BOERNE prefixes in area code 830

NANPA records 15 assigned NXX blocks to rate center BOERNE in area code 830, 3.0% of the 496 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. 10 holders hold those blocks, the largest being FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (3), WINDSTREAM COMMUNICATIONS TELECOM, L.P. - TX (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (2). The earliest assignment on record here is 2002-01-08 and the most recent 2026-09-21. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
