Ten-digit and seven-digit dialing in 616
According to NANPA's dialing-plan data, local calls within 616 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. 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: "1+10 digit permissible at service provider discretion."
Who holds 616 exchanges
52 carriers hold the 545 central office codes assigned in 616. Michigan Bell Tel CO has the most, with 142 (26%). 357 of the codes (66%) 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.
