Find your NSB Bank routing number

Where to look: a check, online banking, the mobile app.

  1. Look at the bottom-left of a NSB Bank check — the first 9 digits are your routing number.
  2. Or sign in to online or mobile banking and open your account or routing details.
  3. Or call the number on the back of your card and ask for the ABA routing number for your account.
  4. 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 NSB Bank.
  • 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 NSB Bank'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.
