If you would like some information regarding National Insurance then contact HMRC on their UK phone number 0300 200 3500. You can also contact them via textphone on 0300 200 3519 or if you’re abroad you can dial their international helpline +44 191 203 7010.
National Insurance is very important for any UK Resident because it is by virtue of their regular contributions that eligibility for certain government benefits like the state pension will be determined.
If you’re a UK resident older than 15 years old, earning upwards of £155 each week from your job or you are a self-employed citizen earning at least £5,965 each year, then you need to make contributions to the National Insurance fund. Before you’re able to do this, you first need to secure your National Insurance number which is given to you on your 15th birthday or once you become a British citizen.

To apply for a National Insurance number you need to call HMRC on their telephone contact number 0345 600 0643. Alternatively if you require Textphone or minicom services then you can dial 0345 600 0644.
