CLIFFSIDE prefixes in area code 551
NANPA records 14 assigned NXX blocks to rate center CLIFFSIDE in area code 551, 4.7% of the 300 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. 9 holders hold those blocks, the largest being ONVOY, LLC - NJ (4), NEW CINGULAR WIRELESS PCS, LLC - DC (2), OMNIPOINT COMMUNICATIONS, INC. - NJ (2). The earliest assignment on record here is 2002-04-15 and the most recent 2023-09-21. 13 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 201 – overlay codes cover the same geography, so a rate center is served by all of them.
