GUEYDAN prefixes in area code 337

NANPA records 6 assigned NXX blocks to rate center GUEYDAN in area code 337, 1.0% of the 599 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. 5 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - LA (2), TELEPORT COMMUNICATIONS AMERICA LA - LLC (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1). The earliest assignment on record here is 2002-05-03 and the most recent 2021-02-10. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
