Questions about this area code
Where is area code 346?
346 is a Texas area code covering Houston. NANPA's report lists 754 exchanges in use across 45 rate centres.
Is 346 a mobile or a landline area code?
Both. An area code doesn't decide the line type: mobile, landline and VoIP numbers all use 346, and numbers move between carriers. Check the number itself to see what it is today.
Which area codes overlay 346?
281 and 832 have numbers in at least half of the same places as 346, so a new number there can get any of these area codes.
Can you tell me who owns a 346 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.
