DEER PARK prefixes in area code 346

NANPA records 8 assigned NXX blocks to rate center DEER PARK in area code 346, 1.1% of the 752 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (3), FRACTEL, LLC (2), ONVOY, LLC - TX (1). The earliest assignment on record here is 2015-11-12 and the most recent 2024-10-07. 8 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 251, 281, 509, 631 – overlay codes cover the same geography, so a rate center is served by all of them.
