Where and how to buy Forever Stamps
- USPS.com is the most reliable source for current pricing and delivery details
- Retail locations including post offices, grocery stores, and pharmacies

Common questions about Forever Stamps
- Do Forever Stamps expire? No; they remain valid for mailing a 1 oz letter indefinitely.
- Are older Forever Stamps still valid? Yes, as long as they are stamped Forever and purchased for First-Class letter postage; they retain the ability to cover the 1 oz letter rate even after price changes.
- What if I have older stamps and prices rise? You do not need additional postage; a Forever Stamp always covers the 1 oz letter rate regardless of when it was issued.
- Can I use multiple Forever Stamps for heavier letters? Technically yes, but it is inefficient; Extra Ounce or Additional Ounce stamps are more cost-effective for letters over 1 oz.
- Are Forever Stamps the same as Additional Ounce stamps? No; Additional Ounce stamps apply only to each extra ounce beyond 1 oz and are priced differently.
