TCBK business online banking is the web portal Tri Counties Bank provides to California business customers for daily deposit account management, treasury operations, and payment origination. Branded as Trico Business Express, the online banking portal runs 24/7 on desktop browsers and native mobile apps, secured with multi-factor authentication and 256-bit TLS encryption. This page focuses on online banking capabilities — what the portal handles without a branch visit and where the branch network still plays a role.
Over 30,000 California businesses run their daily banking through TCBK online banking. From a solo proprietor checking balances on the mobile app to a controller uploading a NACHA payroll file from the desktop web portal, the same platform scales across the full range of California commercial customers. Security controls, audit logging, and regulatory oversight apply equally on every access surface.

Capability access depends on role-based permissions in account management and enrolled treasury services. Specific pricing and cutoffs available from Tri Counties Bank at +1-800-922-8742.
Most routine activity runs online; specific tasks still require branch visits. Understanding the split saves time.
Tri Counties Bank operates 75+ branches across Northern and Central California. See customer service for branch locator and in-person banking support.
Online banking security works on multiple layers — transport, authentication, session, and activity monitoring.
256-bit TLS encryption protects every byte between browser or app and Tri Counties Bank servers. Multi-factor authentication combines password with verification code from SMS, email, or authenticator app. Step-up authentication triggers again in-session for high-risk actions — new beneficiary wire transfer, admin changes, large ACH batch. Certificate pinning on the mobile app rejects man-in-the-middle attacks on untrusted Wi-Fi.
Session timeout defaults to 15 minutes of inactivity with an 8-hour ceiling. IP whitelisting restricts login to approved networks. Geo restrictions block countries with no legitimate business reason. Real-time fraud monitoring flags first-time high-value transactions, unusual geography, and atypical patterns. Every action logs to a 7-year audit trail for compliance and regulatory examination by the OCC and California DFPI.
