Who Is He or She, Really? Verifying a Contact
Updated 2026
A phone number is one of the few pieces of verifiable information in most online dating and marketplace conversations — here's how to use that without over-relying on it.
A common, reasonable use of reverse lookup: someone you met online has given you a phone number, and before meeting up or sending money, you want a basic sanity check. A lookup can confirm the number is a real, active line rather than a burner used exclusively for scams, and it can show whether other people have already flagged it for romance-scam or marketplace-scam patterns.
What this does and doesn't prove
A "clean" result — no spam reports, valid carrier — is not proof someone is trustworthy. It just means nobody has reported that specific number yet. Scammers rotate numbers constantly, and a first-time-used line will always come back clean regardless of intent.
Conversely, a flagged number is a strong reason for caution, but context matters — a legitimate small business number can occasionally get mistakenly reported.
The bigger red flags
- Refusing to video call after weeks of texting
- Any request for money, gift cards, or cryptocurrency before meeting in person
- A story that changes in small details over time
Treat a reverse phone lookup as one input among several, not a verdict. It's most useful for ruling out the obvious cases — a number tied to dozens of scam reports — rather than confirming someone is who they claim to be.
