NARANJITO prefixes in area code 939

NANPA records 6 assigned NXX blocks to rate center NARANJITO in area code 939, 1.7% 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 SUNCOM DBA T-MOBILE USA (4), METROPCS, INC. (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2017-12-21 and the most recent 2023-11-03. 6 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.
