OXFORD prefixes in area code 513

NANPA records 13 assigned NXX blocks to rate center OXFORD in area code 513, 1.7% 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. 9 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (3), FRONTIER NORTH, INC. - OH (3), LEVEL 3 COMMUNICATIONS, LLC - OH (1). The earliest assignment on record here is 2001-08-30 and the most recent 2023-01-11. 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 207, 248, 283, 308 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
