STFRNCISVL prefixes in area code 225

NANPA records 7 assigned NXX blocks to rate center STFRNCISVL in area code 225, 1.4% of the 501 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 NEW CINGULAR WIRELESS PCS, LLC - GA (2), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2021-10-20 and the most recent 2021-10-20. 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 code 618 – overlay codes cover the same geography, so a rate center is served by all of them.
