First Horizon Routing Numbers in Louisiana

First Horizon has 48 routing numbers registered in Louisiana. When setting up direct deposit, bill pay, or wire transfers, make sure to use the routing number assigned to your specific branch or account — using the wrong one can delay or reject your transaction.

Your routing number appears on the bottom-left of any First Horizon check, in the First Horizon mobile app under account details, or by calling First Horizon at 866-447-8048. For ACH transfers like direct deposits and bill payments, use your state-specific routing number. For domestic wire transfers, First Horizon may use a different number — always confirm with the bank before sending a wire.

The reason First Horizon has multiple routing numbers in Louisiana is typically due to historical mergers and acquisitions. When banks merge, the acquired institution's routing numbers are often preserved so existing customers don't need to update their direct deposits, autopayments, and vendor relationships. Each routing number is tied to a specific Federal Reserve processing center.

All First Horizon routing numbers in Louisiana can be used for ACH transactions, direct deposits, and electronic payments. They are processed through the Federal Reserve and are verified using the standard ABA checksum algorithm.
