E CLARIDON prefixes in area code 440

NANPA records 5 assigned NXX blocks to rate center E CLARIDON in area code 440, 0.7% of the 757 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 T-MOBILE USA, INC. (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2), WINDSTREAM WESTERN RESERVE, INC. (1). The earliest assignment on record here is 2002-03-20 and the most recent 2024-03-07. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
