SIMSBURY prefixes in area code 860
NANPA records 16 assigned NXX blocks to rate center SIMSBURY in area code 860, 2.0% of the 783 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 7 holders hold those blocks, the largest being SOUTHERN NEW ENGLAND TELCO DBA FRONTIER COMM OF CT (6), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3), COMCAST IP PHONE, LLC (2). 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
