Common Questions and Answers

Here are some frequently asked questions about postage costs and stamps:

Is it the number of stamps or the total value that matters?

It’s not just the number of stamps; it’s the total value of the stamps that matters. For example, the first ounce of mail costs 60 cents, and each additional ounce (or part of an ounce) costs 24 cents. This total value determines the postage cost.

What if I need fewer stamps than the cost?

It’s important to have enough stamps to cover the total postage cost. While a combination of lower value stamps might be acceptable, mixing stamps from different years or with different denominations can cause issues. Using the appropriate total value in stamps ensures your mail is properly labeled and delivered.

Other Considerations: Additional Services

If you need additional services such as a return receipt or proof of delivery, these may incur additional costs. The current price for a First-Class Mail Forever letter stamp is 55 cents, which covers the first ounce. Each additional ounce costs 15 cents. The maximum weight for letters is 3.5 ounces.
