Before you send

Check these before you send money

  • Confirm the bank name on the transfer matches San Diego County.
  • 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 San Diego County'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.
