In order to open a bank account, there are certain documents required which may vary depending on the type of account being opened and the financial institution. Generally, a government-issued identification document such as a passport or driver's license is necessary, along with proof of address such as a utility bill. Additionally, some banks may require employment verification or social security numbers for tax purposes. Another important factor to consider when opening a bank account is the minimum balance requirement. This refers to the amount of money that must be deposited and maintained in the account at all times in order to avoid fees or penalties. It is important to research different banks and their specific requirements in order to choose an account that best suits one's needs and financial situation.
