Can i mail a brown envelope with stamps

In the United States, the answer is yes, you can mail a brown envelope with stamps. However, there are a few things to keep in mind:

1. Make sure the envelope is the correct size: The United States Postal Service (USPS) has specific size requirements for envelopes. A standard #10 envelope is 4 1/8 inches long, 9 1/2 inches wide, and 0.007 inch thick. If your brown envelope is larger or smaller than this, it may not be accepted by the USPS.
2. Use the correct postage: You'll need to affix the correct amount of postage to your envelope. You can use a postage scale or consult the USPS website to determine the cost of postage based on the weight and size of your envelope.
3. Use a valid stamp: You can use a Forever Stamp or a Global Forever Stamp on your brown envelope. These stamps are valid for one ounce of mail and can be used for domestic or international mail.
4. Make sure the envelope is properly addressed: Ensure that the recipient's address is correctly written and includes the correct zip code.

Some additional tips:

• If you're mailing a large or irregularly shaped envelope, you may need to use a special rate or a larger stamp.
• If you're mailing a package, you'll need to use a shipping label and pay a higher rate based on the weight and dimensions of the package.
• If you're unsure about the postage or mailing requirements, you can always consult with a postal worker or visit the USPS website for more information.

I hope that helps!
