Can i use an international stamp on domestic mail

In general, it is not recommended to use international postage stamps on domestic mail in the United States. Here's why:

1. Incorrect postage: International postage rates are typically higher than domestic rates, so using an international stamp on domestic mail could result in overpayment. You may be able to get a refund, but it's still inconvenient.
2. Inadequate postage: Domestic mail requires a specific postage rate, which is usually lower than the international rate. Using an international stamp might not provide enough postage to cover the cost of delivery.
3. Potential delays: If the postal service discovers that you've used an international stamp on domestic mail, they may delay or return the item to you.

However, there are some exceptions and considerations:

1. International Forever Stamps: The United States Postal Service (USPS) offers International Forever Stamps, which can be used on domestic mail to destinations outside the United States. These stamps are specifically designed for international mail and have the correct postage rates.
2. Global Forever Stamps: The USPS also offers Global Forever Stamps, which can be used on domestic mail to destinations outside the United States, including APO/FPO addresses. These stamps have a fixed rate that covers the cost of postage to most international destinations.
3. Special circumstances: In some cases, you might be able to use an international stamp on domestic mail if you're sending a package or letter to a specific destination that requires a higher postage rate. For example, if you're sending a package to a remote area or a military base, you might need to use an international stamp to ensure it's properly delivered.

To avoid any issues, it's always best to use domestic postage stamps or purchase a domestic postage rate from the USPS for your domestic mail. If you're unsure about the correct postage rate or have specific questions, you can consult with a postal worker or visit the USPS website.
