BRENTWOOD prefixes in area code 631
NANPA records 127 assigned NXX blocks to rate center BRENTWOOD in area code 631, 16.2% of the 782 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. 19 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NY (37), NEW CINGULAR WIRELESS PCS, LLC - DC (17), METROPCS, INC. (16). The earliest assignment on record here is 2001-01-16 and the most recent 2023-12-15. 90 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 516, 934 – overlay codes cover the same geography, so a rate center is served by all of them.
