Questions developers ask
- Where is area code 646?
- Area code 646 is in New York, in the United States: all 800 of its exchanges on record are there. From abroad it is dialled +1 646, then the seven-digit number.
- Is a 646 number mobile or landline?
- Either: in the North American Numbering Plan the line type belongs to the exchange (the three digits after the area code), not to the area code. Of the 800 exchanges on record in 646, 378 (47%) were allocated as mobile, 342 (43%) as fixed line, 65 (8%) as VoIP and 15 (2%) have no line type on record. A number can have been ported since, to another carrier and even to another line type.
- Which carriers have numbers in area code 646?
- 32 carriers hold exchanges in 646 on record; the most: Verizon (228), T-Mobile (212) and AT&T (91). These are the original allocations: with number portability, a number may be served by another carrier today, which only a live carrier lookup (an HLR or MNP query) can tell.
- How do I validate a 646 phone number?
- In E.164 a 646 number matches ^\+1646[2-9]\d{6}$: +1, the area code, a central office code that does not start with 0 or 1, then four digits. Written nationally it reads (646) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
