RIVERDALE prefixes in area code 708

NANPA records 10 assigned NXX blocks to rate center RIVERDALE in area code 708, 1.3% of the 784 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 (3), TELEPORT COMMUNICATIONS AMERICA, LLC - IL (2), LEVEL 3 COMMUNICATIONS, LLC - IL (1). The earliest assignment on record here is 2001-04-12 and the most recent 2024-02-08. 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 308, 464, 559, 620 – overlay codes cover the same geography, so a rate center is served by all of them.
