History of the 346 area code
- 346 is the fourth code in the Houston overlay. The Public Utility Commission of Texas announced it in 2013 and it went into service on July 1, 2014.
- Because it is an overlay, 346 numbers are handed out across the whole Houston area rather than to one part of it.
- 621 was added as a fifth Houston overlay in 2025.
Is a call from the 346 area code a scam?
Not because of the area code. 346 is an ordinary Texas area code used by homes, businesses and cellphones. Scammers can fake any caller ID, including 346 numbers, so judge the call by what the caller asks for, not by the number.
- Spoofing. Robocallers often fake a local-looking number. A 346 caller ID does not prove the call came from Texas.
- Look-alike codes. Some three-digit codes that look domestic, such as 876 (Jamaica) and 809 (Dominican Republic), are international. Calling back a missed call from one can cost money. 346 is not one of them.
- What to do. Don't share codes, passwords or payment details with an unexpected caller. Report scam calls at reportfraud.ftc.gov and register your number at donotcall.gov.
Get a 346 number for your AI agent
Yes, if one is available. Every KaiCalls plan, from $10/mo, includes one phone number, and you can choose or swap its area code. From inside your agent, CallMCP's search_available_numbers tool checks live carrier inventory with area_code "346", and an extra line ($15/mo) is bought through a buy_number request that the account owner approves. Inventory changes, so a search for 346 can come back empty.

"name": "search_available_numbers",
"arguments": { "area_code": "346", "country": "US", "limit": 5 }
}The purchase step, buy_number, only files a request. A human on the account approves it before anything is bought, and then attach_number routes the number to your agent. The phone-number guide walks through every call. Owning a 346 number does not give your agent permission to call people there; read outbound call safety and consent first.
