Administrative Numbers
Reference numbers similar in format to NI numbers are sometimes allocated for tax or benefit purposes with special prefix letters. Special prefixes used in the past include the letters OO (for tax credit claims), CR (for investigations), FY (formerly for Attendance Allowance claims, named after the Fylde social security office where claims were processed), MW (used from 1980 to 1987 for migrant workers), NC (formerly for stakeholder pensions), PP (for use by pension schemes as PP999999P), and PY or PZ (both used for tax-only accounts created prior to 2003).

Famous quotes containing the word numbers:
“The barriers of conventionality have been raised so high, and so strangely cemented by long existence, that the only hope of overthrowing them exists in the union of numbers linked together by common opinion and effort ... the united watchword of thousands would strike at the foundation of the false system and annihilate it.”
