TOA ALTA prefixes in area code 939
NANPA records 3 assigned NXX blocks to rate center TOA ALTA in area code 939, 0.8% of the 359 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 LIBERTY MOBILE PUERTO RICO INC. (1), LIBERTY COMMUNICATIONS OF PUERTO RICO LLC (1), NEUTRAL TANDEM - PR (1). The earliest assignment on record here is 2015-12-28 and the most recent 2024-03-13. 3 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 787 – overlay codes cover the same geography, so a rate center is served by all of them.
