HOLLY prefixes in area code 248

NANPA records 22 assigned NXX blocks to rate center HOLLY in area code 248, 2.8% of the 784 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 METROPCS, INC. (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (4), LEVEL 3 COMMUNICATIONS, LLC - MI (3). The earliest assignment on record here is 2001-10-01 and the most recent 2016-06-30. 15 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 719, 947 – overlay codes cover the same geography, so a rate center is served by all of them.
