ST CLOUD prefixes in area code 407

NANPA records 9 assigned NXX blocks to rate center ST CLOUD in area code 407, 1.1% of the 786 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 CENTURYLINK OF FLORIDA, INC. (UNITED) (4), METROPCS NETWORKS, LLC (2), TELEPORT COMMUNICATIONS AMERICA, LLC - FL (1). 7 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 codes 320, 321, 689, 920 – overlay codes cover the same geography, so a rate center is served by all of them.
