How much is the regular mail stamp

The cost of a regular mail stamp, also known as a First-Class Mail stamp, varies depending on the weight and size of the mailpiece. As of 2023, the current rates for First-Class Mail stamps in the United States are:

Note that these rates apply to mailpieces that are not oversized, irregularly shaped, or contain hazardous materials. If your mailpiece falls into one of these categories, you may need to use a different type of postage or pay a higher rate.

It's also worth noting that the USPS offers a variety of discounts and promotions that can help reduce the cost of mailing. For example, you can get a discount on postage if you use a Forever stamp, which is a stamp that can be used to mail a 1-ounce letter at the current First-Class Mail rate, regardless of future rate increases.
