American Express (Amex) Cards and Payment Services

American Express, widely known as Amex, is a globally recognized financial services corporation. Founded in 1850 in Buffalo, New York, it initially operated as an express mail business before pivoting to financial and travel-related services. Today, it is a premier provider of charge and credit cards, merchant account services, and travel-related benefits.

The brand is fundamentally American and is headquartered in Lower Manhattan, New York City. While the financial processing and digital technologies are managed globally, physical card manufacturing is distributed across multiple countries to serve regional markets and high-security printing requirements. The company operates as a publicly traded entity on the New York Stock Exchange and remains one of the most valuable financial brands in the world.
