# California Area Code 562
The 562 area code serves Long Beach and surrounding communities in Los Angeles County, California. Established in 1997 as a split from the 310 area code, the 562 area covers a significant portion of southeastern Los Angeles County, including cities such as Long Beach, Lakewood, Cerritos, Norwalk, and Downey. This densely populated region required its own dedicated area code due to rapid growth and increasing demand for telephone numbers throughout the 1990s. The 562 area code has become an integral part of the region's telecommunications infrastructure, serving hundreds of thousands of residents and businesses in one of Southern California's most vibrant areas.
The North American Numbering Plan (NANP) is the system responsible for designating area codes like 562 throughout North America. Administered by the North American Numbering Plan Administration (NANPA), this system organizes telephone numbers into a hierarchical structure consisting of area codes, exchange codes, and subscriber numbers. When population growth or economic development creates insufficient available phone numbers within an existing area code, NANPA authorizes the creation of new area codes through a process called "area code splitting." The 562 area code exemplifies this process, as telecommunications regulators recognized that the original 310 area code could not accommodate Long Beach's growing population and business expansion, making a new dedicated area code necessary to ensure adequate numbering resources for the region's continued development.
