use the official U.S. Postal Inspection Service reporting page and follow its current instructions.
Retailer Transparency and Authentication Limits
This website can explain general warning signs and identify the products it lists, but it cannot authenticate an individual stamp from a customer-supplied photo. The independent-retailer statement below explains business identity; it is not third-party proof of authenticity for a particular item.
Frequently Asked Questions
Can I identify a fake Forever stamp from a photo?
A photo can reveal concerns, but it is not a reliable basis for guaranteeing authenticity. Lighting, resolution, compression, and legitimate production differences limit remote visual checks.
Does a low price prove that stamps are counterfeit?
No. A substantial reduction can be an official warning sign that deserves scrutiny, but price alone does not authenticate or condemn an individual stamp.
Does crossed-out FOREVER in a product image mean the stamp is fake?
No. That treatment is commonly used on promotional images to hinder copying. See the crossed-out FOREVER guide.
What should I do with suspected counterfeit postage?
Stop using it, preserve the item and transaction records, and follow the current instructions on the official USPIS reporting page.
Can this website authenticate an individual stamp?
No. This page provides general risk education and official reporting links, not remote authentication or a certificate for an individual item.
