AUBURN HTS prefixes in area code 248

NANPA records 20 assigned NXX blocks to rate center AUBURN HTS in area code 248, 2.6% 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. 7 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (6), LEVEL 3 COMMUNICATIONS, LLC - MI (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (4). The earliest assignment on record here is 2001-12-28 and the most recent 2002-03-12. 13 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 947 – overlay codes cover the same geography, so a rate center is served by all of them.
