MANGHAM prefixes in area code 318
NANPA records 4 assigned NXX blocks to rate center MANGHAM in area code 318, 0.5% of the 765 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. 3 holders hold those blocks, the largest being ONVOY, LLC - LA (2), BRIGHTSPEED OF LOUISIANA, LLC (1), NEW CINGULAR WIRELESS PCS, LLC - GA (1). The earliest assignment on record here is 2004-03-16 and the most recent 2022-11-22. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
