Phone Number Scams Exposed – How to Spot & Avoid Them (2025)

How It Works

These guys use phone numbers as a hook to hook us and extract money or personal information from us. It sounds unpleasant, doesn't it? But if you know how they work, you can significantly increase your chances of not falling for their bait.

General Scams by Phone Number

It all comes down to using a phone call as an excuse to cheat.

Scenario	You receive a call from an unknown number. On the other end of the line, they tell you that you've won a prize, or that you're in trouble with the law, or that your credit card is blocked.
Goal	To make you make an immediate decision – to transfer money, provide personal information (for example, credit card number, password, etc.).
How it works	Scammers often use psychological techniques – they put pressure on fear, greed, or empathy. They try to create a situation in which you don't have time to think and start acting on emotions.
Example	"Hello! The bank's security service is calling you. Suspicious activity has been detected on your account. To prevent fraudulent transactions, you need to provide your card number and CVV code immediately."

Wrong Number Phone Call Scams

Scammers use an "erroneous" call to start a conversation and establish contact with a potential victim.

Home environment. An elderly woman is talking on the phone. She's worried. He holds a bank card in his hands and reads its data into his phone. The picture is crossed out with a red cross, you can't do that.

Scenario	You get a call. The stranger apologizes and says he got the wrong number. Then he tries to keep up the conversation, asks general questions, as if by chance he learns more about you.
Goal	To establish a trusting relationship so that you can use the information you receive for your own purposes. A scammer can make up a story about his difficult situation and ask for money in debt, or offer a profitable deal that turns out to be a deception.
How it works	Scammers count on your kindness and willingness to help. They use the tactic of "small steps", gradually dragging you into their deception.
Example	"Oh, sorry, I got the wrong number. And where are you from? We have such a bad connection here... and what do you do?"

Phone Number Spoofing Scams

Here, scammers disguise their real number by faking it for another one in order to increase the victim's trust.

Scenario	You receive a call from a number that seems familiar to you, such as your bank, hospital, or even someone you know.
Purpose	To impersonate a trusted person or organization in order to gain access to your personal data or money.
How it works	Scammers use special programs or services that allow you to substitute a phone number. This makes their call more believable and reduces the victim's vigilance.
Example	"Hello! Your bank is calling you. An unauthorized access attempt has been recorded on your account. To confirm your identity, please provide your login and password from online banking."

Signs of a Fraudulent Call

If you are promised something unrealistically cool, like winning the lottery, which you did not participate in, or a discount that looks too generous, then this is a reason to think.
Scammers often rush you to make a decision. "Just for today!", "There are only 5 minutes left!", "If you don't do it now, then...". This is done so that you don't have time to think and assess the situation.
If you get a call from an unfamiliar number, especially with a foreign country code, then this is a reason to be wary. Of course, this doesn't always mean fraud, but it's worth being careful.
Never share your personal information (card number, password, CVV code, etc.) on the phone if you are not sure who is calling. Even if they tell you that they are calling from a bank or other organization.
Pay attention to how the caller speaks. Does he have an accent? Does his story ring true? Are there any contradictions in his words? Sometimes small things can betray deception.
