How many stamps to mail a 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.

In the United States, the United States Postal Service (USPS) uses a weight-based pricing system for mail. The cost of postage is determined by the weight of the mailpiece, with heavier mailpieces requiring more postage.

Here are the current USPS rates for mailing a yellow envelope:

• A standard yellow envelope weighing up to 1 ounce (0.5 oz) requires 1 first-class mail stamp, which costs $0.55.
• A yellow envelope weighing 1-2 ounces requires 2 first-class mail stamps, which costs $1.10.
• A yellow envelope weighing 2-3 ounces requires 3 first-class mail stamps, which costs $1.65.
• A yellow envelope weighing 3-4 ounces requires 4 first-class mail stamps, which costs $2.20.
• A yellow envelope weighing 4-5 ounces requires 5 first-class mail stamps, which costs $2.75.

If you're mailing a yellow envelope internationally, the cost of postage will depend on the destination and the weight of the envelope. You can use the USPS's online postage calculator to determine the cost of postage for your specific mailpiece.

It's also worth noting that if you're mailing a yellow envelope with a large or irregular shape, you may need to use a larger envelope or a different type of mail service, such as Priority Mail. In this case, the cost of postage will be higher than for a standard yellow envelope.
