Where to file
You can file European patent applications 
with the EPO in Munich, its branch at The Hague or its sub-office in Berlin, but not at its sub-offices in Vienna and Brussels. 
with the central industrial property office or other competent authority of a contracting state if the law of that state so permits or prescribes. 
Divisional applications must however be filed direct with the EPO. 
The most popular way of filing European patent applications is online (see point 106). More than 90% of all European patent applications are filed in this way.
If you decide not to file online, the EPO's addresses are given in Annex IV. The addresses of the national patent authorities and national provisions of the contracting states governing compulsory or optional filing of European patent applications with such authorities are given in "National law relating to the EPC" (see point 4).
