Where is my Employer Id Number?
By law each employer must have an Employer Identification Number (EIN). This is
a unique number for each employer and is assigned by the federal government. A sole-proprietor
may opt to provide their Social Security Number (SSN) in place of an EIN.
The EIN you enter to register for online access must match the EIN that SAIF has
on file for your company.
If you need an EIN, please refer to the IRS site on how to Apply for an EIN.
