Received a call or message from +255?
A call or text from +255 (or 00255) originates from Tanzania.
If you don't know anyone in Tanzania, be cautious. Common patterns with unfamiliar international numbers:
- One-ring scams (Wangiri): The caller rings once and hangs up, hoping you'll call back a premium-rate number. Don't return calls to numbers you don't recognize.
- SMS phishing: Messages claiming to be from banks, delivery services, or government agencies. Legitimate organizations won't contact you from a +255 number unless you have an account in Tanzania.
- Spoofed numbers: The caller ID can be faked. A call showing +255 may not actually originate from Tanzania.
If you do know someone in Tanzania and want to call them back, see the dialing instructions below.
