Postal tracking is a service provided by postal and courier companies that allows customers to monitor the status and location of their mail or packages. By using a unique tracking number, customers can see where their item is in the delivery process, from the moment it is shipped until it reaches its final destination. This service enhances transparency and provides peace of mind, as customers can receive updates on their shipment's progress. Many companies offer online tracking tools or mobile apps, making it easy to check the status of a package anytime and anywhere.
