ELKO prefixes in area code 775

NANPA records 15 assigned NXX blocks to rate center ELKO in area code 775, 2.5% of the 601 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 CITIZENS TELECOMM CO OF NV DBA FRONTIER COMM OF NV (5), NEW CINGULAR WIRELESS PCS, LLC (3), LEVEL 3 COMMUNICATIONS, LLC - NV (2). The earliest assignment on record here is 2003-03-03 and the most recent 2026-01-09. 10 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.
