Important Note About Legacy Routing Numbers
Due to Prosperity Bank's extensive history of acquisitions, some customers may have accounts with legacy routing numbers from previously acquired banks. If you opened your account at a bank that was later acquired by Prosperity Bank (such as FirstCapital Bank, LegacyTexas Bank, or American State Bank), your original routing number may still be active.
Legacy Routing Numbers:
While Prosperity Bank has consolidated most operations under routing number 113122655, the following legacy routing numbers remain active for customers of acquired institutions:
- Various legacy numbers from acquired banks
- FirstCapital Bank accounts (transitioned to 113122655 in May 2023)
- Former bank acquisitions throughout Texas and Oklahoma
If your checks show a routing number different from 113122655, that number will continue to work for your existing automatic payments and direct deposits. However, for new transactions, Prosperity Bank recommends using the primary routing number 113122655.
Prosperity Bank's Growth Through Acquisitions
Prosperity Bank has one of the most aggressive acquisition strategies in Texas banking. Founded in 1949 as First National Bank of Edna, the bank relocated to El Campo in 1992 and adopted the Prosperity Bank name in 2001. Since then, the bank has grown exponentially through strategic acquisitions:
Major Acquisitions:
- Union State Bank (1998)
- Franklin Bank (2008)
- American State Bank (2012) - Added 37 branches and first West Texas locations
- First Federal Bank Texas (2013)
- First Victoria National Bank (2013) - Added 34 branches
- F&M Bancorporation (2014) - First Oklahoma expansion
- LegacyTexas Bank (2019) - Massive $10+ billion acquisition
- FirstCapital Bank (2023)
- Lone Star State Bank of West Texas (2024)
Despite this rapid growth, Prosperity Bank has worked to consolidate routing numbers to simplify banking operations. The primary routing number 113122655 serves as the unified routing number for most customer transactions.
