How to Apply for a National Insurance Number for a Looked-After Child: A Complete Guide

A National Insurance (NI) number is essential for young people as they transition into adulthood, enabling them to work and access the benefits system. However, children in the care of local authorities do not automatically receive an NI number. Social workers must take specific steps to apply on their behalf. Here’s a concise guide to managing this process.

Who Can Apply?

Children under local authority care require their social worker to apply for a National Insurance number. Each child needs a separate application, which must be submitted directly to HMRC by the social worker.

How to Apply

To apply for a National Insurance number for a looked-after child, follow these steps:

1. Timing: Applications can only be submitted once the child reaches the age of 15 years and 9 months.
2. Official Letter: Write a letter on the local authority’s official letterhead, including the following details:
   • A statement confirming you are a social worker applying for an NI number for a looked-after child.
   • The child’s full name, any previous names, and date of birth.
   • The date the child entered care and their current residential address.
3. Additional Information (if available):
   • Previous addresses (e.g., the parents’ or last known address before entering care).
   • A photocopy of supporting documents, such as:
     • The child’s birth certificate.
     • Care order documentation.
     • The ID page of the child’s passport.
     • Home Office documents or residence permit (for unaccompanied minors supported by the Home Office).
4. Send the Application: Post the completed application, along with photocopies of supporting documents, to:
   PT Operations North East England
   HM Revenue and Customs
   BX9 1AN

Important: Do not send original documents, as HMRC does not return them.

What Happens Next?

• HMRC typically sends a confirmation letter with the child’s National Insurance number within seven weeks.
• If further information is required, HMRC will contact the social worker directly using the details provided in the application.

Need Updates or Help?

For updates on an application, social workers can contact the HMRC Juvenile Team at 03000 555 716 during business hours. Avoid emailing HMRC, as emails are not accepted for these applications.

Conclusion

Applying for a National Insurance number for a looked-after child is a straightforward but essential process. By ensuring the application is complete and accurate, social workers can help these young individuals access critical opportunities as they prepare for adulthood.

Stay proactive, follow the required steps, and reach out to HMRC if you need support with the process.
