GOLDEN MDW prefixes in area code 985

NANPA records 3 assigned NXX blocks to rate center GOLDEN MDW in area code 985, 0.7% of the 447 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 ADVANCED TEL., INC. - LA (1), LEVEL 3 COMMUNICATIONS, LLC - LA (1), LAFOURCHE TEL. CO. (1). The earliest assignment on record here is 2013-04-08 and the most recent 2022-05-04. 1 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
