What is meant by the Briefkastenregelung?

The Briefkastenregelung refers to the rules and guidelines governing how mailboxes may be installed, labelled, or modified in residential buildings, to ensure that mail is delivered safely and lawfully and to avoid loss of letters or unnecessary delays.

Who is responsible for the mailbox?

As a rule, the landlord is responsible for providing a suitable mailbox for each residential unit.
The mailbox must be located where the postal worker can easily access it – usually in the entrance area of the building or near the main door.

When might a tenant want to change the mailbox?

A tenant may wish to replace or alter the mailbox for a number of reasons, such as:

• the mailbox is damaged or difficult to use,

• the need to improve security,

• problems with the size or design of the box, for example if it does not match the amount or format of the incoming mail.

Is the tenant allowed to change the mailbox on their own?

No.
A tenant may not change, move, or replace the mailbox without the landlord’s consent, because the mailbox is usually considered part of the common facilities of the property.
The tenant should submit a written request to the landlord, explaining the reasons and the desired specifications of the new mailbox.

What are the legal requirements for a mailbox?

A mailbox should

• be weather-resistant,

• be equipped with a lockable mechanism to protect privacy,

• clearly display the tenant’s name, in order to avoid misdeliveries,

• comply in size and design with the German postal standard DIN EN 13724, so that official and standard-sized letters can be received without problems.

Is the landlord obliged to repair or replace the mailbox?

Yes.
If the mailbox is damaged, defective or no longer usable in practice, the landlord is obliged to repair or replace it to ensure the tenant’s right to receive mail safely and reliably.

What is the legal relevance of the mailbox for official notifications?

Official notifications – such as court letters, notices of termination, or important communications from the landlord – are usually deemed legally received once they have been placed in the correctly labelled mailbox of the tenant.
For this reason, it is extremely important to have a functional mailbox clearly marked with the correct name, in order not to miss legal deadlines or suffer legal consequences.

Practical tips

• Make sure your name (and the names of all occupants, if needed) is clearly written on the mailbox.

• Regularly check the condition of your mailbox and request maintenance or repairs if necessary.

• When you move out, remove or cover your name to avoid receiving mail that is no longer intended for you.

• Keep a spare key to the mailbox in a safe place.

Conclusion

Changing or replacing a mailbox (Briefkastenregelung) in Germany is subject to clear rules designed to protect rights and ensure that mail is delivered safely and reliably. Knowing these rules and following the proper legal procedure when a change is needed helps avoid disputes with the landlord and problems caused by lost mail, and supports a stable and positive tenancy.
