Yes, the official letter that you receive from JobCentre Plus bearing your National Insurance Number is accepted by overseas authorities as proof of National Insurance.

The original letter from the Department of Work and Pension does not contain a stamp or signature recognised by the FCDO, so both the original and a photocopy must be certified before legalisation.

A solicitor certifies that the original NI letter has been seen.

Notarising a copy of your National Insurance Number letter can be done in two ways:

1. The notary can notarise the NI letter as a “true copy.”
2. The notary can notarise that the NI letter is “on original.”

A ‘true copy’ confirm that the notary has seen the original – and confirming the NI letter as ‘an original’ requires the notary to take extra steps to verify the National Insurance Number.

For example, the notary could check with the Department for Work and Pensions (DWP) In England, Scotland, and Wales or the Department for Social Development in Northern Ireland [2].

Certification by a solicitor is sufficient for countries that are party to the Hague Convention 1961.

Countries that are not members of the Hague Convention may require notarisation.

Yes, anyone that has been issued a National Insurance number in the UK can have their NI letter apostilled.

All documents that have been issued in the UK can receive an apostille certificate. The NINo letter is a UK-issued document. Therefore, a certified copy of your National Insurance Number letter can be apostilled.

Any EHIC that was issued in the UK prior to 1 January 2021 can be apostilled. An EHIC issued in another EU country cannot be apostilled by the UK Legalisation Office of the FCDO.

In the UK, after 1 January 2021, the EHIC was replaced by a Global Health Insurance Card (GHIC). The UK’s GHIC can be apostilled by the FCDO.

Yes, you can get an apostille for other UK documents, such as P60, tax returns, pension documents, UK ID cards, etc.
