CISCO prefixes in area code 254
NANPA records 5 assigned NXX blocks to rate center CISCO in area code 254, 0.7% of the 672 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 SHELCOMM (1), SOUTHWESTERN BELL (1), CSC VOICE, LLC (1). The earliest assignment on record here is 2012-11-14 and the most recent 2024-02-05. 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 217 – overlay codes cover the same geography, so a rate center is served by all of them.
