SPENCER prefixes in area code 812

NANPA records 7 assigned NXX blocks to rate center SPENCER in area code 812, 0.9% of the 785 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. 6 holders hold those blocks, the largest being INDIANA BELL TEL CO INC (2), PAETEC ITEL, LLC (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (1). The earliest assignment on record here is 2001-11-01 and the most recent 2003-07-02. 6 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 234, 276, 304, 318 – overlay codes cover the same geography, so a rate center is served by all of them.
