IDM Registration Information

Before asking for access, get instructions from your organization or CMS contact. The instructions should include application specific information you need, such as:

  • Social Security Number (SSN) or Tax Identification Number (TIN)
  • Legal business name (LBN) or organization
  • Application name
  • Application role
  • Other information specific to your application such as contract number, Gentran mailbox, NPI, or organization number

Create a user id and password if you don’t already have a user id and password. IDM lets you create a user id up to 74 characters. But some applications restrict the number of characters and special characters in the user id. Check with your CMS point of contact.

Not every CMS application needs the same information, so make sure to get specifics from your organization or CMS contact.
