CLEVELAND prefixes in area code 423
NANPA records 33 assigned NXX blocks to rate center CLEVELAND in area code 423, 4.3% of the 764 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. 10 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (9), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TN (8), NEW CINGULAR WIRELESS PCS, LLC - GA (4). The earliest assignment on record here is 2002-10-11 and the most recent 2026-09-02. 25 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 216, 281, 315, 346 – overlay codes cover the same geography, so a rate center is served by all of them.
