Opening a money market is as easy as choosing which bank and account is right for you. Some money market accounts don’t have a minimum opening balance requirement, so you won’t have to worry about keeping a certain amount in the account or incurring a maintenance fee. Compare the top APY accounts with the minimum balance that you’re comfortable with to make the best decision for your saving needs. Prior to opening a money market account online you’ll want to: Have your government-issued photo identification with you. Be prepared, if needed, to lift a security freeze on your credit file to open the account. Have your routing number and account number handy for the account you’re using to fund this new account. Have your social security number available. Almost all of this information may also be needed if you open a new account in person. You may need cash or a check (or checks) to fund a new account opened in a branch.
