GLENBURNIE prefixes in area code 443
NANPA records 26 assigned NXX blocks to rate center GLENBURNIE in area code 443, 3.3% 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. 11 holders hold those blocks, the largest being OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (7), PAETEC ITEL, LLC (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MD (4). The earliest assignment on record here is 2001-04-20 and the most recent 2013-06-21. 25 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.
