Postcard Stamp vs. Forever Stamp

Before discussing how many postcard stamps are needed to mail a letter, let’s first understand the concepts of postcard stamps and permanent stamps.
Postcard stamps and Forever stamps are two different types of stamps issued by the United States Postal Service (USPS), each with its purpose and value.

  1. Postcard Stamps: Postcard stamps are designed for sending postcards within the United States. Postcard stamps are usually worth less than ordinary first-class letter stamps.
    The exact value of postcard stamps depends on current USPS postage rates, which may change over time. The current price of postcard stamps must be checked with the USPS or its official website.
    According to the latest news, in 2023, the price of 1 ounce of metered mail will increase to 63 cents, and the price of sending a domestic postcard will increase to 51 cents.
    A 1-ounce letter sent to another country will cost $1.50. The single-letter and peace add-on ounce price will remain unchanged at 24 cents.
    Here are USPS suggested prices:

  1. A “Forever Stamp” is a postage stamp that can mail a one-ounce (about 28-gram) letter no matter when the stamp was bought.
    The word “Forever” means that the stamp will still be worth its face value even if mail rates go up in the future. This means that if you buy a Forever stamp for a specific price, it will still mail a one-ounce letter even if mailing rates go up in the future.
    Both postcard stamps and Forever stamps are easy ways to send mail, but according to USPS rules, it’s essential to know their unique purpose and current value. Consult the USPS or their official website for the most exact and up-to-date information on stamp values and postage rates.
    Let’s find out if the stamp on a letter from the post office is a forever stamp.

Are Postcard Stamps Forever?

Are Postcard Stamps Forever

Yes. The United States Postal Service (USPS) started selling Forever stamps for postcards on May 14, 2015.
Since then, postcard stamps have been available as “Forever” stamps. This means that customers can use them to mail postcards at the current rate for sending a one-ounce letter, even if prices change in the future.
This means that even if the price of postage goes up in the future, standard-sized postcards can still be sent within the U.S. for free with Forever stamps on postcards.
So postcard stamps are forever stamps. Do you have to use postcard stamps to mail postcards?

Do I Have to Use Postcard Stamps to Mail Postcards

No, you don’t have to use postcard stamps to send postcard.
Even though postcard stamps are explicitly made for sending postcards, you can also use other ways to pay for postage.
You can use regular Forever stamps or any other stamp worth enough to cover the postage for a one-ounce letter to send a standard-sized postcard within the United States.

Postcards are charged the same amount for postage as one-ounce First-Class Mail letters.
Postcard stamps may be helpful because they are priced for postcard sending, but you don’t have to use them.

You can pay for postage with a mix of regular stamps and other values as long as the amount of postage on the postcard meets or exceeds the given rate.

How Many Postcard Stamps to Mail a Letter

The answer is:
If you want to send a standard-sized letter within the United States with postcard stamps, you will usually need to use more than one stamp to meet the postage requirements for a one-ounce letter.

Pay attention:
In June 2023, mailing a one-ounce letter will cost 60 cents. But most stamps on postcards have lower prices, like 36 cents.
To figure out how many postcard stamps you need, split the postage rate you want by the value of the stamps. You would divide 60 cents by 36 cents in this case. About 1.67 is the answer.
Since you can’t use a part of a stamp, you must round up to the nearest whole number.

So, you must use two postcard stamps to meet or review the mailing requirements for a 1 oz letter.
This is how you determine how many domestic stamps you need for a postcard.
So, how many postcard stamps do you need to send a letter to another country?

As of June 2023, it will cost $1.45 to mail a foreign postcard. We still do the math based on the 36-cent value of the letter stamp, so we need 1.45/0.36 = 4.03.

So, you would need five postcard stamps to meet or go over the postage standards for a 1 oz international letter.
You already know how many postcard stamps you need to send your letter.
Wait a minute before you rush to the post office to mail a letter to a loved one or friend.
