ANSONIDRBY prefixes in area code 203
NANPA records 17 assigned NXX blocks to rate center ANSONIDRBY in area code 203, 2.2% of the 784 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. 7 holders hold those blocks, the largest being SOUTHERN NEW ENGLAND TELCO DBA FRONTIER COMM OF CT (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CT (4), OMNIPOINT COMMUNICATIONS, INC. - CT (3). The earliest assignment on record here is 2001-05-01 and the most recent 2012-01-18. 12 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 475 – overlay codes cover the same geography, so a rate center is served by all of them.
