ARCOLA prefixes in area code 217

NANPA records 5 assigned NXX blocks to rate center ARCOLA in area code 217, 0.6% 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. 5 holders hold those blocks, the largest being ILLINOIS CONSOLIDATED TEL. CO. (1), MEDIACOM TELEPHONY OF ILLINOIS, LLC - IL (1), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2001-11-09 and the most recent 2023-04-11. 5 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 260, 281, 346, 417 – overlay codes cover the same geography, so a rate center is served by all of them.
