What is a Database?

A database is a central repository for information or data that allows access to one or more users. This information is typically organized into what are known as records.

What is a Record?

A record is a discrete set of information that is stored in a database. In the case of The Work Number database, each record describes a person's time with a specific employer. The Work Number database contains employment and income records from thousands of employers, and in many cases these records include information about a person's current and previous employers.

Do I need anything special to access an income verification?

Equifax requires that verifiers have employee authorization to access income information. This allows the employee control over who has the ability to pull their income.

What is a Salary Key?

A Salary Key is one form of employee authorization that gives a verifier the right to view a person's income information. There are some things you should keep in mind when it comes to a salary key.
  • A verifier cannot create a salary key. Instead, they must obtain a salary key from the person whose income information they are trying to verify.
  • A salary key only provides one-time access to a person's income information. If a verifier needs to access a person's income information for a second time (e.g. at a later date) then they will need a new salary key.

How do I create a Salary Key?

For security and privacy reasons, a verifier cannot create a salary key. Only the person whose information is being verified can create a salary key. If you are a verifier and need to instruct your applicant how to create a salary key, please provide them the instructions below.

Please instruct him/her to contact the Client Service Center at 1-800-367-2884. Representatives are available Monday Friday, 7am-7pm CST.

What is an Employer Code?

An Employer Code, also known as a Company Code, is a five-digit number that is used to identify a specific employer on The Work Number database. For example, the employer code for Sears is 10156 while the Employer Code for The Home Depot is 87843. You only need to know what a company's employer code is if you access The Work Number database using the telephone-based system (which can be reached by calling 1-800-367-5690). If you are using the web site, then you can just enter the name of the employer.
