TRUJILLOAL prefixes in area code 787

NANPA records 61 assigned NXX blocks to rate center TRUJILLOAL in area code 787, 7.9% 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. 4 holders hold those blocks, the largest being PUERTO RICO TELCO DBA CLARO PUERTO RICO (50), PUERTO RICO TEL. CO. (7), LIBERTY MOBILE PUERTO RICO INC. (3). The earliest assignment on record here is 2001-04-20 and the most recent 2001-04-20. 5 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.
