JOHNSON CY prefixes in area code 830
NANPA records 5 assigned NXX blocks to rate center JOHNSON CY in area code 830, 1.0% 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. 4 holders hold those blocks, the largest being FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (2), NEW CINGULAR WIRELESS PCS, LLC - IL (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (1). The earliest assignment on record here is 2001-06-20 and the most recent 2002-03-28. 5 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 423 – overlay codes cover the same geography, so a rate center is served by all of them.
