In response to some National Insurance number Verification Requests (NVRs) and Full Payment Submissions (FPS) with missing or incorrect National Insurance numbers, HM Revenue & Customs has issued a number of National Insurance numbers without the final letter (A, B, C or D) of the number.

The issue of National Insurance numbers is currently on hold whilst we investigate this.

We have identified three scenarios and what actions employers should take.

Scenario 1 - the incorrect National Insurance number was included on an FPS and the correct number goes back with no suffix

You should use the National Insurance number that was sent back and use the suffix that was on the original submission - A, B, C or D. If you do not know what this was, you should enter the space bar. Please do not guess which letter (A, B, C or D) should be used.

Scenario 2 - no National Insurance number was provided on the FPS and the correct number goes back with no suffix

You should use the National Insurance number that was sent back, but enter the space bar instead of the suffix. It is important to enter the space bar, rather than trying to truncate the number to eight characters. Please do not guess which letter (A, B, C or D) should be used.

Scenario 3 - employer sends NVR and the National Insurance number supplied by HMRC is without a suffix

You should use the National Insurance number that was sent back but enter the space bar instead of the suffix. Use the space bar rather than trying to truncate the number to eight characters. Please do not guess which letter (A, B, C or D) should be used.

Please note that using a National Insurance number without a suffix (A, B, C or D) should be the exception, in these scenarios only.

We apologise for any inconvenience whilst we investigate this issue.
