DENHAM SPG prefixes in area code 225
NANPA records 21 assigned NXX blocks to rate center DENHAM SPG in area code 225, 4.2% of the 501 blocks assigned in the code.

The earliest assignment on record here is 2001-08-02 and the most recent 2026-09-09. 17 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
