Royal Mail uses a unique identifier system to track and manage mail items. Here are the different types of IDs used by Royal Mail:

1. Postcode: A 7-character code that identifies a specific geographic area. It's used to sort and deliver mail.
2. Postcode Sector: A 6-character code that identifies a smaller geographic area within a postcode. It's used to further sort and deliver mail.
3. Postcode Unit: A 5-character code that identifies a specific address within a postcode sector. It's used to deliver mail to a specific address.
4. Item Identification Number (IIN): A unique 13-digit number assigned to each mail item. It's used to track and manage mail items throughout the delivery process.
5. Tracking Number: A unique 13-digit number assigned to each tracked mail item. It's used to track the item's progress and provide updates to the sender and recipient.

These IDs are used in various ways, such as:

• Sorting and delivering mail
