CATONSVL prefixes in area code 410
NANPA records 35 assigned NXX blocks to rate center CATONSVL in area code 410, 4.5% 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (26), VERIZON MARYLAND, INC. (6), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MD (1). 10 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 443, 667 – overlay codes cover the same geography, so a rate center is served by all of them.
