What is the postage for USPS Greeting Cards?

Created:   |   Updated:

When you are sending greeting cards through USPS, a typical greeting card can be mail for the cost of one stamp. The current cost of a 1 oz First-Class Mail stamp is $0.55 if purchased at the Post Office. Find the cost of higher weight cards.

Besides weight of the card, there are a couple of potential charges that might affect the price of your postage:

  • non-machinable surcharge
  • “rigid” letter-size pricing

What is a non-machinable surcharge?

The non-machinable surcharge applies to letter-sized greeting cards that cannot be processed automatically. Typically, this describes greeting cards weighing more than 1 ounce, up to the 3.5–ounce maximum weight.

The non-machinable surcharge criteria applies to all First-Class Mail letters.

NOTE: Current as of January 2019, USPS non-machinable surcharge for First Class Mail is $0.15. Cards sent as "large envelope/flat" are not subject to the non-machinable surcharge. Learn more.

How are “rigid” letter-size greeting cards priced?

Greeting cards can be classified as “rigid” if it cannot bend and is less than:

  • 11-1/2" x 6-1/8" x 1/4" thick 
  • 3.5 ounces

If they meet these conditions, they will be charged the standard postage rate, plus a non-machinable surcharge. You can find out more about how USPS determines flexibility by referring to their guide.

If they exceed these dimensions, they will be priced as a "large envelope/flat". Learn more.

Can I send an oversized greeting card as a standard letter?

When your greeting card is too large, you may choose to fold it gently and seal it with a wafer glue, sealing glue, or tape. To avoid mailing issues, be sure that the adhesive doesn’t interfere with the barcode or mailing address and that it falls within the acceptable sizes for folded self-mailers: 4-1/4” x 6” up to 6-1/8” x 10-1/2”.

Also be sure that the card weight and dimensions are within the limits of USPS letters. Learn more about letter dimensions.
