GILMER prefixes in area code 903

NANPA records 4 assigned NXX blocks to rate center GILMER in area code 903, 0.5% of the 771 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. 3 holders hold those blocks, the largest being FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (1), ETEX COMMUNCATIONS, LLC DBA ETEX TELECOM - TX (1). The earliest assignment on record here is 2001-01-08 and the most recent 2010-01-20. 3 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 code 430 – overlay codes cover the same geography, so a rate center is served by all of them.
