Northwest Bank Routing Numbers by State

Northwest Bank makes banking simple by using a single routing number for all states where it operates. Unlike many regional banks that maintain different routing numbers for each state, Northwest Bank uses one primary routing number across its entire network.

Primary Routing Number (All States): 243374218

This routing number works for all Northwest Bank customers in:

Pennsylvania (78 branches)

New York (27 branches)

Indiana (20 branches)

Ohio (10 branches)

Important Note: Whether you opened your account in Erie, Pittsburgh, Buffalo, Indianapolis, or Columbus, you'll use the same routing number: 243374218. This applies to all transaction types including ACH transfers, wire transfers, direct deposits, bill payments, and electronic transfers.

Headquarters Location:

Northwest Bank is headquartered in Warren, Pennsylvania, at 301 Second Avenue. The bank was originally founded in 1896 as Northwest Mutual Savings Association and has grown through strategic acquisitions to become one of the leading regional banks in the Northeast and Midwest.

Recent Changes: In July 2025, Northwest Bank merged with Penns Woods Bancorp, adding Jersey Shore State Bank and Luzerne Bank locations across North Central and Northeastern Pennsylvania. This brought the total to 151 branches across four states. Despite this expansion, the bank continues to use the single routing number 243374218 for all locations.

Frequently Asked Questions About Northwest Bank Routing Numbers

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.

How do I verify my Northwest Bank routing number?

You can verify your routing number in several ways: check the bottom left corner of your Northwest Bank checks where the routing number 243374218 appears, log into Northwest Online Banking and view your account details, call Northwest customer service at 1-877-672-5678, or visit any Northwest Bank branch. The routing number is always 243374218 regardless of which state you opened your account in.

Can I use Northwest Bank routing numbers for international transfers?

The routing number 243374218 only works for domestic U.S. transfers. For international wire transfers, you need Northwest Bank's SWIFT code: NWBIUS33. International wires must include both the SWIFT code and your account number. These transfers cost $40 per outgoing wire and typically take 1-5 business days to process. All international wire transfers must be initiated in person at a Northwest Bank branch or through Northwest Online Banking.
