ALBION prefixes in area code 517

NANPA records 11 assigned NXX blocks to rate center ALBION in area code 517, 1.8% of the 616 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. 10 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (2), WOW! INTERNET, CABLE AND PHONE (1), AT&T ENTERPRISES, LLC (1). The earliest assignment on record here is 2001-02-28 and the most recent 2012-04-03. 7 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 207, 208, 260, 402 – overlay codes cover the same geography, so a rate center is served by all of them.
