You can use the official GOV.UK State Pension service to check your State Pension forecast, National Insurance record and payment details. If you cannot sign in, check your Government Gateway user ID and password, then use the recovery options or contact the relevant HMRC or Department for Work and Pensions helpline shown on GOV.UK. The service may ask for identity checks, and the information displayed can depend on your personal circumstances and contribution record. Avoid sharing your login details with anyone, and contact GOV.UK directly if you suspect an account or identity problem.
