GRAPEVINE prefixes in area code 817
NANPA records 36 assigned NXX blocks to rate center GRAPEVINE in area code 817, 4.6% of the 781 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. 11 holders hold those blocks, the largest being FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (14), ONVOY, LLC - TX (4), SOUTHWESTERN BELL TELEPHONE COMPANY - TX (3). The earliest assignment on record here is 2001-10-02 and the most recent 2023-12-20. 22 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 code 682 – overlay codes cover the same geography, so a rate center is served by all of them.
