LINWOOD prefixes in area code 989

NANPA records 3 assigned NXX blocks to rate center LINWOOD in area code 989, 0.4% of the 723 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. 3 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - MI (1), AT&T ENTERPRISES, LLC (1), MICHIGAN BELL TEL CO (1). The earliest assignment on record here is 2010-03-23 and the most recent 2010-12-07. 3 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 913 – overlay codes cover the same geography, so a rate center is served by all of them.
