Questions about this area code
Where is area code 707?
707 is a California area code covering Santa Rosa, Napa and Vallejo. NANPA's report lists 786 exchanges in use across 75 rate centres.
Is 707 a mobile or a landline area code?
Both. An area code doesn't decide the line type: mobile, landline and VoIP numbers all use 707, and numbers move between carriers. Check the number itself to see what it is today.
Which area codes overlay 707?
None in NANPA's current report: no other area code has numbers in half of 707's rate centres.
Can you tell me who owns a 707 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.
