SUNOL prefixes in area code 925
NANPA records 9 assigned NXX blocks to rate center SUNOL in area code 925, 1.4% of the 640 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 LEVEL 3 COMMUNICATIONS, LLC - CA (1), T-MOBILE USA, INC. (1), TELEPORT COMMUNICATIONS AMERICA, LLC - CA (1). 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
