Can I use letter stamps as postcard stamps?
I was wondering if I can use letter stamps as postcard stamps?
Yes, you can use letter stamps for postcards as long as the weight and size of the postcards meet the requirements for the letter stamp. A standard letter stamp is meant for letters that weigh up to 1 ounce and measure up to 11 inches in length, 6 inches in height, and 0.25 inches in thickness. Postcards typically meet these requirements, so you should be fine using a letter stamp.
