BROWNSVL prefixes in area code 731

NANPA records 13 assigned NXX blocks to rate center BROWNSVL in area code 731, 3.3% of the 395 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. 10 holders hold those blocks, the largest being ONVOY, LLC - TN (2), NEW CINGULAR WIRELESS PCS, LLC - GA (2), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2). The earliest assignment on record here is 2002-07-18 and the most recent 2024-04-10. 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 270, 364, 458, 507 – overlay codes cover the same geography, so a rate center is served by all of them.
