It is now a mandatory requirement for Level 1 users of the SMS to add their National Insurance number into the system. The update will be reflected on the SMS immediately once the information has been entered and saved.

This requirement applies to new Level 1 users, as well as existing Level 1 users, so existing users will need to log into the SMS to add this information. It is expected that the requirement will soon be extended to Authorising Officers and Key Contacts as well.
