ALTON prefixes in area code 618
NANPA records 15 assigned NXX blocks to rate center ALTON in area code 618, 1.9% 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. 4 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (9), NEW CINGULAR WIRELESS PCS, LLC - IL (3), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2014-11-21 and the most recent 2022-12-08. 11 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 207, 380, 417, 603 – overlay codes cover the same geography, so a rate center is served by all of them.
