HALF DAY prefixes in area code 847

NANPA records 16 assigned NXX blocks to rate center HALF DAY in area code 847, 2.0% 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. 6 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (8), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (4), METROPCS, INC. (1). The earliest assignment on record here is 2001-04-12 and the most recent 2009-07-14. 10 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 224 – overlay codes cover the same geography, so a rate center is served by all of them.
