Can you use postcard stamps for regular mail
In the United States, the answer is generally no, you cannot use postcard stamps for 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 for a standard letter.
- Adhesive: Postcard stamps are designed with a special adhesive that is meant to stick to the postcard, not to a standard envelope. Regular mail requires a stamp with a more robust adhesive that can stick to a variety of envelope materials and sizes.
- 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 an envelope.
That being said, there are a few exceptions:
- If you're mailing a letter that weighs less than 1 ounce and is going to a destination within the United States, you can use a postcard stamp. However, you'll need to make sure the letter fits within the postcard's dimensions (3.5 inches x 5 inches) and is not thicker than 0.007 inches.
- If you're mailing a letter internationally, you may be able to use a postcard stamp, but you'll need to check the specific postage requirements for the destination country.
In general, it's best to use stamps specifically designed for regular mail to ensure your letters are properly stamped and delivered.
