ARCOLA prefixes in area code 346

NANPA records 7 assigned NXX blocks to rate center ARCOLA in area code 346, 0.9% of the 752 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 - TX (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2), BANDWIDTH.COM CLEC, LLC - TX (2). The earliest assignment on record here is 2016-08-31 and the most recent 2026-09-11. 7 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 217, 260, 281, 417 – overlay codes cover the same geography, so a rate center is served by all of them.
