TOA BAJA prefixes in area code 787

NANPA records 3 assigned NXX blocks to rate center TOA BAJA in area code 787, 0.4% 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. 3 holders hold those blocks, the largest being WORLDNET TELECOMMUNICATIONS, INC. - PR (1), PUERTO RICO TELCO DBA CLARO PUERTO RICO (1), PUERTO RICO TEL. CO. (1). The earliest assignment on record here is 2007-01-19 and the most recent 2007-01-19. 2 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.
