Can i put 3 stamps on a priority mail envelope

According to the United States Postal Service (USPS), you can indeed use multiple stamps on a Priority Mail envelope, but there are some guidelines to keep in mind:

  1. Weight-based pricing: Priority Mail rates are based on the weight of the package, not the number of stamps used. So, even if you use multiple stamps, the rate will still be determined by the weight of the package.
  2. Stamp values: You can use a combination of stamps with different denominations to reach the total postage required for your Priority Mail package. However, each stamp must be valid for the current postage rate.
  3. Maximum postage: There is no limit to the number of stamps you can use on a Priority Mail envelope, but you must ensure that the total postage does not exceed the maximum allowed for the weight and size of your package.

Here's an example:

Let's say you have a Priority Mail envelope weighing 1 pound (16 oz) and you want to use stamps to pay for the postage. The current Priority Mail rate for a 1-pound package is $7.95.

You could use:

In this example, using 3 x $2.50 stamps would not be enough to cover the full postage, while using 2 x $3.50 stamps would leave a small shortage. Using a single $7.00 stamp would cover the exact amount.

Remember to always check the current postage rates and calculate the total postage required for your package before sending it. You can use the USPS website or consult with a postal clerk for assistance.
