Notice for Check and Electronic or ACH Payments Users

If you write checks that are processed electronically, you may be contacted for approval or the check may be rejected due to the routing number change. A routing number change confirmation form can be found here. This form will serve to confirm NWSB Bank's routing number change necessitated by the recent merger with ACNB Bank. If you order checks from a 3rd party provider as opposed to NWSB Bank, please be aware that the bank name and logo may be printed as ACNB Bank as opposed to NWSB Bank.

Also, when making or setting up electronic payments, please use our new routing number, 031309945

If you have questions or concerns regarding this information, please contact us at 1-844-822-6972.
