ENGELHARD prefixes in area code 252

NANPA records 6 assigned NXX blocks to rate center ENGELHARD in area code 252, 0.9% 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. 6 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - NC (1), UNITED STATES CELLULAR - NC (1), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2001-05-24 and the most recent 2018-03-27. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
