FAQs
Common questions about ACH and wires through Northwest Bank
Why does Northwest Bank have only one routing number while other banks have multiple?
Northwest Bank simplified its operations by maintaining a single routing number (243374218) across all states. This approach makes banking easier for customers who move between states or manage accounts in different locations. The bank achieved this through careful consolidation during its numerous acquisitions, including Ridgway Federal Savings in 1983, Bridgeville Savings Bank in 1997, and most recently the 2020 acquisition of MutualBank in Indiana and the 2025 merger with Penns Woods Bancorp.
Can I use the same routing number if I move from Pennsylvania to New York?
Yes, absolutely. One of the major benefits of Northwest Bank's single routing number system is that you can move anywhere within their service area (Pennsylvania, New York, Indiana, or Ohio) and continue using the same routing number: 243374218. You won't need to update your direct deposit, automatic payments, or any other banking information when you relocate.
What's the difference between ACH and wire routing numbers at Northwest Bank?
Northwest Bank uses the same routing number (243374218) for both ACH transfers and wire transfers. However, fees differ significantly. ACH transfers are typically free and take 1-3 business days to process, while wire transfers cost $25 for domestic outgoing wires and process same business day. For international wires, you'll also need Northwest Bank's SWIFT code: NWBIUS33.
