PORTER HTS prefixes in area code 281
NANPA records 3 assigned NXX blocks to rate center PORTER HTS in area code 281, 0.4% of the 786 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 BRIGHTSPEED OF TEXAS, INC. (2), GRANDE COMMUNICATIONS NETWORKS, INC. - TX (1). 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 codes 346, 832 – overlay codes cover the same geography, so a rate center is served by all of them.
