FirstBank (Colorado) Routing Number: The Employee-Owned Bank That Refused to Sell

Independent by design, not by accident

FirstBank was founded in 1963 in Lakewood, a suburb immediately west of Denver. Over six decades, as wave after wave of bank consolidation swept through Colorado (Colorado National became US Bank, Vectra became Zions, Guaranty became FirstMerit became Huntington), FirstBank stayed independent. It is now the largest locally owned banking company in Colorado with over $28 billion in assets and more than 100 branches across Colorado, Arizona, and California.

The independence is intentional and structural. FirstBank operates as an Employee Stock Ownership Plan company, meaning employees collectively own a significant stake in the institution. This ESOP structure makes a hostile takeover virtually impossible and removes the short-term shareholder pressure that pushes many community banks to sell to larger acquirers. When FirstBank says it plans to remain independent, the ownership structure backs up the claim.

What employee ownership means for a bank

In an ESOP bank, employees accumulate shares over the course of their careers. When they retire, those shares are bought back by the plan at fair market value. This creates a direct financial incentive for employees to think like owners - to control costs, retain customers, and build long-term franchise value rather than chase quarterly earnings targets. FirstBank employees from tellers to senior executives participate in the same ESOP, aligning incentives across the organization.

The results are measurable. FirstBank has one of the lowest employee turnover rates in Colorado banking, which translates to branch staff who know their customers and communities over years and decades rather than months. The bank consistently ranks at the top of customer satisfaction surveys in the Denver metro area, a market where it competes against national banks with far larger marketing budgets.

Colorado

FirstBank's core market is Colorado's Front Range - the corridor from Fort Collins through Denver to Colorado Springs that contains roughly 85% of the state's population. The bank dominates this market with a branch density that rivals or exceeds the national banks. In recent years, FirstBank has also expanded into Phoenix and several California markets, testing whether the community banking model translates outside of Colorado.

The Colorado market itself has been transformed by population growth. Denver added over 100,000 residents between 2010 and 2020, and the resulting housing boom and commercial development have been central to FirstBank's growth. The bank is one of the largest SBA lenders in Colorado and a major player in commercial real estate lending along the Front Range.

Using routing number 107005047

FirstBank uses routing number 107005047 for all ACH transactions, direct deposits, and domestic transfers. The 107 prefix is assigned by the Federal Reserve Bank of Kansas City, which serves the Colorado banking district. This single routing number applies to all FirstBank accounts across Colorado, Arizona, and California - regardless of which branch holds the account.

For domestic wire transfers, use the same routing number. FirstBank's online banking platform displays your routing and account numbers under account details. On FirstBank checks, the routing number is printed in the bottom-left corner in standard MICR format.

Ownership that aligns with outcomes

FirstBank's ESOP model demonstrates that when the people running the institution have skin in the game, the results speak for themselves. Slash operates with a similar conviction: the companies using the platform should have full visibility and control over their financial operations. Corporate cards with customizable spend controls, real-time expense tracking, and seamless accounting integrations put business owners - not bank executives - in the driver's seat.

For Colorado businesses that value FirstBank's independent, employee-owned ethos, Slash provides a modern complement - the spend management infrastructure that keeps financial operations as lean as the Front Range banks that inspired it.
