NANPA records 21 assigned NXX blocks to rate center BAYSTLOUIS in area code 228, 7.6% of the 275 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. 9 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (7), CELLULAR SOUTH, INC. (2), LEVEL 3 COMMUNICATIONS, LLC - MS (2). The earliest assignment on record here is 2001-05-24 and the most recent 2012-08-21. 15 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
