TRABUCO prefixes in area code 949
NANPA records 32 assigned NXX blocks to rate center TRABUCO in area code 949, 4.3% of the 747 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. 15 holders hold those blocks, the largest being PACIFIC BELL (6), ONVOY, LLC - CA (5), COMCAST PHONE OF CALIFORNIA, LLC (4). The earliest assignment on record here is 2002-09-20 and the most recent 2025-12-18. 27 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
