Bank routing numbers in Walnut Creek, California

About banking in Walnut Creek

Walnut Creek, California hosts the registered FedACH offices for 8 bank and credit union routing numbers. The list above includes the primary RTN for each registered office at a Walnut Creek street address — typically a head office, an operations center, or a major retail branch through which a community institution clears its ACH and wire activity.

For most personal customers, the routing number tied to your account is the same number listed here as long as your account was opened at one of the institutions with a registered Walnut Creek office. If you opened your account in another city or state, your routing number is tied to that location instead — moving to Walnut Creek does not change the routing number on file with your bank.

Use the right number for the right payment

The routing numbers listed above support the standard ACH suite — direct deposit, automatic bill-pay, IRS tax refunds, Social Security payments, and external account linkage at brokerages and payment apps. For incoming Fedwire transfers, contact your specific bank to confirm the wire RTN, which can differ from the per-state ACH number for some larger institutions.
