Use /confirmIdNumber to validate that a partial ID Number, whether provided by the user or another source, matches the stored record. ID Number refers to the primary identification method utilized by your program. Common ID Numbers include:

• Social Security Number (SSN)
• Passport Number
• Driver's License Number

This endpoint allows you to securely validate whether a provided ID Number is valid without revealing or transmitting the full number. This is particularly useful in customer service scenarios for verifying a user's identity, which is why this functionality is also included in SST.

The number of digits required to verify will be variable per your program settings. To retrieve a full ID Number, use Retrieve ID Number
