CHANDLER prefixes in area code 812

NANPA records 5 assigned NXX blocks to rate center CHANDLER in area code 812, 0.6% 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. 5 holders hold those blocks, the largest being RCN TELECOM SERVICES OF ILLINOIS, LLC (1), PAETEC ITEL, LLC (1), INDIANA BELL TEL CO INC (1). The earliest assignment on record here is 2006-03-01 and the most recent 2024-01-30. 3 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 405, 507, 572, 903 – overlay codes cover the same geography, so a rate center is served by all of them.
