A W-2 Express employer code is a number used to identify a specific employer that utilizes the W-2 management system for distributing and managing employees' W-2 documents. Employers can also be searched by company name on the log-in page.
W-2 Management is an online tool that helps to streamline and automate the W-2 process. Most of its clients are companies with over 15,000 employees, so they have a large number of W-2s to distribute.
If a person is unsure whether his company works with W-2 Management, he can perform a search on W-2 Management's website or inquire at his place of work.
