ENGADINE prefixes in area code 906

NANPA records 4 assigned NXX blocks to rate center ENGADINE in area code 906, 1.1% of the 360 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. 4 holders hold those blocks, the largest being INTERACTIVE SERVICES NETWORK, INC. (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (1), AT&T ENTERPRISES, LLC (1). The earliest assignment on record here is 2003-07-28 and the most recent 2023-08-29. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
