KEYS prefixes in area code 305
NANPA records 138 assigned NXX blocks to rate center KEYS in area code 305, 17.6% of the 785 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. 21 holders hold those blocks, the largest being METROPCS, INC. (20), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (19), OMNIPOINT MIAMI E LICENSE, LLC (15). The earliest assignment on record here is 2001-04-27 and the most recent 2024-05-21. 120 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 645, 786 – overlay codes cover the same geography, so a rate center is served by all of them.
