WELSH prefixes in area code 337
NANPA records 4 assigned NXX blocks to rate center WELSH in area code 337, 0.7% 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. 4 holders hold those blocks, the largest being METROPCS, INC. (1), VOICESTREAM GSM I, LLC (1), BRIGHTSPEED OF LOUISIANA, LLC (1). The earliest assignment on record here is 2004-03-16 and the most recent 2004-03-19. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
