Banco Popular de Puerto Rico and Popular Bank are closely related sister entities operating under the same parent holding company, Popular, Inc., but they function across distinct geographic markets and legal jurisdictions. Banco Popular de Puerto Rico serves as the primary chartered commercial banking institution operating throughout Puerto Rico and the US Virgin Islands. In contrast, Popular Bank acts as the mainland United States operating subsidiary, maintaining physical branches across select states such as New York, New Jersey, Florida, and California to serve mainland clients.
