RICHLAND prefixes in area code 229

NANPA records 4 assigned NXX blocks to rate center RICHLAND in area code 229, 0.6% of the 685 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. 4 holders hold those blocks, the largest being ONVOY, LLC - GA (1), LEVEL 3 COMMUNICATIONS, LLC - GA (1), VONAGE AMERICA LLC (1). The earliest assignment on record here is 2006-01-19 and the most recent 2018-03-23. 4 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 269, 319, 430, 509 – overlay codes cover the same geography, so a rate center is served by all of them.
