Who called me from a 343 number?
343 is a Canadian area code covering eastern Ontario, including Ottawa, Kingston and Cornwall. It is used for both landline and mobile numbers, and numbers keep their area code when people move or change carriers. Caller ID showing a 343 number can also be spoofed, so check the reports below before you trust the caller.

Before you call a 343 number back
- Caller ID is supplied by the calling network, not verified by your phone — a familiar-looking number is not proof of who is on the line.
- One ring with no voicemail is rarely worth returning. Read our guide on missed calls first.
- If the caller wants money, a code or remote access, hang up and dial the organisation on a number you found yourself. See bank impersonation calls.
