HOLLEYNVRR prefixes in area code 850

NANPA records 9 assigned NXX blocks to rate center HOLLEYNVRR in area code 850, 1.1% of the 786 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. 5 holders hold those blocks, the largest being ONVOY, LLC - FL (3), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (3), LEVEL 3 COMMUNICATIONS, LLC - FL (1). The earliest assignment on record here is 2003-06-04 and the most recent 2021-05-12. 7 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 code 448 – overlay codes cover the same geography, so a rate center is served by all of them.
