Company number for social security declarations assigned on request Unfortunately this specification of service has not yet been completely translated.

As an employer, you must register your employees for social insurance. To do this, you need a company number.

As soon as you employ the first person who is subject to compulsory insurance, you must apply for a company number for the company in which the person is employed.

The company number is usually assigned by the Federal Employment Agency upon electronic application. A customer data record is created for you in which your company master data is registered. On the basis of the company number, the social insurance agencies can then allocate the notifications to the health, pension and unemployment insurance to your company of employment.

One or more company numbers?

  • If you are the employer of an enterprise with only one location, you only need 1 establishment number.
  • You will need several establishment numbers if you have establishments in several municipalities.
  • You also need several establishment numbers if you are the owner of several establishments (as separate economic units).

Head office abroad

If you are an employer based abroad, you may need a company number - if you have to report workers employed in Germany to the German social insurance system. This could be, for example, sales staff or customer service staff working from a home office.
