Sometimes age verification feels over-the-top. You might be asked for your ID number or a selfie. That's normal for online purchases, especially for age-restricted products.

But there's a line. Legitimate services never ask for your Social Security number. If a seller asks for that, you're not dealing with a normal age check—you're dealing with a potential scam. Close the tab.

Also, know that age verification services don't store your ID photo unless you give explicit consent. Most just confirm your age and move on.
