What is the required format for the Employer (Office Number / PAYE Reference Number)?
The HMRC Office Number is the first part of the Employer’s PAYE reference and is three digits. This number can be obtained on a P6/P9 coding notice, or an Annual/Budget pack letter.
For example, if the Employer’s PAYE reference is 123/A246, the HMRC Office Number is 123.
The first part of the reference is the three-digit HMRC Office Number and the second part of it after the forward slash is the employer reference.
For example, 123/A246
