IBC Bank Routing Number: Border Banking Between Two Economies

The bank Laredo built

International Bank of Commerce was founded in 1966 in Laredo, Texas — a city where 95% of the population is Hispanic and the economy is inseparable from cross-border trade with Nuevo Laredo, Mexico. IBC was created to serve a community that mainstream Texas banks largely ignored: Spanish-speaking families and businesses whose economic lives straddled the international boundary. Founder Dennis E. Nixon remains chairman and CEO more than five decades later, making IBC one of the few major American banks still led by its original founder.

Today IBC operates over 170 branches across Texas and Oklahoma, with additional operations in Mexico through affiliate banks. The holding company, International Bancshares Corporation, manages roughly $15 billion in assets.

Routing number

IBC Bank's routing number is 114902528. The 114 prefix ties to the Federal Reserve Bank of Dallas, marking it as a Texas-chartered institution. This applies to all domestic transactions — ACH transfers, direct deposit, bill pay, and domestic wire transfers — regardless of which Texas or Oklahoma branch holds your account. For international wire transfers involving IBC's Mexican affiliate operations, additional correspondent bank details may be required; contact IBC's international banking division for specific instructions. Find the routing number on the bottom-left corner of IBC checks, through online banking, or in the IBC Bank mobile app.

Cross-border trade finance

The US-Mexico border economy moves over $700 billion in bilateral trade annually, and Laredo is the single busiest inland port in the Western Hemisphere. Thousands of companies depend on moving goods and money across the border efficiently — paying Mexican suppliers in pesos, receiving payments from American buyers in dollars, financing inventory in customs warehouses, and managing currency risk on every transaction. IBC built its commercial banking division around these needs: international letters of credit, foreign exchange services, trade finance facilities, and correspondent banking relationships with Mexican financial institutions. For a logistics company clearing 50 trucks a day through the World Trade Bridge, IBC is a critical piece of supply chain infrastructure.

Largest minority-owned bank in Texas

IBC is the largest minority-owned commercial bank in Texas — a regulatory classification based on ownership structure and board composition, not a marketing designation. It qualifies IBC for Community Development Financial Institution programs and Minority Depository Institution initiatives that channel federal resources toward underserved communities. Many IBC branches are in small border towns — Eagle Pass, Del Rio, Roma, Zapata — where IBC may be the only full-service bank available.

Modern business banking for companies that move fast

IBC's cross-border expertise shows what happens when a bank truly understands its customers' operations. Slash brings that same depth to business spend management — unlimited virtual cards for vendor payments, real-time transaction alerts, and accounting integrations that cut manual reconciliation so finance teams can focus on work that actually grows the business.
