Finding your employer's Employer Identification Number (EIN)

In order to approve your request for paid family or medical leave, the Department of Family and Medical Leave will need some information about your employer.

Your employer’s Employer Identification Number (EIN) is a unique number assigned to a business entity so it can be easily identified by the Internal Revenue Service. EINs are most commonly used to report taxes.

The easiest way to find your employer’s EIN is to look in box B of your W-2 form, right above your employer’s name and address. The EIN is most likely a 9-digit number, with a dash separating the first 2 digits: XX-XXXXXXX. If you don’t have this year’s W-2 form yet but you worked for the same employer in previous years, you can look on a past year’s W-2 form - your employer’s EIN will not have changed.

If you don’t have a W-2 form, try asking your employer for their EIN. We recommend reaching out to your employer’s payroll, accounting, or human resources departments first.
