You will find the USPS parcel tracking number on the receipt or shipping label you receive when sending your package. It is often printed near the barcode or beneath the sender and recipient information. You can use this USPS tracking number on our tracking service to see the current status and location of your parcel. USPS tracking numbers come in several formats depending on the service type. Domestic services such as USPS Tracking, First-Class, and Priority Mail usually have 20 to 22 digits, all numeric. International services like Priority Mail International and Express Mail International often start with two letters, followed by nine digits, and end with “US” (for example, EC123456789US). Other specialized services like Registered Mail may use similar alphanumeric formats. If your tracking number is between 20–22 digits or follows the letter-number-letter pattern, it is valid and trackable.
