What is mail number

A "mail number" is a unique identifier assigned to a piece of mail, such as a letter, package, or parcel, by a postal service or courier company. It is used to track the movement and status of the mail item as it is processed and delivered.

Mail numbers are typically alphanumeric codes that consist of a combination of letters and numbers. They may be printed on the outside of the mail item, such as on a label or envelope, or they may be assigned electronically and stored in a database.

Mail numbers serve several purposes:

  1. Tracking: Mail numbers allow postal services and courier companies to track the movement of mail items as they are processed and delivered. This helps to ensure that mail items are delivered to the correct address and that any issues or delays can be quickly identified and resolved.
  2. Identification: Mail numbers help to identify specific mail items and distinguish them from other mail items. This is particularly important for packages and parcels, which may be sent to multiple recipients or have multiple items inside.
  3. Routing: Mail numbers are used to route mail items to the correct destination. Postal services and courier companies use mail numbers to sort and prioritize mail items, ensuring that they are delivered efficiently and effectively.
  4. Customer service: Mail numbers provide a convenient way for customers to track the status of their mail items and contact the postal service or courier company if there are any issues.
