Postage Stamps vs Forever Stamps: What’s the Difference?

The difference is simple: a Forever stamp keeps working no matter how rates rise, while a regular stamp is locked to a printed value. Here’s the full picture and which one you should buy.

What a Forever Stamp Is

A Forever stamp covers one standard First-Class letter (up to one ounce), today and in the future. When the USPS raises rates, your Forever stamp automatically covers the new price — no extra postage needed.

• Face value today: $0.82 (since July 12, 2026)
• Never expires
• Best for everyday letters and future-proofing

What a Regular (Denominated) Stamp Is

A denominated stamp has a specific value printed on it, such as $0.40 or $0.82. If the First-Class rate rises above that value, you have to add extra postage to make up the difference.

• Fixed value
• May need additional stamps after a rate hike
• Still valid — just less convenient for mailing

Which One Should You Buy?

For mailing letters today and later, Forever stamps are the safer, simpler choice. You buy once and never worry about future rate increases.

Denominated stamps still have their place — mainly for collectors, or when you need a specific value to hit an exact postage amount for heavier mail.

Can You Use Old Stamps After a Rate Increase?

Yes. All unused USPS stamps remain valid forever. The only catch: a denominated stamp stays at its printed value, so if the rate has gone up, you’ll need to add postage.
