The region is known for its cultural diversity, historic architecture, and strong Asian American communities. Pasadena, the most prominent city in the 626 area, hosts the famous Rose Parade and Rose Bowl each year. The 626 area code has become a cultural marker, often celebrated in media, cuisine, and events like the 626 Night Market.
