What is an interview for?

At the interview, we will ask you questions about who you are and why you want an NI number. This information, and any official documents you bring with you, will help to prove your identity and, where applicable, your right to work. You may also have to fill in a form to apply for an NI number.
When we give you the date of your interview, we will tell you what information or evidence to bring with you. The information or evidence you need to bring depends on why you need the NI number. The list below might give you an idea of the relevant documents.
The interview will usually be with one other person unless, for example, you need an interpreter. Sometimes we may ask for your permission to let us keep your documents for a short time. We will give you a receipt for any documents you let us keep.
