Completing Registration. Subsequent Variations

By means of the administrative decision on registration, the General Treasury of the Social Security will assign the employer a unique registration number, which will be considered to be their primary and main Contribution Account Code. The successive account codes that are created in the same or in different provinces shall be linked to said Contribution Account Code.

Employer registration is unique and is valid in the relevant Social Security schemes, throughout Spanish territory and for the lifetime of the natural or legal person that owns the company.

Employers are required to communicate changes in the details included when registration was completed, within a period of six calendar days from the change, especially if they involve a change of name, address, economic activity, subcontracting of works and services to other companies, etc.

It is also compulsory to provide ten days advance notification of a change in the insurance company providing coverage for occupational contingencies.
