Sending Postcards with USPS

What is a Postcard?

A postcard is a rectangular mailer sent without an envelope. Sending a postcard is an extremely affordable way to communicate when you’re using the U.S Postal Service—regular postcards cost only $0.34 to mail!

To qualify for postcard pricing, your mailer must be at least 3 ½” high, 5” long and 0.007” thick (approximately the thickness of an index card), but no more than 4 ¼” high, 6” long, or 0.016” thick. To qualify for the base rate, postcards cannot be folded. Large postcards can measure up to 6 and 1/8” high, 11 ½” long and ¼” thick, but they cost as much as a First-Class Letter ($0.48 and up) to send.

Business postcards generally have an image or call to action on the front, with space on the back for the delivery address, postage and perhaps a short message. Common examples include appointment reminders, sale or grand opening announcements, and real estate listings. They provide an easy and affordable way to market your products and services to customers, and they are also an inexpensive option when sending out holiday cards.
