What is a control number on a w2?

A control number on a W2 form is a unique identifier assigned by the employer to each individual employee. The control number is used for internal tracking and organization purposes, and is often used to differentiate between multiple W2 forms issued by the same employer.

This control number does not have any impact on an individual's taxes or tax filing process. It is simply a way for the employer to keep track of and manage their employees' tax information.

If you have any questions or concerns about the control number on your W2 form, you should contact your employer or human resources department for clarification.
