6 Best Ways to Look Up Someone’s Phone Number 

Before you start using advanced tools, it’s always better to begin with free sources to get phone numbers.

One of the most effective places to start is LinkedIn, especially when you’re looking for business contact numbers.

#1 - Use LinkedIn to Look Up Phone Numbers (Free)

LinkedIn is one of the most reliable platforms to find professional contacts and, in some cases, their phone numbers

Many users list their numbers in their Contact Info section, making it a quick way to get direct information.

Here’s how to find it:

  1. Search for the person by entering their name + company in LinkedIn’s search bar.

  2. Open their profile and verify their job title, company, and location to confirm you’ve found the right person.

  3. Click on the “Contact Info” section, if they’ve shared a phone number, it will be displayed here.

  4. If no number is listed, keep their name and company handy; you’ll need these details for other lookup tools.

LinkedIn helps you confirm identities and, where available, gives you direct access to the phone numbers people have chosen to share.

#2 - Use Google to Find a Company’s Phone Number (Free)

If you’re trying to reach a business, the fastest way to get their phone number is by using Google. 

Most companies list their main line or branch numbers on their Google Business Profile or website.

How to do it:

  1. Type the company name + “phone number” into Google.

    • Example: Starbucks phone number

  2. Check the Business Profile box that appears, it usually shows the official number right away.

  3. If you’re looking for a local office, add the city or neighborhood to your search.

    • Example: Starbucks phone number San Francisco

  4. For more details, click through to the company’s site and check their Contact Us page.

  5. If only a main line is listed, call it and ask to be connected to the right person or department.

Google is best when you need a company’s contact number quickly, especially for offices, branches, or general inquiries.

#3 - Look Up Phone Numbers in Whitepages (Free)

Whitepages is one of the most popular free tools to look up someone’s phone number in the U.S. 

It works like a digital phonebook, pulling data from public records to show available personal and business phone numbers.

How to do it:

  1. Go to whitepages.com and click on “People Search.”

  2. Enter the person’s full name and, if possible, their city or state to get accurate results.

  3. Check the search results and match profiles using location, age, or known addresses.

  4. Open the correct profile, if a phone number is publicly listed, you’ll find it here.

  5. Use the reverse phone lookup option if you already have a number and want to know who it belongs to.

Whitepages works best for U.S.-based phone numbers, but keep in mind that some listings may be outdated or incomplete

For the most accurate and verified numbers, paid lookup tools are often required.

#4 - Use Lusha’s Free Plan for Limited Phone Number Reveals

How to do it:

  1. Go to lusha.com and sign up for a free account.

  2. Install the Lusha Chrome extension or use their web dashboard.

  4. Use 1 free credit to reveal the phone number if it’s available.

  5. Save the number immediately, you only get 40 free credits per month.

Lusha’s free plan works best when you need just a handful of verified phone numbers

For bulk lookups or larger campaigns, you’ll need a paid solution.

#5 - Use LeadsForge for Verified Phone Numbers (Paid)

ZoomInfo is one of the most popular tools for finding verified phone numbers at scale. 

It’s designed for teams that need to search, filter, and export large volumes of B2B contact data quickly. 

While powerful, it’s also costlier than most alternatives and its pricing is not publicly transparent.

How to do it:

  1. Go to zoominfo.com and sign in or create an account.

  2. Use People Search and apply filters like name, company, job title, location, or industry.

  3. Open the matching profiles to view available verified phone numbers and other contact details.

  4. Add selected contacts to a list and export or sync them directly to your CRM (depends on your subscription plan).

  5. For larger campaigns, use list upload or enrichment to fetch phone numbers in bulk.

ZoomInfo is a paid solution best for teams managing high-volume prospecting

It offers extensive B2B phone number coverage, but it’s costlier than most tools and the pricing is not publicly available, so you’ll need to request a quote.

Why Free Methods Aren’t Enough to Look Up Phone Numbers

At first, free methods feel like the easiest way to find someone’s phone number.

Who doesn’t like a quick Google search, checking LinkedIn, or using a free directory like Whitepages? 

But when it comes to getting reliable phone numbers you can actually use, these methods often fall short.

Here’s why:

  • Many free databases are outdated, so you might end up dialing numbers that no longer work.

  • You usually get generic company numbers instead of the person’s direct line.

  • Free tools often limit how many phone numbers you can see, which makes them useless if you need more than a handful.

  • Without real-time verification, there’s no way to know if the number belongs to the right person.

In short: free methods are okay if you just want to check a single contact or confirm basic info. 

But if your goal is to consistently reach the right people, especially for sales, recruiting, or lead generation, you need tools that provide verified phone numbers you can trust, like LeadsForge or ZoomInfo

They save you time, improve your connect rates, and make your outreach far more effective.

Paid vs Free Phone Number Lookup Tools: Which Should You Use?

Choosing between free and paid phone number lookup tools depends on how many contacts you need, how accurate you want the data to be, and what your goals are.

Here’s a quick comparison to help you decide:

Criteria Free Tools (LinkedIn, Whitepages, Lusha Free) Paid Tools (LeadsForge)
Data Accuracy ❌ Often outdated, no real-time verification ✅ Verified and updated in real time
Type of Numbers Mostly generic company lines Direct phone numbers for decision-makers
Bulk Lookups ❌ Not supported ✅ Lookup hundreds of phone numbers at once
Coverage Limited to publicly available data Global coverage with 500M+ verified contacts
Credits / Limits Very limited (e.g., Lusha = 5 free credits) Flexible plans + 100 free credits with LeadsForge
Integrations ❌ Not available ✅ CRM & outreach tool integrations
Best For One-off checks or validating basic info Prospecting, sales, recruiting, and outreach at scale

Free tools work if you only need to verify a single contact or do occasional lookups.

But if your goal is to consistently reach the right people, especially for sales, recruiting, or lead generation, paid tools are far more reliable.

LeadsForge works both ways. Whether you need just a few phone numbers or a large, verified list, you can start with 100 free credits and only upgrade when you need more.

Final Verdict

Finding someone’s phone number isn’t as straightforward as it seems. Free methods can help for basic checks, but they often leave you with:

  • Numbers that are outdated or incorrect

  • Generic company lines instead of direct contacts

  • Limited options when you need more than a few lookups

If you just need one or two numbers, free tools can work. But when accuracy matters, for sales, lead generation, or outreach, you need a solution that gives you verified phone numbers you can rely on.

That’s where LeadsForge comes in. With 500M+ verified contacts, real-time verification, and 100 free credits to get started, it’s the simplest way to look up phone numbers, whether it’s just a few or an entire list.

LeadsForge gives you a faster, smarter way to look up phone numbers. 

With a massive verified database and 100 free credits to start, you can find the right numbers in seconds and focus on what matters most, talking to real people, not chasing dead ends.
