HIGHLAND prefixes in area code 909

NANPA records 20 assigned NXX blocks to rate center HIGHLAND in area code 909, 2.5% 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. 10 holders hold those blocks, the largest being PACIFIC BELL (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (5), BANDWIDTH.COM CLEC, LLC - CA (3). The earliest assignment on record here is 2001-01-17 and the most recent 2020-08-06. 11 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 219, 353, 608, 618 – overlay codes cover the same geography, so a rate center is served by all of them.
