II. Paid Options
When choosing the best tools to look up phone numbers, our goal was clear, to find options that give verified, accurate, and easy-to-access numbers.
Here’s what we looked at:
This checklist helped us pick the most reliable paid and free tools for looking up phone numbers in 2025.
Here’s a quick snapshot of the best free and paid tools to look up phone numbers:
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.
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:
LinkedIn helps you confirm identities and, where available, gives you direct access to the phone numbers people have chosen to share.
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:
Google is best when you need a company’s contact number quickly, especially for offices, branches, or general inquiries.
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:
Whitepages works best for U.S.-based phone numbers, but keep in mind that some listings may be outdated or incomplete.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.
If you only need a few verified phone numbers, Lusha is a good freemium option.
It offers 40 free credits per month, which you can use to reveal direct phone numbers of professionals.
How to do it:
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.
If you want the most accurate and reliable way to look up someone’s phone number, LeadsForge is the best option.
It gives you access to a 500M+ verified contact database and uses real-time verification to ensure every phone number is accurate.
Plus, you get 100 free credits when you sign up, making it easy to try before upgrading.
Here’s how to do it:
LeadsForge is the best way to look up verified phone numbers, especially if you need real-time accuracy, bulk lookups, and high connect rates.
With 100 free credits, it’s a risk-free way to start finding the right contacts immediately.
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:
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.
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:
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.
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:
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.
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:
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.
