SANTURCE prefixes in area code 939

NANPA records 39 assigned NXX blocks to rate center SANTURCE in area code 939, 10.9% 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. 5 holders hold those blocks, the largest being LIBERTY MOBILE PUERTO RICO INC. (19), SUNCOM DBA T-MOBILE USA (16), LUMEN TECHNOLOGIES PUERTO RICO, LLC (2). The earliest assignment on record here is 2001-08-06 and the most recent 2024-07-10. 31 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.
