CHINA prefixes in area code 409
NANPA records 4 assigned NXX blocks to rate center CHINA in area code 409, 0.9% of the 434 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. 4 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - TX (1), COMMIO, LLC (1), IP HORIZON LLC (1). The earliest assignment on record here is 2005-02-10 and the most recent 2025-02-04. 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 207 – overlay codes cover the same geography, so a rate center is served by all of them.
