Or call the number on the back of your card and ask for the ABA routing number for your account.
Confirm the number with the bank before using it for direct deposit or a transfer.

Before you send

Check these before you send money

Confirm the bank name on the transfer matches Bull Dog.
Match the number to the transfer type — ACH and direct deposit use one number, domestic wires another.
For wires, double-check the recipient's name and address too.
If instructions arrived by email, confirm them on Bull Dog's official site or phone line before sending.
No one should ever need your password or full card number to confirm a routing number — that's a scam.
