McKinney, Texas: a boomtown bank for a boomtown corridor
McKinney, Texas was a quiet Collin County seat of about 50,000 people in 2000. By 2024, its population had tripled to over 200,000, making it one of the fastest-growing cities in America. The catalyst was the northward march of the Dallas-Fort Worth metroplex — as companies like Toyota, Raytheon, and dozens of tech firms relocated to Plano, Frisco, and Allen, residential development pushed into McKinney, Prosper, and Celina. Independent Bank Group planted its headquarters squarely in the path of that growth.
Founded in 2002, Independent Bank is young by banking standards but has grown to roughly $18 billion in assets through organic growth and strategic acquisitions. The bank's growth trajectory mirrors the communities it serves: fast, ambitious, and unapologetically Texan.
Routing number
Independent Bank's routing number is 111993750. The 111 prefix ties to the Federal Reserve Bank of Dallas, reflecting the bank's deep Texas roots. This applies to all personal and business accounts across Texas and Colorado — ACH transfers, direct deposit, bill pay, and domestic wire transfers. For incoming international wires, contact Independent Bank directly for SWIFT code and intermediary bank details. Find the routing number in the Independent Bank app under account details, on the bank's website, or on the bottom-left corner of your checks.
If you were a customer of a bank acquired by Independent, verify your current routing number through the app or online banking — account migrations during acquisitions sometimes change routing numbers, and outdated numbers can cause automated payments to fail.
Acquisitions and Texas growth
Independent Bank's growth has relied heavily on acquiring community banks across Texas and Colorado — BOH Holdings in Houston, Guaranty Bancshares, and several smaller Central and North Texas institutions. Each acquisition brought new markets and deposit bases while introducing the typical friction of account migrations, new platforms, and routing number changes for acquired customers.
Serving the companies relocating to Texas
The corporate relocation wave to Texas — driven by lower taxes, lighter regulation, and lower cost of living — has created a specific banking opportunity. Companies moving from California, New York, and Illinois need local banking relationships, and their employees need mortgages and personal accounts. Independent has positioned itself as the local bank that understands the communities these companies are moving into. It underwrites and holds a substantial portion of its mortgage loans on its own balance sheet rather than selling to the secondary market, giving it flexibility for borrowers who don't fit neatly into automated underwriting models.
Built for the speed of a growing market
Independent Bank understands what fast growth looks like — it has lived it. For the tech companies, startups, and relocating businesses driving the DFW boom, Slash provides the financial operations layer that matches that pace: corporate cards issued instantly to new hires, automated spend controls that scale with headcount, and real-time reporting that keeps finance teams ahead of the growth curve rather than chasing it.
