AGUADILLA prefixes in area code 787

NANPA records 12 assigned NXX blocks to rate center AGUADILLA in area code 787, 1.5% 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. 7 holders hold those blocks, the largest being SUNCOM DBA T-MOBILE USA (5), PUERTO RICO TEL. CO. (2), METROPCS, INC. (1). The earliest assignment on record here is 2001-08-07 and the most recent 2022-02-14. 8 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.
