What a c/o address means

"c/o" stands for "care of." A c/o address means that a letter or package is to be delivered to a person who can be reached at the address of another person or institution.

A classic example: You are staying temporarily with your parents and provide your address as "Max Mustermann, c/o Mustermann Family, Musterstraße 1, 10115 Berlin." Mail will be delivered there, even though you are not the actual tenant or owner.

When to use a c/o address

In private life, the c/o address is widely used and practical:

 
• Temporary stays with family or friends
 
• Students living in changing locations
 
• People moving from abroad who do not yet have their own apartment
 
• Temporary absence from your own place of residence

In a business context, a c/o address is sometimes used when a founder does not yet have their own office and wants to use the address of an acquaintance or a law firm. However, this comes with restrictions.

Is a c/o address allowed in a legal notice?

Yes, a c/o address can be used in a legal notice provided it is capable of receiving service of process. This means that official mail must be able to reach that location and be acknowledged. The person whose address you are using must explicitly consent to this use.

In practice, however, there is a problem: if the person or company whose address you are using withdraws their consent or moves, you lose your address immediately. This makes a c/o address an unreliable foundation for a legal notice, which must be accurate in the long term.

Can I use a c/o address for my business registration?

That depends on the local trade office. Some offices accept a c/o address as a business address, while others do not. There is no uniform regulation across the country. If you want to be on the safe side, you should check with the relevant trade office in advance.

For registration in the commercial register for corporations such as a GmbH or UG, a c/o address is generally not accepted. The registry court requires a clear, permanently valid address for service of process.

The limitations of a c/o address for companies

A c/o address has several weaknesses in a business context:

 
• Dependence on third parties: You are reliant on the other person to reliably forward mail and to permit its use on a permanent basis.
 
• Lack of professionalism: A c/o address appears less professional to the outside world than an independent business address.
 
• Limited use: Banks and some authorities do not accept c/o addresses for all purposes.
 
• Commercial register: Usually not usable for GmbH and UG companies.
 
• Lack of control: You cannot be certain that mail is actually arriving and being forwarded.

The better alternative: A professional business address

Anyone needing a reliable, independent, and permanently usable address is better off with a professional business address than with a c/o solution. The difference in price is minimal, but the difference in security and professionalism is significant.

Bottom line: c/o is a solution, but not the best one

A c/o address can help in the short term, but it is not a sustainable solution for building a serious business. It depends on the reliability of third parties, is not accepted by some institutions, and can appear unprofessional to others.
