FREEPORT prefixes in area code 979

NANPA records 20 assigned NXX blocks to rate center FREEPORT in area code 979, 4.8% of the 413 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. 8 holders hold those blocks, the largest being SOUTHWESTERN BELL (10), AERIAL COMMUNICATIONS, INC. (3), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2001-10-23 and the most recent 2018-08-30. 14 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 207, 320, 616, 620 – overlay codes cover the same geography, so a rate center is served by all of them.
