SELMA prefixes in area code 559

NANPA records 12 assigned NXX blocks to rate center SELMA in area code 559, 1.5% of the 785 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. 8 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (3), PACIFIC BELL (3), LEVEL 3 COMMUNICATIONS, LLC - CA (1). The earliest assignment on record here is 2001-12-26 and the most recent 2023-07-14. 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 334, 458, 483, 541 – overlay codes cover the same geography, so a rate center is served by all of them.

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.
