LINN prefixes in area code 573

NANPA records 4 assigned NXX blocks to rate center LINN in area code 573, 0.5% of the 786 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 LEVEL 3 COMMUNICATIONS, LLC - MO (1), VONAGE AMERICA LLC (1), IP HORIZON LLC (1). The earliest assignment on record here is 2004-04-06 and the most recent 2020-12-02. 4 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 235, 785 – overlay codes cover the same geography, so a rate center is served by all of them.
