What color envelopes can you mail

In the United States, the United States Postal Service (USPS) allows you to mail letters and flats in a variety of envelope colors, as long as they meet certain requirements. Here are some guidelines:

Standard Envelope Colors:

  1. White: This is the most common and accepted color for standard envelopes.
  2. Light Gray: USPS allows light gray envelopes, but they must be a specific shade that is not too dark or too light.
  3. Beige: Beige envelopes are also acceptable, but they must be a light, neutral color.

Allowed Non-Standard Envelope Colors:

  1. Pastel colors: Soft, pale colors like pale pink, baby blue, or mint green are allowed.
  2. Earth tones: Colors like brown, tan, or sienna are acceptable.
  3. Metallic colors: Envelopes with metallic finishes like gold, silver, or copper are allowed, but they must be matte or have a subtle sheen.

Colors Not Allowed:

  1. Bright or neon colors: Envelopes with bright, neon, or fluorescent colors are not allowed.
  2. Dark or bold colors: Colors like black, navy blue, or dark green are not allowed, as they may not be easily readable.
  3. Iridescent or holographic colors: Envelopes with iridescent or holographic finishes are not allowed.

Additional Requirements:

  1. Envelopes must be made of a durable material that can withstand mailing.
  2. Envelopes must have a minimum thickness of 0.007 inches (0.18 mm).
  3. Envelopes must have a clear, legible address and postage.

Remember to always check with your local post office or USPS website for any specific guidelines or restrictions on envelope colors in your area.
