TRINIDAD prefixes in area code 719

NANPA records 11 assigned NXX blocks to rate center TRINIDAD in area code 719, 1.7% of the 665 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. 6 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - CO (3), ONVOY, LLC - CO (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CO (2). The earliest assignment on record here is 2002-02-06 and the most recent 2024-09-27. 10 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 369, 430, 707, 903 – overlay codes cover the same geography, so a rate center is served by all of them.
