WATSEKA prefixes in area code 815

NANPA records 4 assigned NXX blocks to rate center WATSEKA in area code 815, 0.5% 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 (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (1), LEVEL 3 COMMUNICATIONS, LLC - IL (1). The earliest assignment on record here is 2002-02-04 and the most recent 2002-02-04. 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 code 779 – overlay codes cover the same geography, so a rate center is served by all of them.
