Hi, Thanks for the reply, as I said I have already contacted the Technical support with HMRC online services but they replied it is not technical problem and cannot help me. I have also called the childcare service but they said I need to create the government gateway in order to get the code. So, it goes back to my question how to pass my identification check in the government gateway? Appreciate if I can have the postal address to contact HMRC officer for the identification check please? Thank you.

Hi there, I am currently trying to submit my application for natiralisation as my BRP expires 31Dec2024.. I can log-in to Government Gateway with no problem, however when I enter my number, date of birth and NI number I keep getting a "we cannot confirm your identity" message. I have filled in 95% of my application last November 2023 and now need to get in to pay and submit application. I don't know where to go from here, can anyone please give me advice on who can help me? Thanks!
