COOLIDGE prefixes in area code 229

NANPA records 4 assigned NXX blocks to rate center COOLIDGE 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 CITY OF THOMASVILLE (1), WINDSTREAM GEORGIA COMMUNICATIONS CORP. (1), ONVOY, LLC - GA (1). The earliest assignment on record here is 2015-11-09 and the most recent 2015-11-09. 2 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 254, 620 – overlay codes cover the same geography, so a rate center is served by all of them.
