We have reviewed the titles of myIR letters and have made changes to improve clarity. The changes will be in stages from 12 February to early April 2025.

You can expect to see these changes.

  • New titles for around 80% of our letters.
  • Updates to style and format.
  • An updated mail type code reference list on our website.

Mail type code reference list

Please note, if you receive an email alert for a letter and are delayed logging in to view the letter, its title may not match the email alert. Your alert will still take you to the current version of the letter in myIR, even if the title is different.
