Hi Ana. I phoned Oxford Job Center on Nov 15, 4pm and they booked my appointment the next day at 12:30pm to apply for my national insurance number (NINO). I brought my passport, BRP, marriage certificate, proof of residence, and birth certificate as evidence. The interview took 5 minutes only.
The questions being raised were (1) birth date - verified against your birth certificate, (2) name - verified against your passport or BRP, (3) address - verified against your proof of residence, (4) husband's details: name, birthday, national insurance number, (5) why you need a NINO, (6) qualification/degree/job title.
If you wish to use your husband's last name no worries they will consider that. It will be written on the "Other Name" section of the application form. It will be verified on your marriage certificate. By the way, the Officer is the one to fill-up your form. After the interview the Officer gave me the LMS Reference Number, Form Number and contact details incase i have not received my NINO in 6 weeks. Likewise, if i wish to change my passport using my husband last name and i would like to update my name in my NINO, Tax Office shall be contacted and not the Job Center.
I got my NINO after 8 working days.
Chillax, questions are easy. Good luck on your application.
