The United States Postal Service will ship mail and packages to destinations all over the world. When you ship internationally, there are varying delivery options, ensuring different delivery times. Of course, the quicker the delivery, the more expensive it is. Priority Mail International is one delivery option. It provides mail delivery to 190 countries, according to the USPS, and will deliver in six to 10 business days. Online tracking is available for Priority Mail International packages, but not for flat-rate envelopes or small flat-rate boxes.
Log on to the USPS website (see Resources).
Click the red "Track & Confirm" link at the top of the page.
Enter the label or receipt number for the package. According to USPS, the format of a Priority Mail International number is CP 000 000 000 US (as an example).
Click "Go." The next screen will show the delivery status of your package. Delivery information may be unavailable for certain destinations.
