Can you mail big yellow envelopes

The infamous "big yellow envelopes"!

In the United States, the United States Postal Service (USPS) has specific guidelines for mailing large envelopes, also known as "flat rate envelopes" or "large envelopes." Here are the details:

Size: The USPS defines a large envelope as one that measures at least 6.125 inches (15.55 cm) in height, 11.5 inches (29.21 cm) in length, and 0.007 inches (0.0178 cm) in thickness.

Weight: Large envelopes can weigh up to 13 ounces (368 grams).

Mailing options: You can mail large envelopes using the following services:

  1. Flat Rate Envelope: USPS offers a flat rate envelope service, which allows you to mail a large envelope for a fixed price, regardless of its weight. The cost is $7.95 for domestic mail and $24.95 for international mail.
  2. Priority Mail: You can also use Priority Mail to mail large envelopes. The cost will depend on the weight and destination of the envelope.
  3. First-Class Mail: If the envelope weighs less than 13 ounces, you can use First-Class Mail, which is a more affordable option.

Tips:

Remember to check the USPS website or consult with a postal worker if you have any questions or concerns about mailing large envelopes.
