Apply for employer identification number

Whenever you have to submit a notification to the social security authorities (for example, registering employees), you need an employer identification number. The employer identification number must be given in any notifications to the health insurance company and also in communications between companies subject to fast-track registration and the DRV (German statutory pension insurance scheme).
