Receiving calls from unknown numbers can be very annoying, especially when the calls are repetitive. While some may be telemarketers, many others are spammers looking to scam you.
Do you know that on average, a person receives about 7 spam calls in a month? This poses a threat to personal information and financial security. Usually, spam calls may be shown as No Caller ID number or as Spam Call if you have installed some detective program.
In this post, we will unveil the top 6 spam phone number lookup tools in 2025 for discovering information about the owners of spam and strange numbers.
How to Tell If the Number is Spam Number Before Answering It?
With spam calls becoming increasingly common, knowing how to tell if a phone number is fake before answering the call is important. Here are signs that a number might be spam–so you can stay a step ahead:
- 📱International Area Code that Looks Local: Spammers often tweak phone numbers to look like local area codes, making you think the call is from the neighborhood. For example: “+1 (555)-123-4567” might look local but the +1 shows that it’s an international area code.
- 👨⚖️Claims to be a Government Agent: Government agencies like the FBI and IRS don’t just call people. Usually, they make contact through their official mail. Know that the person calling and issuing threats regarding your taxes or legal issues is a fraudster.
- ⚠️Caller ID displays “Scam Likely” or “Spam Likely”: When your phone carrier or spam number checker tool names a suspicious number as “Scam Likely” or “Spam Likely”, it’s a strong indication that the number shouldn’t be trusted.
