Getting a bank accountFor opening a bank account you have to show your passport. Since most banks do not charge students for account-keeping we recommend taking your student ID and the "Meldebescheinigung" from the resident's registration office with you. Those documents can in most cases be submitted later on.
Before opening an account you should ask the bank about the credit regulations. A credit facility is included in a normal giro account (Girokonto). This means that you can overcheck the account up to a certain limit. Since you as a student may not have very much money and since the bank charges high interest rates for this credit, overchecking your account can be costly. Find a credit limit, which is acceptable for your income, and ask the bank to store this limit on your account.
You can choose from a variety of banks.
