Initially, users must register online with e-Services and will create a User Name, Password and PIN that will allow them to access the system electronically. Once the on-line registration is completed, users receive, at their home address, a confirmation token that they must validate on-line within 28 days of the initial registration. All users within a firm must complete their own registration to have an eServices account established for their individual username and password. Once users are confirmed, the Principal, (person at your firm responsible for completing the TIN Matching application and assigning user roles), will complete the application and all confirmed users may begin using Interactive or Bulk TIN Matching that same day.
