How many stamps to mail yellow envelope

The number of stamps needed to mail a yellow envelope depends on the weight and size of the envelope, as well as the destination and type of mail service used.

Here are some general guidelines:

• For a standard yellow envelope weighing up to 1 ounce, you'll need:
  • 1 first-class stamp (currently $0.55) for domestic mail (within the United States)
  • 1 international first-class stamp (currently $1.20) for international mail
• For a yellow envelope weighing over 1 ounce, you'll need:
  • Additional ounces of postage, which are currently $0.15 per ounce for domestic mail and $0.20 per ounce for international mail
• For larger or heavier yellow envelopes, you may need to use a larger envelope or a package service, such as Priority Mail, which has its own rates and requirements.

It's always a good idea to check the current postage rates and regulations on the United States Postal Service (USPS) website or at your local post office to ensure you have the correct postage for your yellow envelope.
