How Many Stamps Do I Need to Mail a Card to Mexico?

To determine how many stamps you’ll need to mail a card to Mexico, you’ll need to know how much your card weighs.

Most standard-sized* cards weigh less than 1 ounce, meaning that you’ll only need one Global Forever stamp for mailing.

Like domestic Forever Stamps, the global version will always have the postage value equivalent to the price of a single First-Class International letter at the time of use.

Put another way, Global Forever stamps will always cover the cost of sending a 1 ounce letter or card to Mexico, even if postage increases.

While Global Forever stamps are the easiest way to send cards to Mexico, you can use domestic Forever Stamps, as long as their value adds up to $1.30.

At the current rate ($0.58), you’d need 3 domestic Forever Stamps to cover postage to Mexico.

This is not recommended, as you’d pay $1.74 to mail your card, which is $0.44 more than you need to.

*USPS defines standard-sized letters as those meeting the following criteria:

  • Rectangular
  • At least 3 ½ inches high x 5 inches long x 0.007 inch thick
  • No more than 6 ⅛ inches high x 11 ½  inches long x ¼  inch thick

Such pieces are sent via USPS’ First-Class Mail International Service.

First-Class Mail International Service covers letters, postcards, and envelopes weighing up to 3.5 ounces.
