Problems logging in?

To log in you will need your NS&I number, surname and password.

What is an NS&I number and where can I find it?

It's the unique identification number we sent you when you registered for our online and phone service (note that if you’ve opened an account online or by phone, you are automatically registered). You’ll need your NS&I number and password whenever you log in or call us. You’ll find it on any letter you’ve had from us since you’ve registered.

Your NS&I number is 11 digits long and starts with an 11, 21, 31 or 41.

Forgotten your NS&I number or the answers to your security questions?

You’ll need to download and complete a ’Forgotten security details’ form. Send it to us and we will post a temporary password to the address we hold on record. You'll then need to log in and re-enter your security details.
