You can get this online or over the phone. To apply online go to http://www.gov.uk/check-state-pension and follow the instructions from there. You’ll need to verify your identity as part of the process, either through your Government Gateway account if you have one, or by using the GOV.UK verify service, so you will find it helpful to have one or more of the following to hand: A valid UK passport. Bank Statement showing direct debit payments. A P60 for the latest tax year. Payslips – for the last 2-3 months. National Insurance Number. You may also need your mobile phone to receive a security code. To apply by phone, call 0345 3000 168. You’ll have to do this if you are within 30 days of your State Pension age, or already over this age.
