How to Identify Unknown Phone Numbers and Verify the People Behind Them

An unknown number on your smartphone screen doesn’t always mean it’s a spam call. It could be a courier, a potential employer, or even someone you’ve recently met. However, sometimes a scammer is behind such a call, who is trying to get money or personal details. You may find out who owns the number, but often with no need to call back. There are special services, search engines, and public social media profiles that may help. The main thing is to understand what info they provide and how reliable it is.

Identify the Owner of an Unknown Number

A simple search on Google or Bing is the easiest way to find unknown phone numbers with no need to install other apps. Enter the number in quotation marks, with the country code, and then try variations with spaces or hyphens. And if the contact is published on a company’s website, a public page, or in a business directory, the search engine may find a matching entry. Also, don’t forget to find out if the number is mentioned in other users’ complaints.

If the search yields no results, you may try to find Facebook account by phone number. This check can help you find a possible link between the number and a Facebook profile without logging into the social network or syncing your contacts. If there’s a match, the result may include a photo, username, and a link to the profile. Still, no results don’t necessarily mean the person doesn’t have a Facebook account. The number might have changed or be hidden from search results due to privacy settings. That’s why you must treat any profile you find as a lead for further investigation.

When Specialized Services Help

The reverse phone number lookup method allows you to search for info by phone number rather than by a person’s name. It may depend on the service and available records that results may include the likely owner, operator, geographic region, or a spam warning.

Meanwhile, phone number search tools don't guarantee that the info is up to date. Numbers are reassigned to new subscribers. Databases may still contain previous owners. That's why even finding a full name doesn't prove who exactly made the call.

Verify a Person's Identity With the Help of Social Media

If you want to find social media accounts by phone number, check public profiles on Facebook, Instagram, LinkedIn and other platforms. Search engines sometimes index profiles in which users have voluntarily posted their contact details.

Yet social media platforms restrict access to phone numbers. Even if a number is used for logging into an account, third-party users are not necessarily able to find the corresponding profile.

If a profile is found, then compare the name, occupation, workplace, and other publicly available details with the details that the person provided. Consider any inconsistencies. However, don't consider a photo or a match in names to be definitive proof of identity.

Verify the Authenticity of the Match

The task to verify phone number identity needs several independent confirmations. If a person claims to be a company employee, check their name on the official corporate website.

For business contacts, compare the email address with the organization’s official domain. If the person proposes a financial transaction, contact the company through a channel you already know.

Spot a Suspicious Call

Trying to identify unknown callers becomes critical when a stranger demands very fast action. Be attentive to requests to share a one-time code, password, bank details, or to transfer money urgently. Scammers can also spoof the number that appears on your screen. According to the Federal Trade Commission, Caller ID isn't reliable proof of the caller’s identity. Scammers might impersonate government agencies and well-known companies. That's why when you see a bank name or a familiar area code on the screen, it doesn't mean the call is legitimate.

Protect Your Personal Info

If a conversation seems suspicious, hang up and find the organization’s official contact details yourself.

• Don't click on links in unexpected text messages.
• Don't install remote access apps at the request of strangers.
• To verify a number, choose services with understandable terms of use and privacy policies. Do not grant access to your entire phone book unless necessary.

In the U.S., suspicious cases of fraud can be reported via ReportFraud.ftc.gov. If calls are repeated, use the number-blocking or spam-filtering features.

Bottom Line

Verifying an unknown number can help you figure out who you might be dealing with. But it’s no substitute for verifying a person’s identity. Search engines, public social media profiles, and specialized databases provide useful clues. However, they may contain outdated or incomplete info. When money or confidentiality is at stake, the most reliable option is to independently verify the caller through official channels and only then continue the call.
