Can you mail yellow envelopes

In the United States, the United States Postal Service (USPS) allows mailing of yellow envelopes, but there are some restrictions and considerations to keep in mind:

1. Color restrictions: While yellow envelopes are technically allowed, the USPS has specific guidelines for envelope colors. According to their regulations, envelopes can be any color except for:
   • Red, which is reserved for priority mail and express mail services.
   • Green, which is used for certain types of mail, such as certified mail and return receipt mail.
   • Blue, which is used for certain types of mail, such as priority mail and express mail services.
2. Special handling: Yellow envelopes may require special handling or additional postage, depending on the type of mail being sent. For example:
   • If you're sending a yellow envelope with a First-Class Mail stamp, it may be subject to additional postage or special handling fees.
   • If you're sending a yellow envelope with a Priority Mail or Express Mail stamp, it may be subject to specific handling procedures and fees.
3. Business reply mail: If you're using yellow envelopes for business reply mail (BRM), you'll need to follow specific guidelines and regulations set by the USPS. BRM envelopes must be clearly marked with the business reply mail indicia and must meet specific size and weight requirements.
4. Customs forms: If you're sending yellow envelopes internationally, you may need to attach customs forms, such as a PS Form 2976, to the envelope. This form provides information about the contents and value of the mail.

In summary, while yellow envelopes are allowed for mailing, it's essential to follow USPS guidelines and regulations to ensure proper handling and delivery. If you're unsure about specific requirements or restrictions, it's always best to consult with your local post office or the USPS website.
