You can contact the DWP’s PIP enquiry line to ask about your claim’s progress on 0800 121 4433, Monday to Friday, 9am to 5pm; Textphone users can call 0800 121 4493. Have your National Insurance number ready, as the DWP will need to confirm your identity. Some claimants may be able to view updates through an online service if the DWP has invited them to use it, but this is not available for every claim. Check the latest contact details and guidance on the official GOV.UK PIP page.
