About the 346 region
346 covers Houston in Texas, including Harris, Brazoria, Chambers, Fort Bend and Galveston. The code has been in service since 2014.
346 itself is an overlay: it shares its territory with 713 and 281 and was introduced when those codes ran low on new number combinations. New lines may receive either code, calls between them are local, and 10-digit dialing is required across the region.

Who called me from 346?

- Avoid calling back unknown one-ring numbers — some premium-rate scams rely on curiosity callbacks.
- Never share verification codes, payment details, or remote access during an unsolicited call, even if the caller claims to be your bank or a government agency.
- When a 346 call pressures you to act immediately, hang up and contact the organization directly through its official number.
