RAMEY prefixes in area code 787

NANPA records 3 assigned NXX blocks to rate center RAMEY 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. 1 holder holds those blocks, the largest being PUERTO RICO TEL. CO. (3). The same rate center name also appears in area codes 320, 939 – overlay codes cover the same geography, so a rate center is served by all of them.
