Ten-digit and seven-digit dialing in 201
According to NANPA's dialing-plan data, local calls within 201 are dialed as ten digits (area code plus number) and toll calls as ten digits (area code plus number). Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number. NANPA's dialing-plan note for this code reads: "Calls between the 551 and 201 NPAs may be dialed as 10D. 1+10 digit permissible at service provider discretion."
Who holds 201 exchanges
34 carriers hold the 779 central office codes assigned in 201. Verizon New Jersey, INC. has the most, with 266 (34%). 487 of the codes (63%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. The code holder is not necessarily the carrier serving a given number today, since numbers can be ported between providers.
