How many stamps to mail out of state

The number of stamps needed to mail a letter or package to another state in the United States depends on the weight and size of the item, as well as the destination zip code. Here are some general guidelines:

Letters:

• A standard letter (1 oz or less) to another state typically requires 1 First-Class Mail stamp, which costs $0.55 as of 2022.
• If the letter weighs more than 1 oz, you'll need additional ounces of postage. Each additional ounce costs $0.15, so a 2-oz letter would require 2 stamps, and so on.

Packages:

• For packages weighing up to 13 oz, you'll need 1 First-Class Package Service stamp, which costs $3.50 as of 2022.
• For packages weighing 14 oz or more, you'll need additional ounces of postage. Each additional ounce costs $0.15, so a 14-oz package would require 2 stamps, and so on.
• For packages weighing more than 70 lbs, you'll need to use a commercial rate or a USPS Retail Ground service.

Other factors to consider:

• If you're mailing a package to a PO box, you may need to use a different type of postage or add an extra fee.
• If you're mailing a package to a military address, you may need to use a different type of postage or add an extra fee.
• If you're mailing a package to a foreign country, you'll need to use international postage rates, which vary depending on the destination and weight of the package.

How to calculate postage:

You can use the USPS Postage Calculator tool on the USPS website to determine the exact postage needed for your item. Simply enter the weight, size, and destination zip code, and the calculator will provide the required postage amount.

Alternatively, you can visit your local post office and ask a postal worker to help you calculate the postage. They can also provide you with the necessary stamps or postage labels.
