Questions about this area code
Where is area code 904?
904 is a Florida area code covering Jacksonville. NANPA's report lists 782 exchanges in use across 19 rate centres.
Is 904 a mobile or a landline area code?
Both. An area code doesn't decide the line type: mobile, landline and VoIP numbers all use 904, and numbers move between carriers. Check the number itself to see what it is today.
Which area codes overlay 904?
None in NANPA's current report: no other area code has numbers in half of 904's rate centres.
Can you tell me who owns a 904 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.
