PALM SPG prefixes in area code 442

NANPA records 27 assigned NXX blocks to rate center PALM SPG in area code 442, 7.6% of the 356 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. 15 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (11), NUSO, LLC (2), ONVOY, LLC - CA (2). The earliest assignment on record here is 2014-04-11 and the most recent 2026-09-09. 27 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 760 – overlay codes cover the same geography, so a rate center is served by all of them.
