GUAYNABO prefixes in area code 787
NANPA records 50 assigned NXX blocks to rate center GUAYNABO in area code 787, 6.4% 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 LIBERTY MOBILE PUERTO RICO INC. (42), PUERTO RICO TEL. CO. (7), OPTIVON TELECOMMUNICATIONS SERVICES, INC. - PR (1). The earliest assignment on record here is 2005-09-26 and the most recent 2005-09-26. 16 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.
