Click on other accounts under the Transfers Tab. Select the add My external account link to the right of the external Transfer accounts panel and follow the prompts. After you complete the online form, two small deposits and one withdrawal transaction will be sent to your External Account. You must verify the small deposits to confirm you are an authorized owner of that account.
Note: In order to add the External Account, you must be an owner of that account, know the account number and the account type (checking or savings), and verify that you can access the account. Please allow 1–2 business days for the two small deposits and withdrawal transaction to process at your other financial institution.
