CAROLINA prefixes in area code 787
NANPA records 18 assigned NXX blocks to rate center CAROLINA in area code 787, 2.3% of the 777 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 PUERTO RICO TEL. CO. (10), LIBERTY MOBILE PUERTO RICO INC. (3), SUNCOM DBA T-MOBILE USA (3). The earliest assignment on record here is 2004-05-05 and the most recent 2022-05-13. 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 codes 401, 939 – overlay codes cover the same geography, so a rate center is served by all of them.
