Implementation Date: April 3, 2009
The e-IWO system (PDF) is being modified to send a monthly file of active Federal Employer Identification Numbers (FEINs) that can be processed through the OCSE e-IWO Portal.
The e-IWO system will send an FEIN file to states on a monthly basis. There is no impact to states. States can chose to electronically receive the active list of FEINs, or they can go to the e-IWO Workplace and review the list of active FEINs in order to maintain their list manually.
