DUNDEE prefixes in area code 224

NANPA records 7 assigned NXX blocks to rate center DUNDEE in area code 224, 1.2% of the 595 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. 7 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (1), FRACTEL, LLC (1), FIRST COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2002-09-19 and the most recent 2024-01-05. 7 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 507, 607, 734, 847 – overlay codes cover the same geography, so a rate center is served by all of them.
