Questions about this area code

Where is area code 484?

484 is a Pennsylvania area code covering Allentown, Reading and West Chester. NANPA's report lists 786 exchanges in use across 79 rate centres.

Is 484 a mobile or a landline area code?

Both. An area code doesn't decide the line type: mobile, landline and VoIP numbers all use 484, and numbers move between carriers. Check the number itself to see what it is today.

Which area codes overlay 484?

610 has numbers in at least half of the same places as 484, so a new number there can get any of these area codes.

Can you tell me who owns a 484 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.
