Questions about this area code
Where is area code 559?
559 is a California area code covering Fresno, Visalia and Clovis. NANPA's report lists 785 exchanges in use across 60 rate centres.
Is 559 a mobile or a landline area code?
Both. An area code doesn't decide the line type: mobile, landline and VoIP numbers all use 559, and numbers move between carriers. Check the number itself to see what it is today.
Which area codes overlay 559?
None in NANPA's current report: no other area code has numbers in half of 559's rate centres.
Can you tell me who owns a 559 number?
No. NumberLookup shows whether a number is valid, its line type, its carrier and its region, never the person or business behind it.
Source: NANPA's public central office code and thousands-block reports, refreshed weekly. Carriers are the ones the numbers were assigned to, not necessarily today's, and never the person who uses a number.
