About the 559 region
559 covers Fresno in California, including Hanford, Madera, Tulare and Visalia. The code has been in service since 1998.
As the Fresno region grew, 559 ran low on available numbers, so 357 was added as an overlay code over the same geographic area. Both codes are local to each other and 10-digit dialing applies throughout.
