Can you use postcard stamps on regular mail
In the United States, the answer is generally no, you cannot use postcard stamps on regular mail. Here's why:
- Denomination: Postcard stamps are typically designed for a specific denomination, usually 35 cents or 55 cents, which is the cost of mailing a postcard within the United States. Regular mail, on the other hand, requires a stamp with a denomination that matches the current first-class mail rate, which is currently $0.55.
- Adhesive: Postcard stamps are designed with a special adhesive that is meant to stick to the postcard, not to a larger envelope. Regular mail requires a stamp with a more robust adhesive that can stick to a heavier envelope or package.
- Perforations: Postcard stamps often have perforations (small holes) along the edges, which make it easy to tear off a corner and attach the stamp to a postcard. Regular mail stamps usually don't have perforations, as they're designed to be attached to a larger envelope or package.
That being said, there are a few exceptions:
- If you're mailing a small, lightweight item (like a letter or a small package) that weighs less than 1 ounce, you might be able to use a postcard stamp. However, you'll need to make sure the stamp is affixed correctly and that the item is properly addressed and packaged.
- If you're mailing a package or envelope that weighs more than 1 ounce, you'll need to use a regular first-class mail stamp or a stamp with a higher denomination (like a Priority Mail stamp).
To be safe, it's always best to use a regular first-class mail stamp or a stamp with a denomination that matches the current first-class mail rate when mailing regular mail.
