Why do some deduction from earnings orders have National Insurance numbers instead of reference numbers?
Deduction from earnings orders that are issued with a National Insurance number are for cases that have been assessed under the new rules since 3rd March 2003. Until all the existing cases are transferred over to the new scheme, we will be operating two different schemes. Cases assessed under the old rules will continue to quote reference numbers on the orders. As an employer you may therefore receive deduction from earnings orders with either reference numbers or national insurance numbers.
