How to Find Someone’s Phone Number (Absolutely for Free)

Finding a person’s phone number can be crucial in sales, recruiting, or even simply reconnecting with an old friend. Unfortunately, it may feel like looking for a needle in a digital haystack.

In the business world, even today the majority of C-suite executives list cold calls as their preferred contact method, but it’s still your responsibility to find the right number. 

No matter the situation, most of us have been there—staring at a screen, thinking, “There’s got to be a way to find this number without paying some sketchy website.”

We bring you good news: there is a way! Finding a phone number for completely free is totally doable if you know where to look. You just need a little creativity, the right tools, and a few tricks up your sleeve.

We’ve already covered how to find anyone’s email for free, but now it’s time to focus on the second main contact information: phone numbers. 

By the end of this article, you’ll have a comprehensive set of strategies covering all practical free methods to find phone numbers, from public directories and social media to reverse-lookup tools. 

How to find someone’s phone number for free 

There are so many reasons why one might need to find someone’s phone number, both for personal and business reasons. It might be for sales outreach, hiring & recruiting, reconnecting with contacts, or verifying one’s identity, to name a few. 

As an example, at Reply.io our main set of features revolves around AI-powered sales outreach, but we also offer users a native contact database with over 1 billion live contacts, including their emails, company info, and more, to help sales teams reach their desired contacts. 

Each reason for finding someone’s phone number will have its own set of most effective strategies—business contacts often appear in corporate channels while personal contacts may surface in social media and local directories. 

The main free sources of phone numbers that you can leverage include: 

1. Search directories → think of these digital yellow pages, including public phone directories and people-search websites available to everyone on the web; 
2. Social media → platforms like LinkedIn, Facebook, Instagram, Twitter, etc. can often carry personal contact information like emails and phone numbers;
3. Lead databases → B2B data finders like the one offered by Reply.io often have free trials or limited free search credits; 
4. People-search engines → dedicated sites that aggregate public records to store contact information (may require sign-up or payment for full results); 
5. Company/university sites → many organizations including companies and educational establishments list employee / student contact info on official websites. 

Now, let’s take a closer look at each of these methods (and more) along with real-life examples, tool descriptions, and extra tips for best results.

Phone lookup tactic #1: Search directories 

Back in the day, we had yellow pages and phonebooks. In today’s digital world, we have online search directories, though it’s worth noting that most of them are US-based. 

They let you search by name and location, or do a reverse lookup instead by entering a phone number to find its owner (we’ve got an entire section on that later). These free directories often compile data from public databases, old phone books, property records, and any other available online records. Let’s take a closer look at the 3 most popular search directories.

Whitepages (whitepages.com) 

This is the original, central online phone directory for the US. You can simply enter a name and city/state to find phone numbers and addresses. Whitepages is essentially a digitized phonebook and even offers reverse lookup (enter a number to get a name). 

It also has premium features like “background checks”, but those require payment. If you’re simply looking for someone’s phone number—the basic search is completely free, but keep in mind that information may be outdated. 

TruePeopleSearch (truepeoplesearch.com) 

Next up we have TruePeopleSearch—a free people search engine that allows searches by name, address, or phone number. It claims access to “billions of public records” for reconnecting with people, also primarily in the US.

 You simply enter a name (and city/zip) to get phone numbers, addresses, and more. 

The site is 100% free, though it partners with BeenVerified for additional paid data that comes at an extra cost (irrelevant if all you’re after is a phone number). 

AnyWho (anywho.com) 

Last on our list is AnyWho, another free US online search directory that allows users to simply enter their name and location (if available, for better results). This website focuses primarily on landline numbers though there are tons of mobile numbers too. 

It’s simple and free, though data is limited as it pulls information from old phone books, but for basic queries, it often suffices.

Extra tips:

• Combine names with middle initials or nicknames if a full name search yields too many results.
• Use quotes in Google with site filters, e.g. [site:whitepages.com “Jane A. Doe” Seattle] to directly target the whitepages site.
• Try variations of locations (city vs. county, zip codes) to cover different listing formats.
• If a person recently moved, older addresses may still appear in these databases, so potentially check historical info as well.

Phone lookup tactic #2: Social media 

Given that virtually every single person is on social media, it should come as no surprise that it is one of the biggest sources of contact information. Many people use their phone numbers to register for these platforms, while many professionals link their phone numbers and/or emails on their profiles for easy communication. 

While social networks are privacy-focused, they can still yield contact info if the person made it public or if their profile hints at it. Also, there are specialized tools (most often Chrome extensions) that can extract contact details, including phone numbers, from public profiles. 

Below are platform-by-platform strategies:

LinkedIn

If you’re looking for someone’s contact number for business purposes, LinkedIn is your best bet, especially for B2B activities. LinkedIn profiles don’t normally display phone numbers publicly, but users can add them to their contact info which is visible to accepted connections.

