WOODSTOCK prefixes in area code 815
NANPA records 28 assigned NXX blocks to rate center WOODSTOCK in area code 815, 3.6% 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. 11 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (5), ILLINOIS BELL TEL CO (4). The earliest assignment on record here is 2001-01-24 and the most recent 2002-04-02. 14 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 326, 507, 540, 779 – overlay codes cover the same geography, so a rate center is served by all of them.
