Corresponsal Bancario Bancolombia is a service that allows individuals to perform basic banking transactions through authorized third-party agents, such as local shops and businesses. These agents enable people to make payments, withdraw cash, check balances, and deposit money, offering convenient banking access in areas where physical branches might be scarce. The service is designed to extend the reach of Bancolombia, making financial services more accessible and inclusive across Colombia, especially in rural and underserved regions.
