LONG BEACH prefixes in area code 910

NANPA records 6 assigned NXX blocks to rate center LONG BEACH in area code 910, 0.8% 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. 5 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (2), BANDWIDTH.COM CLEC, LLC - NC (1), UNITED STATES CELLULAR - NC (1). The earliest assignment on record here is 2003-11-06 and the most recent 2020-08-28. 4 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 360, 472, 562 – overlay codes cover the same geography, so a rate center is served by all of them.
