Your employer's federal identification number is the employer identification number. The best place to look for your employer's EIN (Employer Identification Number) or Tax ID is in Box b of your W-2 form. Look for a 9-digit number with a dash separating the second and third digit (NN-NNNNNNN). It's usually right above your employer's name or below their address.
