RESERVE prefixes in area code 985

NANPA records 3 assigned NXX blocks to rate center RESERVE in area code 985, 0.7% of the 447 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. 2 holders hold those blocks, the largest being RESERVE TEL. CO. (2), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2008-03-12 and the most recent 2008-03-12. 1 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 406, 575 – overlay codes cover the same geography, so a rate center is served by all of them.
