User IDs must be between 5-100 characters and unique (cannot already be taken by another user).

Passwords must be a minimum of 12 characters and include a lowercase letter, uppercase letter, number (0-9), and symbol (!@#$%^&*). They cannot contain first name, last name, or part of user ID.

HARP is a secure identity management portal and asks for personal information to verify the user's identity. HARP uses Experian to remotely proof users by taking user-entered data, such as date of birth and social security number (SSN), to generate a list of personal questions for the user to answer to verify his/her identity.

• RIDP is the process of validating sufficient information that uniquely identifies you (e.g., credit history, personal demographic information, and other indicators). This method is used for verifying the identity of a user as opposed to manual proofing or in-person proofing. If you are requesting electronic access to protected CMS information or systems, you must be identity proofed to gain access.
• CMS uses the Experian identity verification system to remotely perform identity proofing. Experian is used by CMS to confirm your identity when you need to access a protected CMS Application.
• You may have already encountered RIDP through various interactions with banking systems, credit reporting agencies, and shipping companies.
• When you log in to HARP, you will have the option to RIDP. You will be asked to provide a set of core credentials which include:
  • Full Legal Name, Social Security Number, Date of Birth, Current Residential Address
• Experian will use your core credentials to locate your personal information in Experian and generate a set of questions. Experian will attempt to verify your identity to the appropriate level of assurance with the information you provided. Most users can complete the ID proofing process in less than five minutes. If you encounter problems with RIDP, you will be asked to contact Experian Support Services via telephone at (866) 578-5409 to resolve any issues.

If you cannot identity proof online, you will be asked to contact the Experian Verification Support Services Help Desk at (866) 578-5409. The system will provide you with a Reference Number to track your case. For security purposes, the Experian Help Desk cannot assist you if you do not have the reference number.
