LITTLE RIV prefixes in area code 254

NANPA records 3 assigned NXX blocks to rate center LITTLE RIV in area code 254, 0.4% of the 672 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 MCIMETRO ACCESS TRANSMISSION SERVICES LLC - TX (1), GRANDE COMMUNICATIONS NETWORKS, INC. - TX (1), BRIGHTSPEED OF TEXAS, INC. (1). The earliest assignment on record here is 2008-09-17 and the most recent 2015-07-28. 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 620 – overlay codes cover the same geography, so a rate center is served by all of them.
