PRAGUE prefixes in area code 405

NANPA records 3 assigned NXX blocks to rate center PRAGUE in area code 405, 0.4% of the 783 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. 2 holders hold those blocks, the largest being VALOR TELECOM TX.LP-OK DBA WINDSTREAM COMM SW (2), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2006-12-14 and the most recent 2017-07-06. 3 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 code 402 – overlay codes cover the same geography, so a rate center is served by all of them.
