I think there is an issue with my U1 document

Hello, I've moved out of the UK almost two months ago and as soon as I did I applied for the U1 document. I've received this document today in my house in Spain but I think is incomplete. It doesn't include all the contributions I've made to the National Insurance and, also, in the "income details" section I can only see those wages I received from the last job I had in the UK but not for the previous ones. How can I solve this? Can I apply for another document with all my National Insurance Contributions of my time in the UK? Thanks a lot!

Hi Nicolas,
Thank you for your enquiry.
You will need to contact the National Insurance helpline and ask them to check the information on your U1 certificate.
The contact number is +44 191 203 70 10, lines are open from 8am to 6pm Monday to Friday.
Alternatively, you can complete another CA3916 and attach a covering letter explaining why you think the certificate that has been issued to you is incorrect.
Thank you.
