TOWSON prefixes in area code 443
NANPA records 33 assigned NXX blocks to rate center TOWSON in area code 443, 4.2% 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. 10 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MD (9), PAETEC ITEL, LLC (5), NEW CINGULAR WIRELESS PCS, LLC - DC (5). The earliest assignment on record here is 2001-05-10 and the most recent 2014-06-13. 32 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 410, 667 – overlay codes cover the same geography, so a rate center is served by all of them.
