Before you send

Check these before you send money

  • Confirm the bank name on the transfer matches Armstrong 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 Armstrong 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.
FAQ

Armstrong Bank routing number FAQ

What is Armstrong Bank's routing number?

Armstrong Bank's ACH and direct-deposit routing number depends on the U.S. state where you opened your account. For domestic wires, Armstrong Bank uses 103 104 528 (cross-checked against public directories — confirm before you send). The 9-digit routing number identifies the bank on a transfer; your account number identifies you.

Does Armstrong Bank's routing number depend on my state?

Yes. Armstrong Bank assigns ACH and direct-deposit routing numbers by the U.S. state where you opened your account. Check the bottom-left of a Armstrong Bank check, your account details in online or mobile banking, or the routing-number table on this page to find the one for your state. Domestic wires use a single routing number regardless of state.

What's the difference between Armstrong Bank's ACH and wire routing numbers?

Use the ACH and direct-deposit number for payroll, direct deposit, and everyday transfers. Use the wire number for domestic wire transfers, which also need the recipient's name and address. The two are not interchangeable — sending an ACH payment with a wire routing number (or the reverse) can be rejected, so match the number to the transfer type.

How do I find my Armstrong Bank routing number?

Your routing number is the first 9 digits in the bottom-left of a Armstrong Bank check, or in your online and mobile banking under account or routing details. If anyone asks for your online-banking password or full card number to "verify" a routing number, it's a scam — a routing number alone is public.

Armstrong Bank is a bank headquartered in Muskogee, OK.
