THURMONT prefixes in area code 240
NANPA records 3 assigned NXX blocks to rate center THURMONT in area code 240, 0.4% of the 785 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. 2 holders hold those blocks, the largest being ONVOY, LLC - MD (2), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2004-11-01 and the most recent 2019-10-10. 3 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 codes 227, 301 – overlay codes cover the same geography, so a rate center is served by all of them.
