Can you use a first class stamp for international mail

In the United States, the answer is no, you cannot use a First-Class Mail stamp for international mail.

First-Class Mail stamps are only valid for mail sent within the United States, including domestic mail, priority mail, and package services. They are not valid for international mail.

For international mail, you need to use International Forever Stamps or Global Forever Stamps, which are specifically designed for sending mail to other countries. These stamps have a higher value than First-Class Mail stamps and are required to cover the cost of international postage.

Here are some key differences between First-Class Mail stamps and International Forever Stamps:

• First-Class Mail stamps:
  • Valid for mail sent within the United States
  • Cost: $0.55 (as of 2022)
  • Weight limit: 3.5 oz
• International Forever Stamps:
  • Valid for mail sent to other countries

  • Weight limit: 3.5 oz
• Global Forever Stamps:
  • Valid for mail sent to other countries

It's important to note that the cost of international postage can vary depending on the destination country, weight, and size of the mailpiece. You can use the USPS website or consult with a postal clerk to determine the correct postage for your international mail.
