SIDONIA prefixes in area code 731
NANPA records 3 assigned NXX blocks to rate center SIDONIA in area code 731, 0.8% of the 395 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. 3 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - TN (1), ONVOY SPECTRUM, LLC (1), CITIZENS COMM CO TN DBA FRONTIER COMM OF TN, LLC (1). The earliest assignment on record here is 2017-11-30 and the most recent 2023-05-10. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
