What is a VoIP number?
A VoIP (Voice over IP) number works over the internet — not traditional cell towers or copper landlines. Common services include Google Voice, Twilio, or TextNow. Many are free or disposable — that’s why they’re often used for scams or burner accounts.
Can I tell if a number is fake or disposable?
Yes — we flag numbers linked to shady providers, spam history, or inactive status. You’ll see a risk score, so you know what you’re dealing with.
What is HLR lookup?
HLR tells us if a mobile number is still active, ported, or unreachable. It’s how we help you avoid messaging dead numbers.
Can I see the owner’s name?
Yes — if available, we’ll show the caller name, region, and sometimes linked profiles.
