WINDSOR prefixes in area code 252

NANPA records 7 assigned NXX blocks to rate center WINDSOR in area code 252, 1.0% of the 695 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 UNITED STATES CELLULAR - NC (1), MCC TELEPHONY LLC (1), LEVEL 3 COMMUNICATIONS, LLC - NC (1). The earliest assignment on record here is 2002-09-19 and the most recent 2023-11-27. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 217, 369, 440, 607 – overlay codes cover the same geography, so a rate center is served by all of them.
