What Everyone’s Missing: Less Obvious Routing Details for First Horizon

Many customers focus only on the primary routing number but overlook these critical details:

1. Branch-Specific Routing Numbers
First Horizon operates in multiple states, and some branches may use alternate routing numbers for local processing. For example, First Horizon West Loop (Indianapolis) or Citibank branches merged under First Horizon might have distinct routing codes based on geography or internal systems. Using the wrong branch number can cause delays.

2. Routing Numbers by Transaction Type
While 111000407 covers broad ACH transfers, some digital payment platforms or regional processors may require specific routing codes tied to payment type—e.g., wire transfers, domestic wire (SWIFT: 0112US37), or wire-to-account capabilities. Always confirm if you’re sending money internationally or via specialized services.

3. Routing Number Updates & Regional Changes
Banks occasionally update routing numbers due to mergers, technological upgrades, or compliance needs. First Horizon has undergone significant transformations, including integration with Star Financial and changes across state lines. Customers relying on outdated routing info risk failed transactions. Check with your branch or First Horizon’s official channels for the most current routing details.
