TIN number UK.

[musical box]

"For most individuals in the UK the TIN will be their National Insurance Number".
Is this statement correct?

( "A Taxpayer Identification Number (TIN) is an identification number used by the Internal Revenue Service " )

Yes: https://www.oecd.org/tax/automatic-exch ... UK-TIN.pdf

That link also mentions a UTR number but I don't recall ever having or needing to provide that, so that might be more for people who are/were self-employed, the NI Number was the only thing I ever saw on payslips/tax assessments etc.
