Effective Oct. 20, Commerce Bank of Kansas merged with Commerce Bank of Missouri resulting in a new bank routing number for Commerce Bank of Kansas customers. Because many WSU faculty, staff and students bank with Commerce Bank of Kansas, a mass update was performed to update the routing number in our Payroll and Accounts Receivable systems. Therefore, if you bank with Commerce Bank of Kansas and received a notice from them regarding a bank routing number change, you do not need to contact the WSU payroll or accounts receivable departments with this information. Questions? Call payroll 978-3074 or accounts receivable at 978-3333.
