Phone Lookup

Phone numbers are increasingly becoming a form of online ID. You can use yours to sign up for social media sites and to confirm your identity via MFA (multi-factor authentication). They’re also a fantastic way to learn more about an online user thanks to the data enrichment process called a phone lookup.

For instance, a phone lookup will show if you’re dealing with someone in the right country with a legitimate SIM, or a suspicious individual who is wasting your time with junk or falsified data.

SEON checks phone numbers against more than 50 digital and social media sites to deliver a wealth of information such as the person’s avatar, bio and profile info. It’s a key tool to accept good/legitimate users without interrupting their experience – while blocking out junk leads and obvious fraudsters who may damage your business.


What can SEON’s reverse phone lookup do?

A reverse phone lookup allows you to gather extra user information based on a phone number only. You can check if it’s valid, whether it’s linked to social media accounts, and if it’s from a disposable number, among other things.

Is SEON’s reverse phone lookup tool legal to use?

Yes, reverse phone lookup tools are completely legal. SEON’s reverse phone lookup only aggregates open-source data and meets all GDPR requirements.
