Frost Bank in San Antonio: the basics

San Antonio is Frost Bank’s headquarters city. Cullen/Frost Bankers, the parent holding company, is headquartered at Frost Tower, 100 West Houston Street, in downtown San Antonio, a 23-story building that opened in 2019 as the city’s first new downtown office tower in three decades. Frost is the oldest bank in Texas, founded in 1868 by Colonel T.C. Frost as a mercantile and banking firm serving frontier ranchers. It has remained continuously Texas-headquartered and family-influenced for over 150 years (the Cullen and Frost families intermarried in the 19th century, and family members still serve on the board). Frost operates only in Texas, with approximately 200 branches statewide, deliberately avoiding interstate expansion to focus on service depth.

Frost Bank customer service phone numbers

For account questions across all San Antonio locations, Frost’s main customer service number is 1-800-513-7678, available 24 hours a day, 7 days a week with live agents (not just automated systems). This 24/7 live-agent customer service is one of Frost’s signature features and distinguishes it from larger banks that route after-hours calls to recorded menus. Lost or stolen debit cards are handled at the same number, 24/7. Frost Wealth Advisors serves high-net-worth clients through dedicated advisor relationships.

The Frost Bank mobile app handles full-service banking 24/7, including Zelle, mobile deposit, bill pay, and card lock and unlock. Frost has historically avoided some product categories that other large banks promote heavily: Frost does NOT offer student loans, payday-style credit, or aggressive overdraft programs, consistent with its conservative service-first banking philosophy.
