Here’s the first timing step: Open your new account before you close the old account. You’ll want to have the new account ready to go, complete with debit card and checks, before you drop your old bank.
Most banks require identification forms in order to open an account. These include a valid photo ID such as a driver’s license or passport, your Social Security number or alien registration number, and proof of your address.
If you’re going to do an electronic funds transfer (EFT) to open the new account with money from your old account, you’ll need your old account number and the bank’s routing number, which can be found on the bottom of your checks.
