Can i use three first class stamps for international mail

In the United States, the cost of international mail varies depending on the destination, weight, and size of the item. The United States Postal Service (USPS) uses a weight-based pricing system for international mail, which means that the cost of shipping increases as the weight of the item increases.

As of 2022, the USPS rates for international mail are as follows:

• Small flat rate envelope (up to 1 oz): $13.75
• Small flat rate envelope (over 1 oz): $16.75
• Medium flat rate box (up to 2 lbs): $24.75
• Large flat rate box (up to 2 lbs): $34.75
• Large flat rate box (over 2 lbs): $44.75

For international mail that weighs more than 1 oz but less than 1 lb, the cost is based on the weight of the item. For example:

• 1 oz to 2 oz: $2.75
• 2 oz to 3 oz: $3.25
• 3 oz to 4 oz: $3.75
• 4 oz to 5 oz: $4.25
• 5 oz to 6 oz: $4.75

For international mail that weighs more than 1 lb, the cost is based on the weight of the item in increments of 1 lb. For example:

• 1 lb to 2 lbs: $6.75
• 2 lbs to 3 lbs: $8.75
• 3 lbs to 4 lbs: $10.75
• 4 lbs to 5 lbs: $12.75
• 5 lbs to 6 lbs: $14.75

In general, it's not possible to use three first-class stamps for international mail, as the cost of international mail is typically higher than the cost of domestic mail. However, you can use a combination of stamps and a postage label to pay for international mail. For example, you could use a combination of first-class stamps and a global forever stamp to pay for international mail.

It's always a good idea to check the USPS website or consult with a postal worker to determine the correct postage for your international mail item.
