Can you mail heavier envelopes with two stamps

In the United States, the United States Postal Service (USPS) has a weight-based pricing system for mail. The number of stamps required to mail a letter or envelope depends on its weight and size.

For a standard letter (up to 1 oz), one Forever Stamp is sufficient. However, if you need to mail a heavier envelope, you'll need to use additional postage.

Here's a general guideline:

For envelopes heavier than 5 oz, you'll need to use additional postage or a larger envelope that meets the USPS's weight and size requirements.

To determine the correct postage for your heavier envelope, you can:

  1. Weigh the envelope using a postal scale or a digital scale.
  2. Check the USPS website or consult a postal worker to determine the correct postage based on the envelope's weight and size.

In general, if you're mailing an envelope that weighs more than 1 oz, you'll need to use additional postage. Two Forever Stamps ($1.10) would be sufficient for an envelope weighing up to 2 oz, but you may need more stamps or a larger envelope for heavier mail.

Remember to always check the USPS website or consult a postal worker if you're unsure about the correct postage for your mail.
