NRICHLDHLS prefixes in area code 817
NANPA records 33 assigned NXX blocks to rate center NRICHLDHLS in area code 817, 4.2% of the 781 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. 13 holders hold those blocks, the largest being SOUTHWESTERN BELL (14), ONVOY, LLC - TX (3), LEVEL 3 COMMUNICATIONS, LLC - TX (3). The earliest assignment on record here is 2001-10-02 and the most recent 2004-12-13. 21 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 682 – overlay codes cover the same geography, so a rate center is served by all of them.
