Direct answer: An ordinary Forever stamp can pay toward eligible U.S. domestic mail from any state, including New York and Hawaii. Puerto Rico, Guam, the U.S. Virgin Islands and military APO/FPO/DPO addresses use U.S. domestic postal treatment for many ordinary letter mailings, but the finished mailpiece, destination format, customs rules and requested service can change what is required.
Direct Destination Answers
| Destination | Can an ordinary Forever stamp be used? | Important limit |
|---|---|---|
| Any of the 50 states, including New York and Hawaii | Yes. | One stamp is sufficient only for an eligible domestic one-ounce letter. |
| District of Columbia | Yes. | Normal domestic mailpiece rules apply. |
| Puerto Rico and U.S. Virgin Islands | Yes, for eligible domestic mail. | Packages or contents can trigger additional forms or rules. |
| Guam and other U.S. territories served as domestic mail | Yes, for eligible domestic mail. | Verify the exact destination and mailpiece with USPS. |
| APO, FPO and DPO | Yes, valid U.S. postage can be used. | Use the required military address format and check content restrictions. |
| Foreign country | Yes only as part of international postage. | An ordinary Forever stamp alone usually does not meet the international rate. |
Do Forever Stamps Expire in New York or Another State?
No. A genuine unused ordinary Forever stamp does not expire because it is used in a particular state. What changes the required postage is the mailpiece and service, not the state where the stamp is used.
Why One Forever Stamp May Still Be Insufficient
Extra weight, a square or rigid envelope, a large envelope, a package, an international destination or an added postal service can require more postage. Check the finished piece rather than relying only on the address.
