View detailsSmall-town headquarters, big regional reach
Banner Bank is headquartered in Walla Walla, Washington — a city of roughly 34,000 people known for sweet onions, a dense concentration of wineries, and Whitman College. It's an unusual home base for a bank with over $15 billion in assets and branches spanning Washington, Oregon, Idaho, and California. But Banner's Walla Walla roots are inseparable from its identity as a bank that grew up serving agricultural communities, small businesses, and rural towns across the inland Pacific Northwest.
Routing number
Banner Bank's routing number is 125008013. The 125 prefix ties to the Federal Reserve Bank of San Francisco's Seattle processing center. This applies to all personal and business accounts — ACH, direct deposit, bill pay, and domestic wire transfers. For incoming international wires, confirm the SWIFT code directly with Banner, as it may change during the Columbia Banking System integration. Find the routing number in the Banner Bank mobile app under account details, or on the bottom-left corner of a check. When in doubt, call 1-800-272-9933.
Agricultural banking and the cycles of the land
The Pacific Northwest's agricultural economy — wheat, apples, cherries, wine grapes, hops, potatoes — runs on credit cycles most urban banks don't understand. Farmers need operating lines of credit in the spring, equipment financing that aligns with harvest schedules, and deposit products that accommodate the feast-or-famine cash flow of commodity agriculture. Banner built its early reputation underwriting these credits with genuine agronomic knowledge, employing loan officers who could assess a wheat yield estimate or evaluate an orchard's productive life. That expertise extended naturally into food processing, cold storage, farm equipment dealerships, and the logistics companies that move Pacific Northwest agricultural products to market.
The Columbia Banking System merger
In January 2023, Columbia Banking System completed its merger with Umpqua Holdings, creating a combined institution with over $50 billion in assets and the largest community bank footprint in the Pacific Northwest. Banner Bank operates within this broader ecosystem. As of now, Banner continues to operate under its own name and routing number 125008013 remains active. Monitor communications from Banner regarding any future account migrations or routing number changes as the integration progresses.
Financial infrastructure beyond the branch network
Banner's strength is its deep understanding of Pacific Northwest industries and the communities it serves. For businesses that need financial tools matching the speed of modern operations — instant virtual card issuance, automated receipt matching, and real-time spend controls across teams — Slash provides business banking infrastructure that complements a strong local banking relationship. No branch visit required, no harvest cycle wait times.