Here are the ways to leverage LinkedIn to find someone by phone number free of charge: 

• Manual check → if you’re connected to someone on LinkedIn, you can visit their profile, and click “Contact info” (below their photo). Sometimes, a phone number is listed if they choose to share it with connections. If you aren’t on their list of connections, you can try sending a connection request with a personal note, and once connected, you may notice their shared contact info.
• LinkedIn scraping tools → there are numerous free Chrome extensions that can automatically find contact details from LinkedIn profiles. 

For example, Findy is a neat extension that scrapes LinkedIn profiles as you view them, extracting email addresses and phone numbers (when available). It runs in the background, compiling data without any coding or set-up needed.

• Sales Navigator or third-party tools → if you have access to paid tools like LinkedIn’s Sales Navigator or third-party tools like SignalHire, they may offer contact info in bulk or enable API searches for numbers. While we’re focusing on free methods, we felt it was worth mentioning.

Facebook

People sometimes list phone numbers on their Facebook profiles, though it’s pretty rare (and hidden by default). In any case, here’s some food for thought:

• About/contact info → Visit the person’s Facebook profile and click “About”, and then “Contact and basic info.” If they’ve added a phone number and made it visible (public or friends-only), it will appear there. Keep in mind this is uncommon: users choose whether to show their phone, and most, for obvious reasons, keep it hidden.
• Profile clues → even if the phone isn’t listed, you can use the “About” section to find their email, workplace, or links to personal websites which may contain contact details. Similarly, they could have their LinkedIn profiles in their Facebook bio, in which case you could leverage a LinkedIn scraper. 
• Search by phone → Facebook’s mobile app has a “Find People” feature where you can add a phone number to see if it matches an account. (It works only if you already have the number saved). Facebook then suggests profiles linking to that number.

Instagram

If it’s a business account, Instagram profiles have a special “Contact” button which may show the person’s phone and/or email. Alternatively, you could try: 

• Phone sync trick → Instagram doesn’t let you search by number. However, if you add someone’s phone number to your phone contacts and then enable Instagram’s “Contacts” sync (Discover People), Instagram will suggest profiles matching saved numbers. This is a common workaround—save the target’s number, let Instagram scan your contacts, and see if it finds a linked account. After checking, you can remove the contact from your phone.
• Google “Instagram + name” → sometimes non-business accounts don’t have contact info, but a Google search of “Name Instagram” might reveal their username, then manual messages can be used to ask or find clues.

Pro tip: for all social networks, combining info can help. For instance, you might leverage email finders on an Instagram profile, then use that email to do a reverse lookup on LinkedIn, and then leverage a LinkedIn scraper like Findy to uncover their phone number. Finally, you can use the person’s full name and location (from LinkedIn/Facebook) in Google to uncover news articles, conference speaker pages, or blogs that may potentially list contact info.

Phone lookup tactic #3: Lead databases (B2B focus)

Specialized business lead databases often have the most up-to-date emails and phone numbers, so if you’re looking for business contacts—this is probably the prime method. While many are paid, the majority offer limited free access or trials. 

The key is they compile business contact info from multiple sources and let you search companies or people directly through the platform. At Reply.io, we have our own lead database with over 1 billion contacts, but it’s worth noting that there are other examples out there like lemlist and alternatives. 

Reply.io → the Reply.io sales automation suite provides a B2B contact database with over 1 billion global contacts, including names, email addresses, company information, and more. 

Businesses can take it a step further and leverage Reply.io to enrich the profiles of potential buyers or partners with additional data, including intent signals. Moreover, they can then launch AI-powered outreach across multiple channels, including phone calls, to connect with those people. 

Why use databases → the main selling point of lead databases is that instead of manually searching individuals one by one, they let you filter by industry, geography, role, etc., and produce lists of all relevant contacts. These are especially useful if you need bulk outreach or are building a list of prospects. After finding names, the enrichment feature can append missing phones or emails.

Phone lookup tactic #4: Company/university websites

Official websites of organizations (companies, universities, associations) often list employee/student/member contact info publicly. For academics or corporate staff, check department or team pages, university directories, or official phonebooks. 

Even if a direct page isn’t obvious, you can use Google with advanced operators to probe these sites:

1. Company staff/contact pages → visit the target’s organization site. Look for the “About Us,” “Our Team,” “Contact,” or “Meet the Team” sections. Many organizations list key staff/member names along with their direct phone or extensions (especially executives or salespeople) on these pages. 
2. Search operators → if browsing the site manually is hard, use Google’s site: filter. For example, you could type in [site:company.com “John Smith” phone] or [site:university.edu John Doe contact]. This way, Google will do the work for you and scan those websites for any information related to the contact you’re looking for. 
3. Use alumni databases → Some associations (e.g. professional societies, alumni networks) allow member lookup. If you and the person share an organization, search their member directory. For example, LinkedIn’s alumni tool (found on University pages) shows connections, and sometimes university alumni directories (LinkedIn groups, local chapters) include contact info for members.
4. WHOIS domain lookup → if the person has a personal or business website, perform a WHOIS lookup on their domain. Occasionally, domain registration details include a registrant’s phone number or email (though many use privacy services nowadays). Still, it can be a last resort.

