Indeed - people sometimes think that the National Insurance number is our identifier - but the forget you can use many names with that, and people get by just fine.

My mother is an actress and holds bank accounts (and gets paid) in her full name, her acting name and in her maiden name - I don't think the NI knows about these names any more than they know that she's paying tax to that NI number. Employers don't care as long as you provide an NI - there is not check to make sure it is the 'right name'.

They write to her at her 'full name' but she's able to live (entirely legally) as her other names too.
