An unfamiliar phone number appears on your screen. Is it a legitimate business, a telemarketer, or a scammer? One missed call is not enough to know, but a few simple checks can help you decide what to do next.
Start with a number search
Search the full number online, including the area code. A phone-number lookup site such as CallCheck.ca may show whether other people have reported the number and what kind of call they received. Treat reports as clues, not proof: numbers can be spoofed, reassigned, or reported by mistake.
Look for patterns, not just one clue
Be cautious if the caller repeatedly hangs up, leaves no useful message, uses a recorded voice, or immediately asks for money or personal information. A local-looking number does not guarantee that the caller is nearby—or genuine.
Do not call back automatically
If the call claims to be from a bank, government office, delivery company, or utility, find the organization’s official contact information independently. Use the number on your card, statement, or official website rather than a number supplied by the caller.
What if you answer?
You can ask who is calling and why, but do not confirm sensitive information. Never share passwords, one-time security codes, or banking details with an unexpected caller. If the conversation feels pressuring, end it.
Help others identify unwanted calls
If you believe a call was spam, record the date, displayed number, and general call type. Avoid posting private information about individuals. You can use CallCheck.ca to look for reports or contribute a factual report if the site offers that feature.
The safest approach is to verify independently. A number’s reputation can help you decide what to check, but it should never replace careful verification.
