GLENHAM prefixes in area code 605

NANPA records 3 assigned NXX blocks to rate center GLENHAM in area code 605, 0.4% of the 745 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. 2 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SD (2), VALLEY TELECOM COOP. ASSN., INC. (1). 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
