FROMBERG prefixes in area code 406
NANPA records 3 assigned NXX blocks to rate center FROMBERG in area code 406, 0.4% of the 754 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 QWEST CORPORATION (1), TWILIO INTERNATIONAL, INC. (1), AT&T - LOCAL (1). The earliest assignment on record here is 2024-01-24 and the most recent 2024-01-24. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
