C5.4 National Insurance Number (NIN)¶
How to apply for a UK National Insurance Number (NIN)?
If you intend to work in the UK—whether part-time, an internship, full-time, or as a volunteer—you must apply for a National Insurance Number within 6 weeks. The full English name is National Insurance Number, abbreviated as NIN or NI. It is part of the UK's welfare system, used for tax purposes. These taxes fund benefits for non-working individuals, retirees, maternity allowances, unemployment support, and more.
If you are a British citizen, the UK government will automatically send you a NIN by post once you turn 16. If you are a non-British citizen, you need to apply. Student visas and dependent visas are eligible for application (though not all dependent visa applications are successful, depending on individual circumstances). Short-term visas and applicants under 19 are generally ineligible. Those who already have a NIN printed on their BRP cannot reapply.
How to apply:
Prepare your BRP, passport, digital photo, and other required documents in advance.
Visit the official application link [https://www.gov.uk/apply-national-insurance-number], click the application button, and fill in the information step by step. Note: The webpage does not save data and you cannot stay on a single page for too long, as this may cause the page to freeze or refresh, requiring you to restart. Fill in the details carefully and double-check before submission.
After completing and submitting the application, you will receive an email containing your reference number. The email will inform you if additional identity verification is needed. Once your identity is verified, you will receive your NIN in approximately 8 weeks.
Reminder: If you have not received your NIN after 8 weeks, contact the official authorities. Before contacting, prepare your passport, BRP, and the reference number from the confirmation email.
