How is an individual name control code determined?

The IRS creates name control codes for individuals from the legal name listed on your tax information. Zenefits determines name control codes based on the information employees provide in their profiles.
Valid Characters:

• Numeric (0- 9)
• Alpha (A-Z)
• Hyphen (-)
• Ampersand (&)

Special Rules for Individuals:

• Use the first four characters of the individual’s last name.
