CALDWELL prefixes in area code 986

NANPA records 5 assigned NXX blocks to rate center CALDWELL in area code 986, 2.6% of the 189 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. 4 holders hold those blocks, the largest being ONVOY, LLC - ID (2), TELEPORT COMMUNICATIONS AMERICA, LLC - ID (1), BANDWIDTH.COM CLEC, LLC - ID (1). The earliest assignment on record here is 2019-03-08 and the most recent 2026-10-02. 5 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 201, 208, 620, 740 – overlay codes cover the same geography, so a rate center is served by all of them.
