SANTA CRUZ prefixes in area code 831
NANPA records 76 assigned NXX blocks to rate center SANTA CRUZ in area code 831, 18.7% of the 406 blocks assigned in the code.

The earliest assignment on record here is 2001-04-25 and the most recent 2026-07-24. 52 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
