SELDEN prefixes in area code 516

NANPA records 25 assigned NXX blocks to rate center SELDEN in area code 516, 3.2% 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. 3 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (22), ZCALL.COM, INC. (2), SPOK, INC. (1). The earliest assignment on record here is 2001-09-05 and the most recent 2001-09-05. 2 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 631, 785, 934 – overlay codes cover the same geography, so a rate center is served by all of them.
