International Mail
You can mail postcards, letters, large envelopes, and packages from the United States to other countries. As with domestic mail, you can choose the best service based on speed, cost, and extra services. Customs declaration forms are required on most international packages. All Customs forms must be electronically generated.  If you are not able to do this, take your hand-written Customs form to any post office and the retail clerk will be happy to submit the electronic information for you. To learn more about options for international mail and to calculate postage, visit or call 1·800·ASK·USPS. Your Post Office can also help you send mail internationally.