In summary, official websites can be gold mines for business contact info. Combined with Google, you can often find someone’s phone numbers that social media or directories don’t have. Always double-check that the contact is up-to-date, as organization websites sometimes lag behind recent hires or moves.

Phone lookup tactic #5: People-search engines

People-search engines are like online directories (that we covered above) but on steroids. They offer in-depth data aggregated across multiple sources, including public records, social networks, data brokers, web content, web mentions, and at times even criminal records. 

As you can imagine, these come at a cost, either a subscription or a per-search fee. So while we won’t go into detail here, here are the top-rated people-search engines, should you decide to go for the paid option: Pipl, BeenVerified, and Intellius. 

These websites may be worth trying if all other methods fail. 

Reverse number lookup 

Now that we’ve covered how to find someone’s phone number, let’s talk about the opposite scenario. 

Sometimes, you may have a phone number, and you’re trying to figure out who it belongs to. In that case, there are several reverse lookup tactics you can turn to. 

This is especially useful in situations when you get a call from an unfamiliar number and wish to determine who the caller is. 

• Google/Bing search → the simplest step is to just Google the number in quotes. Sometimes people post their number on forums, social media, or classified ads, and a quick search can reveal a name or context. Try a couple of variations—search without the country code, with dashes/spaces, etc. If your contact ever left their phone number anywhere on the web—this search will find it. You can also use other search engines like DuckDuckGo or StartPage, as they may index different pages or respect privacy filters differently.
• Social media → we discussed how you can use social media to find someone by phone number free of charge, but the same goes for the other way around. You could search for the number on Facebook or Instagram, and there’s a chance that the user will show up (only if they publicly added their number). 

Also, on WhatsApp or Telegram, if you add the number to your contacts and then check the app, it may show the user’s profile name and picture (if they use the default privacy settings). 

• Dedicated reverse lookup tools → last but not least, there are free and paid services specifically designed for reverse phone lookup. The most popular examples include Spokeo, Truecaller, Whitepages, AnyWho, and IPQS. 

Overall, there are multiple strategies on how to find someone by their phone number, and a combination of the above-mentioned should get the job done. 

For any given number, try at least a Google search, Truecaller, and Whitepages. If it’s a mobile number not publicly listed, you may only find limited info, so you could also use the context (caller ID region, any voicemail, etc.) for clues.

Extra free phone lookup hacks

Even though we’ve covered the main tactics for finding someone’s phone number for free, here are a few extra points to keep in mind to help you on your mission: 

• Use alternative search engines → Google isn’t the only player in the game. DuckDuckGo or StartPage might index different sites and could therefore produce different search results.  
• Mutual contacts & referrals → if you’re finding it challenging to find someone’s number, you could try connecting with mutual friends or colleagues and ask them for contact information. Sometimes the simplest way is simply to ask someone who already knows the person.
• Event and conference lists → if the person speaks at or attends industry events, conference websites sometimes publish attendee lists or speaker bios (with contact info). If you know an event they might attend or present, search the event site or LinkedIn event posts.
• Email signatures (for networked users) → if the person whose number you’re looking for has exchanged emails with you or your team in the past, try double-checking their email signature. Sometimes professionals include their personal phone numbers. 

As a final disclaimer—always be mindful! These hacks vary in legality and privacy compliance depending on where you reside, so always make sure to double-check what you’re allowed to do and what you aren’t. With free AI models like ChatGPT, you can easily find the answers. 

Whenever working with other people’s data, always remain ethical, for example, not harassing them or misusing their data. Respect privacy laws and do-not-call lists when contacting numbers you find.

Bottom line 

In summary, finding someone’s phone number for free may be quite challenging, but not impossible. There are numerous techniques to uncover someone’s phone number and to discover the name of the person with their phone number, depending on your situation. 

Online directories, social media platforms, dedicated tools, and Google searches are among the most common free techniques, and then there are also paid tools for those interested. 

Generally, business professionals like sales reps, recruiters, and even C-suite executives are much easier to find because their numbers are tied to organizations, and often to their LinkedIn profiles. In fact, the more senior or public-facing they are, the likelier their info is listed. 

Finally, if simple online/social media searches don’t cut it, remember that there are special tools like Reply.io that offer robust business contact databases, and Findy that can uncover emails and phone numbers from LinkedIn profiles. 

Whichever method you choose, always use the information responsibly and comply with privacy and communication laws. Good luck connecting!
