SANROSABCH prefixes in area code 850

NANPA records 6 assigned NXX blocks to rate center SANROSABCH in area code 850, 0.8% 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. (CENTRAL) (2), PAETEC ITEL, LLC (1), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2010-03-16 and the most recent 2020-06-16. 4 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 448 – overlay codes cover the same geography, so a rate center is served by all of them.
