Does the Post Office Have an Online Postage Calculator?
Yes, they do. It’s available here: USPS Postage Price Calculator. Around May of 2017 the calculator was updated to try and make it easier to use, but, WOW, for calculating postage for letters/envelopes it became MUCH more difficult to use. For example, every person using the calculator sees two checkbox option about shipping live animals or day-old poultry. I wonder how many people that message applies to? But, yes, what do you expect: it’s a government-created web site 🙂 All kidding aside, other than being a bit complex, once you’ve been through it a few times it works quite well for Priority mail and packages. If you are looking up the price for a letter, on the first screen, make sure you select the icon titlted “Calculate price based on Shape and Size”.
How much does it cost to mail a postcard?
In 2023 the cost to mail a standard size postcard is 51 cents ($0.51). The postcard can be no larger than 6 inches by 4.25 inches. The United States Postal Service offers “Postcard Forever Stamps”. An oversized postcard (no larger than 11.5×6.125 is $0.58 (note: this rate needs to be verified following 7/9/2023 increase)
Do Forever Stamps Expire?
Forever Stamps never expire and will always be the equivalent value of whatever the corresponding postal rate is – for example, a one-ounce First Class stamp for a regular Forever Stamp (that’s why I created this site: to keep track of the current postage rate which regular changes).
The Post Office offers a variety of Forever Stamps: Regular (one ounce), Additional Ounce Forever Stamp, Two Ounce Forever Stamp, Three Ounce Forever Stamp, Non-Machinable Surcharge Forever Stamp (would be used for odd sized letters), Postcard Forever Stamp, and the Global Forever Stamp.
