Company number for social security notifications assigned on request

    As an employer, you must register your employees who are subject to social insurance contributions. You will need a company number for this.

    Description

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

    The company number is usually issued by the Federal Employment Agency upon electronic application. A customer data record is created for you in which your company master data is registered. The social insurance institutions can then use the company number to assign the notifications to the health, pension and unemployment insurance schemes to your employment company.

    One or more company numbers?

    • As the employer of a company with only one location, you only need one company number.
    • You will need several company numbers if you have branches in several municipalities.
    • You also need several establishment numbers if you are the owner of several establishments in the same municipality, each of which forms an independent economic unit.

    Registered 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 security system. This could be sales staff or customer advisors working from home, for example.

    Special rules for private households, miners and shipping companies

    • You want to employ someone in your private household on a marginal basis (mini-job): Please contact the mini-job center of the German pension insurance Knappschaft-Bahn-See.
    • You are a miner's company (extraction of minerals, e.g. coal), employ staff in a miner's company or employ workers who carry out miner's work in mines or are used for remediation work in opencast mines: Please contact Deutsche Rentenversicherung Knappschaft-Bahn-See.
    • You are a seafaring company (including coastal fishermen and coastal skippers): Please contact Deutsche Rentenversicherung Knappschaft-Bahn-See.

    Please apply for your company number electronically. You can submit the application yourself or commission someone else to do so, for example a tax consultant.

    Note: If there are changes to the master data or the business closes, you must notify the Federal Employment Agency electronically without delay.

    • meat industry
    • prostitution industry,

    Application deadline: 6 weeks (As a rule: As an employer, you must register employment subject to compulsory insurance within 6 weeks of starting. You will need a company number by then at the latest.)

    Notes (specifics)

    Please always use the company number of the company in which the employee concerned actually works in the social security notifications. If there are any changes to the company master data provided when submitting the application, please submit the correct information to the Federal Employment Agency electronically without delay by entering it in your payroll accounting program or using a completion aid. Incorrect use of the company number or late/failed notification of changes may constitute an administrative offense.
