Can you send a yellow envelopes in the mail

In the United States, the United States Postal Service (USPS) has specific guidelines for the colors of envelopes that can be used for mailing. According to the USPS, the only colors that are officially approved for use on envelopes are:

  1. White
  2. Light blue
  3. Light gray
  4. Brown
  5. Kraft (a type of brown paper)

Yellow is not one of the approved colors for envelopes. However, you can still use yellow envelopes for mailing, but you'll need to make sure they meet certain requirements:

  1. The envelope must be made of a material that is approved by the USPS, such as paper or cardboard.
  2. The envelope must be at least 3.5 inches high and 6.125 inches long.
  3. The envelope must have a minimum of 1/4 inch of clearance around the edges to ensure that the contents don't get damaged during processing.
  4. The envelope must have a return address and the recipient's address printed in the correct format.

It's also important to note that using a yellow envelope may affect the visibility of the address and the overall appearance of the mailpiece. If you're planning to send a yellow envelope, make sure the address is printed in a clear, legible font and is easy to read.

In summary, while yellow envelopes are not officially approved by the USPS, you can still use them for mailing as long as they meet the required specifications and guidelines.
