A Global Forever stamp is a USPS nondenominated stamp for qualifying international First-Class Mail. As of August 31, 2026, one Global Forever stamp is worth $1.75 and covers a standard one-ounce First-Class Mail International letter or eligible postcard to a country where that service is available. Genuine unused Global Forever stamps remain valid when prices rise.
How Global Forever Stamps Work
The stamp follows the current price of a one-ounce First-Class Mail International letter rather than displaying a fixed denomination. You buy it at the current price and can use it later for the same qualifying mail category without adding postage solely because the rate increased.
| Mailpiece | Does one Global Forever stamp cover it? | What to check |
|---|---|---|
| Standard international letter, 1 oz. or less | Usually yes | Destination availability, dimensions, shape and machinability |
| Eligible international postcard | Usually yes | Postcard dimensions and destination availability |
| Letter over 1 oz. | No | Add postage for weight and destination price group |
| Square, rigid or unusually shaped letter | Not necessarily | Nonmachinable or other applicable charges |
| Package or merchandise shipment | No automatic one-stamp rule | Use the correct international package service and customs requirements |
Are Global Forever Stamps International Stamps?
Yes. They are designed around the one-ounce First-Class Mail International letter price. “Global” does not mean every item can be mailed anywhere for one stamp: the destination must accept the service, and the mailpiece must meet the category’s weight, size, shape and content rules.
Do Global Forever Stamps Expire?
No. A genuine unused Global Forever stamp keeps the postage value of the current one-ounce First-Class Mail International letter rate. Damage, prior use or counterfeit postage is not valid postage.
Can You Use Regular Forever Stamps for International Mail?
Yes, ordinary domestic Forever stamps can be combined to reach the required international postage. At current values, three 82-cent ordinary Forever stamps total $2.46, which is more than the $1.75 one-ounce international letter price. Extra postage is not refunded, so a Global Forever stamp is usually the simpler choice for a qualifying letter.
Can You Use a Global Forever Stamp in the United States?
It can contribute its full current postage value to eligible domestic mail, but using one on an ordinary one-ounce domestic letter currently overpays the 82-cent rate. Match the stamp to the mail category when possible.
Before Mailing Internationally
- Confirm the destination currently accepts First-Class Mail International.
- Weigh and measure the finished mailpiece.
- Check whether the shape, rigidity, contents or thickness changes the price or service.
- Use additional postage or a different service when the piece is heavier or is a package.
