WESTFIELD prefixes in area code 281
NANPA records 14 assigned NXX blocks to rate center WESTFIELD in area code 281, 1.8% 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. 5 holders hold those blocks, the largest being SOUTHWESTERN BELL (8), LEVEL 3 COMMUNICATIONS, LLC - TX (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - TX (2). The earliest assignment on record here is 2004-01-20 and the most recent 2004-01-20. 9 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 217, 317, 336, 346 – overlay codes cover the same geography, so a rate center is served by all of them.
