An NHS number is a 10-digit number, like 485 777 3456.
Your NHS number is unique to you. It helps healthcare staff and service providers identify you correctly and match your details to your health records.
If you have an NHS number, it does not mean you’re automatically entitled to the free use of all NHS services.
In England, you usually have to pay patient contributions towards some NHS services.
Information: You do not need your NHS number to use NHS services, including booking appointments.
