Overview
INB, formally INB, National Association and commonly styled INB or INB, N.A., is a locally owned, privately held national bank based in Springfield, Illinois. The institution operates a community-banking model focused primarily on central Illinois, while also maintaining loan-production offices in the St. Louis metropolitan area and in Tampa and Miami, Florida. Its physical network includes 13 branches and a remittance-processing center in Illinois. The present-day bank is the second generation of the Illinois National Bank name. The original Illinois National Bank was established in Springfield in 1886. That first institution was sold to First of America Bank in 1989 and adopted the First of America name on February 1, 1990. First of America was later sold to National City Bank in 1997, and National City was subsequently acquired by PNC Bank in 2008. These transactions ended the independent operation of the original Illinois National Bank, although the name and local banking legacy were later revived. In 1999, Springfield investors and former employees of the earlier bank organized a new institution using the INB identity. The second-generation bank opened on June 21, 1999, beginning with a single downtown Springfield branch. It expanded over time across central Illinois, adding locations in communities including Peoria, Bloomington, and Champaign. In 2000, INB acquired a remittance-processing center, which the reference material describes as the largest such center in Illinois outside the Chicago area. The bank also developed loan-production offices beyond its branch footprint, allowing it to originate loans in the St. Louis area and in Florida without establishing a full retail branch network there. INB's service range covers conventional retail and commercial banking needs. Its offerings include checking and savings accounts, certificates of deposit, mortgage lending, other loan products, Individual Retirement Accounts, remittance processing, and tax-preparation services. This combination gives the institution a broader operating profile than a basic deposit-taking community bank, while its ownership and geographic concentration continue to distinguish it from large publicly traded national banking groups. The bank changed its formal legal name in 2019 to INB, National Association. INB, N.A., and INB are used as shorter forms in ordinary references. As described in the available reference material, the brand remains active and continues to combine local branch banking with specialized processing and lending operations.
History
INB's history has two distinct phases. The first Illinois National Bank was founded in Springfield, Illinois, in 1886. It operated as a local banking institution until it was sold to First of America Bank in 1989. On February 1, 1990, the bank assumed the First of America name, ending the original institution's independent use of the Illinois National Bank identity. First of America was sold to National City Bank in 1997, and National City was later sold to PNC Bank in 2008. The current institution emerged from a local effort to restore an independent Springfield bank under the INB identity. In 1999, Springfield investors and former employees of the first Illinois National Bank formed a new bank. The second-generation INB opened on June 21, 1999, with one branch in downtown Springfield. Its ownership structure and local management orientation differentiated it from the larger banking organizations that had absorbed the predecessor institution. Expansion followed gradually. In 2000, INB acquired a remittance-processing center. The center became a significant specialized operation and was described in the reference material as the largest remittance-processing center in Illinois outside the Chicago area. Alongside its processing business, INB expanded its retail branch presence beyond Springfield into other central Illinois markets, including Peoria, Bloomington, and Champaign. The bank ultimately grew to 13 branches in central Illinois. INB also extended its lending reach through loan-production offices rather than relying solely on branches. These offices were established in the St. Louis metropolitan area and in Tampa and Miami, Florida. This structure enabled the bank to pursue lending relationships in additional markets while maintaining its core branch network in Illinois. The bank's business scope developed around a mixture of traditional and specialized financial services. Deposit accounts, certificates of deposit, mortgage lending, and other loans form the conventional banking base. Individual Retirement Accounts add retirement-savings capability, while remittance processing and tax preparation provide services outside ordinary branch deposits and lending. The resulting model combines community-bank relationships with operational specialization. In 2019, the institution formally changed its name to INB, National Association. The shorter forms INB, N.A., and INB are used for most purposes. The available account identifies the bank as active, privately held, locally owned, and headquartered in Springfield. It does not provide a current executive roster, financial figures, official website, or a detailed chronology of individual branch openings, so those fields are not supplied here.
