NIM39205 - National Insurance Numbers (NINOs): Confirming a NINO: Confirmation by individual - Form CA5403

If someone cannot remember their NINO, they may find it on pay or benefit documents for example a P60.

If a customer still needs to confirm their NINO, or request a replacement card should either:

• contact HMRC Call Centre (CRCC) on 0845 915 7006, or
• go to their local Jobcentre plus Office (DSD in Northern Ireland).

HMRC Action

CRCC will determine the NINO where possible and issue CA5410, confirmation of NINO, to the customer.

Forms CA5410 are used for customers who have:

• forgotten their NINO and want to be reminded of it (CA5410), or
• a NINO and want to apply for a replacement card (CA5410C).

If the NINO cannot be found, or the customer cannot be helped on the telephone, they will be referred to HMCR NICO, Additional Business Workstream or Jobcentre plus to confirm identity and update personal details.

DWP Action

If the customer goes to a JobCentre Plus or social security office, staff will confirm the customer's identity and try to trace the NINO. If the NINO is confirmed, they will give it to the customer. If not, they should arrange for an evidence of identity interview to allocate a NINO.

If a customer has never had a NINO, see NIM39215.
