LAKE CITY prefixes in area code 870

NANPA records 3 assigned NXX blocks to rate center LAKE CITY in area code 870, 0.4% of the 785 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 BRIGHTSPEED OF NORTHWEST ARKANSAS, LLC (1), E. RITTER COMMUNICATIONS, LLC (1), METROPCS, INC. (1). The earliest assignment on record here is 2007-01-30 and the most recent 2015-03-12. 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 231, 386, 620, 651 – overlay codes cover the same geography, so a rate center is served by all of them.
