NIM39210 - National Insurance Numbers (NINOs): Confirming a NINO: Confirmation by employer - Form CA6855
Regulations 66 and 104 of the Social Security (Contributions) Regulations 2001
All employees must give their NINO to their Employer to enter on
their payroll records.
If the employee can’t remember or find their NI number,
the employer may be able to find it on a document such as a form
P45 or form CA4139 (CF383) certificates of election. If not, they
need to keep a record of the employee's details until the NINO is
received, including:
- full name
- address,
- date of birth, and
- gender.
The employer may have to send a form P46 to their local HMRC
office about the employee, in which case the employee's NINO will
be traced automatically and there is no need to use another form.
If necessary, HMRC NICO will carry out a clerical trace. If the
NINO is traced, HMRC NICO will notify the employer on form P46-5,
and notify the employee on form P217.
If the employer does not have to send form P46 to their local
HMRC office, they can use the National Insurance number tracing
service by using form CA6855, which is available from:
- the Employer’s Orderline on 0845 7 646 646
- any HMRC office
- www.hmrc.gov.uk/employers, 'I want to trace a National Insurance number'
- the Employer's CD-ROM
The employer may use their own schedule with the information set out in the following order:
- employee’s title
- surname
- first name(s)
- address
- date of birth
- gender
- works/payroll number
- date employment started
- date employment ended (if applicable)
- employer’s PAYE reference.
Form CA6855 or schedule should be sent to:
HMRC
National Insurance Contributions Office
Evening Work Centre
Room BP3101
Benton Park View
Newcastle Upon Tyne
NE98 1ZZ
If HMRC NICO trace the employee’s NINO, they will
notify the employer on form CA6856. If they cannot trace a NINO,
they will tell the employer to ask the employee to apply for a
NINO. See
