Verification for Lenders

UC Davis has contracted with Equifax and securely transmits information to The Work Number at every payroll cycle to ensure that the employment and income data available to authorized verifiers is current. When an employee applies for credit or other services where proof of employment or income are required, the employee provides consent to the credit grantor to verify that information. This is normally in the form of a signed acknowledgement during the application process.

The credit grantor—who has been carefully screened by Equifax and previously credentialed to use the system—logs in, provides a valid reason or permissible purpose (as defined by the Fair Credit Reporting Act) for requesting the information, and instantly retrieves the data. 

In some instances, the verifier must obtain a Salary Key prior to verifying income. A Salary Key is a unique six-digit number that allows one-time access to an employee’s income data. The employee creates the Salary Key at www.theworknumber.com/employees and provides it to the verifier.

Data available to verifiers includes:

  • Employee name
  • Most recent hire date
  • Termination date (if no longer employed)
  • Total time with company
  • Job title
  • Rate of pay
  • Gross earnings for current year-to-date, including base pay, overtime, bonuses, and commissions
  • Gross earnings for last year and two years past, including base pay, overtime, bonuses, and commissions
