Gusto will assign each employee a unique identifier called the "Gusto employee ID." This is a 6-character alphanumeric ID (e.g. 5G9934) that gets securely generated and randomly assigned. This is to enable a better distinction of employees for accurate payments and record keeping.
The Gusto employee ID can be found in a few places in your account—under the "Personal" tab of an employee’s profile, and as an optional field in the CSV template on step 1 while running payroll. Learn more about how CSV uploads work here.
At this time, Gusto employee IDs are not customizable and cannot be disabled.
