How many stamps to mail a card

The number of stamps needed to mail a card depends on the weight and size of the card, as well as the destination. Here are some general guidelines:

Domestic Mail (within the United States)

• A standard-sized greeting card (up to 3.5 inches x 5 inches) weighing up to 1 ounce: 1 first-class stamp ($0.55)
• A standard-sized greeting card weighing 1-2 ounces: 2 first-class stamps ($1.10)
• A standard-sized greeting card weighing over 2 ounces: additional ounces are charged at $0.15 each

International Mail

• A standard-sized greeting card weighing up to 1 ounce to Canada or Mexico: 1 international first-class stamp ($1.20)
• A standard-sized greeting card weighing up to 1 ounce to other countries: 1 international first-class stamp ($1.20)
• A standard-sized greeting card weighing over 1 ounce to any country: additional ounces are charged at $0.20 each

Special Considerations

• If your card is larger or heavier than a standard greeting card, you may need to use a larger envelope or a package rate stamp.
• If you're mailing a card to a military address or a U.S. territory, you may need to use a special rate stamp.
• If you're mailing a card to a country that requires a customs form, you may need to use a priority mail international stamp.

Tips

• You can use a postage scale to weigh your card and determine the exact postage needed.
• You can also use a postage calculator or consult with a postal worker if you're unsure about the correct postage.
• It's always a good idea to affix the correct postage to your card to avoid delays or additional fees.
