Tracking Number & Area Code

Do you know that some carriers require users to input both tracking number and area code (or postalcode) for tracking a shipment? We believe this is to avoid duplicate records in their tracking system and also strengthen the privacy protection of the tracking number. When you track such shipment in AfterShip, you can enter the tracking number followed by ":" and area code (XXXXXXXXXXXXX:YYYY). Read more for more examples.
