PONCE prefixes in area code 787

NANPA records 24 assigned NXX blocks to rate center PONCE in area code 787, 3.1% 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. 6 holders hold those blocks, the largest being PUERTO RICO TEL. CO. (12), SUNCOM DBA T-MOBILE USA (5), METROPCS, INC. (2). The earliest assignment on record here is 2001-03-16 and the most recent 2007-07-16. 12 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 939 – overlay codes cover the same geography, so a rate center is served by all of them.
