List of the Best 10 Reverse Phone Lookup Tools

6 Key Features of Reverse Phone Lookup Tools and Software 

Reverse phone lookup tools come in an increasingly wide range of shapes and forms, these are the main features:

  • Pricing: Single-use phone lookup tools tend to be free. They might not be a viable solution for batch checks, though.
  • Integration: If you’re going to integrate a reverse phone lookup tool into your platform, make sure you do it in a way that makes sense for your business (APIs, manual queries, etc.).
  • Data privacy: Most reverse phone lookup tools only gather open-source data. However, be mindful of data protection laws such as GDPR.
  • Ability to scale: Can your tool grow along with your need to verify more phone numbers?
  • Data freshness: Where does the phone information come from? A stale database or fresh up-to-date sources?
  • Covered countries: Many free reverse phone lookup services are US-centric only. If you want to check international numbers, you’ll need to look elsewhere.

Spy Dialer

Great for Quick US Searches

Spy Dialer is a quick, easy-to-use reverse phone lookup service. It’s also completely free. You can search by name, address, or email.

Using Spy Dialer isn’t foolproof, though. You’ll find that non-US phone numbers won’t register in the system and that the results are mixed and not always reliable. However, if all you need is a quick free search to see who called you, it could do the trick.


  • Easy to use
  • Extra searches


  • Not scalable
  • US-only

Spy Dialer Pricing:

  • Spy Dialer is free of charge

Choose Spy Dialer if:

  • You want a barebones tool to look up US-based phone numbers

  • Extra searches: Spy Dialer can also separately look into addresses and names

Spy Dialer Cons:

  • Not scalable: You can only check one number at a time, and even then it might take up to five minutes 
  • US-only: We didn’t have much luck getting information on phone numbers from other countries


TransUnion’s OSINT Solution

TransUnion is a well-known player in the risk management world. The company acquired Iovation in 2018, an iGaming fraud prevention specialist, and has since deployed a number of solutions for businesses, including marketing and outreach. 

One of its latest products is TruLookup, which, as the name suggests, lets you enrich data to conduct quick manual investigations. It’s powered by the TLOxp platform, another acquisition from TransUnion.

TruLookup also lets you check for social media accounts, but it focuses mainly on public data sources including addresses, names, and phone numbers. The company also checks its own proprietary databases, which it claims include 10,000 data sources.


  • Draws from public and proprietary databases


  • Opaque pricing
  • Better suited for enterprise clients

TruLookup Pricing:

  • Unfortunately, you’ll have to contact TruLookup’s sales team to get an idea of how much each request costs

Choose TruLookup if:

  • You need to perform manual phone lookups and are already paying for TransUnion products, such as Truvalidate, truVision, or TruIQ.

TruLookup Pros:

  • From the renowned TransUnion company

While the company’s client list consists mainly of enterprise customers across financial services and large retailers, it is also possible to rely on its Device Recon module, which analyzes browser, mobile, desktop, and other technical user data to give you more information about who you are dealing with.

While it’s a more complex solution best adapted to batch screening, it’s a valid option for online merchants who rely on these data points to accept or decline transactions.


  • Benefits from PayPal’s datasets


  • Only focused on two key verticals
  • Better for enterprise clients
  • Non-transparent price

  • No pricing is available online

Ask an Expert

What Are Reverse Phone Lookup Tools?

A reverse phone lookup is a tool that takes a phone number and aggregates information associated with it to create a data-enriched profile. This information is often from open-source, or OSINT databases, such as social media, personal information registered with government bodies, messenger apps, and more. Some reverse phone lookup tools also cross-reference the provided phone number against proprietary databases of financial or transactional data.

Reverse phone lookup is a form of data enrichment. It’s a process designed to let you get extra information based on a single data point. Other examples include reverse email lookup and reverse social media lookup.

Data enrichment tools such as a reverse phone lookup solution are particularly useful when you’re trying to evaluate how risky a person is for your business. For instance, in fraud prevention, you can use that information to learn if the person appears suspicious or not.

Why Use Reverse Phone Lookup Tools?

Reverse phone lookup tools allow you to answer key questions to do with a phone number:

  • Who called me?
  • Who does the number belong to?
  • Is the phone number real and valid?
  • Should I trust the person who owns that phone number?

This is important both for individuals who want to know who they are dealing with and for companies that want to avoid doing business with the wrong people – especially fraudsters.

Advantages of Phone Numbers for Security

Phone numbers are harder to create than email addresses. Fraudsters don’t usually go through the trouble of getting new, real phone numbers for each of their fake personas or schemes.

And while apps like Hushed or Burner can generate new phone numbers, these have no digital presence – in other words, they won’t have any social, web, or messenger footprints. If there is no social data associated with the number, it is much more likely to belong to a fraudster rather than a legitimate user.

Historically, customers have been more reticent to share phone numbers than email addresses. This means there are fewer of them floating around on the dark web, and large lists of phone numbers have yet to appear in big data breaches. But this is good news: Any numbers that do get found in such leaks are very likely to belong to legitimate users.

Disadvantages of Phone Numbers for Security 

In the context of security at large, using phone numbers can also have some shortcomings. The first that comes to mind is two-factor authentication (2FA). 2FA with a phone number isn’t always as secure as one would hope. A growing number of white hat hackers have managed to bypass the security measure through phishing and other social engineering methods. 

Another issue arises with the increasing popularity of SIM-swapping attacks. This three-step process, also known as SIM splitting or SIM jacking, sees fraudsters acquire a phone number through hacks, phishing, or sheer luck.

They then call the mobile phone’s provider and claim to want to change their number to a new one. The new number, which is in the fraudster’s possession, will then receive all the messages used for mobile verification. This allows the criminal to access other accounts such as email, social media, or even mobile banking.

Frequently Asked Questions

Are reverse phone lookup tools legal?

Yes, as long as you collect data from open, public databases. It’s worth checking with your reverse phone lookup provider whether they abide by data security laws. SEON, for instance, is fully GDPR compliant.

Where does the phone number come from? How is this data sourced? 

Once you have a phone number, you can perform a reverse search to find information linked to it. The most common use is to find someone’s name. That data comes from the phone operator or caller ID service, which is open source, similar to a white or yellow pages search. 

Are there any hidden costs to using a phone lookup service?

A good phone lookup service will let you know its price ahead of time. Professional services tend to charge a monthly fee as part of a subscription. Beware of “free” phone lookup services where the query is free, but the results are hidden behind a paywall.

Will the person know I’m searching for their phone number?

No. A reverse phone search does not notify the phone owner that it’s being performed. 

What phone types does reverse phone lookup work for?

All kinds of phones. In fact, reverse phone lookups will tell you the type of phone it is. For instance, SEON’s Phone API results include whether the number is VoIP, whether it is disposable, the associated caller ID name (CNAM), the country of registration, and much more.
