GRANTS prefixes in area code 505

NANPA records 14 assigned NXX blocks to rate center GRANTS in area code 505, 2.0% of the 685 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 - NM (3), QWEST CORPORATION (3), ONVOY, LLC - NM (2). The earliest assignment on record here is 2007-08-22 and the most recent 2022-03-10. 14 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.

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.
