First Horizon Bank

First Horizon Bank traces its lineage to First National Bank of Memphis, chartered in 1864, making it one of the oldest banking institutions in the South. For most of its history it operated primarily in Tennessee, but a series of acquisitions — most significantly the 2022 merger with IBERIA Bank, itself a Louisiana institution with a long regional history — expanded First Horizon's footprint across the Southeast substantially. Today the bank serves retail and commercial customers across Tennessee, Louisiana, Florida, Mississippi, Alabama, and the broader mid-South region with a full suite of commercial and consumer banking services.

First Horizon's digital banking platform handles retail and commercial banking through a web portal and mobile app that have been progressively unified following the IBERIA merger. Retail customers rely on the standard digital banking toolkit: account access, transfers, bill pay, and mobile check deposit. Commercial customers use ACH origination, wire transfer, and cash management features to manage business finances. The merger integration process — combining two large banking platforms with different core banking systems — has been a significant technology undertaking that has at times affected platform reliability during transition periods.

When First Horizon's online banking systems go down, customers encounter problems that have become familiar in the context of a bank managing a large merger integration. Login authentication fails or the portal loads but cannot retrieve account data. ACH transfers sit in a processing state past their expected posting time. Bill pay scheduled payments may not send confirmation emails, leaving customers uncertain whether payment instructions were accepted. The mobile app fails to connect to the banking backend, returning generic error messages that don't indicate whether the problem is local or system-wide. Mobile check deposit is unavailable when the image processing backend is degraded.
