A call or message from +246 you don't recognize
The country code shows which country's numbering plan a number is registered in. It doesn't show who is calling, and caller IDs can be spoofed, so a +246 number isn't proof that the person is in British Indian Ocean Territory.

- Never share verification codes, passwords or card details with someone who contacts you unprompted, whichever country the number appears to be from.
- If calls or messages keep coming, block the number and report it through your mobile carrier.
- Most calls from British Indian Ocean Territory are ordinary calls from family, friends, colleagues and businesses. If you are expecting one, save the number once the person has confirmed it.
