Question: 
Track and Trace isn't accepting my reference number
Answer (teaser): 

Details of how to check whether it’s a valid reference number.

Check that you have a valid reference number 

A Track & Trace reference number is:

  • 13 digits long
  • starts with two letters (e.g. AA) followed by nine numbers
  • ends with the two letters ‘GB’

For example, a reference number could look like this: AA123456789GB.

How to find your reference number 

You can find your reference number on your tracking label.

If your reference number doesn’t end in GB, it will have been posted from another country.
