3.24.212.2.3 (05-07-2021) Name Control/Check Digit Enter Name Control (NC) as follows: Press <Enter> for the Check Digit field. The system positions the cursor on the Name Control field. Enter the four-character Name Control from the First Name Line area in the Name Control field (see IRM 3.24.37, ISRP System, General Instructions, or IRM 3.24.38, ISRP System, BMF General Instructions, for Name Control determination).

Name Control Check Against Enhanced-Entity Index File
3.24.212.2.4 (01-01-2021) Name Control Check Against Enhanced-Entity Index File The system accesses the Enhanced-Entity Index File (E-EIF) to determine if the account is already established on the Master File. This is done to reduce the number of unpostables. The system accesses E-EIF and prompts for verification. Enter Y for yes or N for no. When the check is completed, the next prompt appears and entry may continue. If the account is located, the Check Digit appears in the Check Digit field on the screen, if available. The TIN/Check Digit/Name Control fields bypass verification. If the account is not located, the Name Control remains on the screen as entered. This procedure affects all forms except those with a Tax Class of "077" or "977" .
