National Insurance number
The National Insurance number is used as a reference number in the Pay As You Earn system, and also by the self-employed. It is also used in applications for Individual Savings Accounts (ISAs), to check that an individual has opened only one ISA in a tax year.
Social security in France
The "Allocation de Solidarité aux Personnes Agées" (solidarity allowance for the elderly) (ASPA) is a French state pension for elderly people, whether former employees or not, on low incomes. It replaced the multiple components of the minimum pension ("Minimum Vieillesse") from 1 January 2006.
To qualify for ASPA, the recipient must live in France or French territory, and meet age and financial need criteria.
