LinkedIn Phone Number Search: How to Do It in 2025

LinkedIn Chrome extension 

When it comes to low-volume LinkedIn search, LinkedIn scrapers are undeniably the top option. These are lightweight, free, and straightforward Chrome extensions that simply live in your browser and stay ready to assist with your LinkedIn prospecting efforts. 

The way they work is pretty simple — you install a reliable LinkedIn scraper Chrome extension, for instance, Findy, which will only take a minute or two. 

Once installed, it will work in the background when you’re on LinkedIn, looking for contact information that it can extract. That could include emails, phone numbers, company data, and more, depending on what’s listed or connected to each profile across other sources.

So once you come across a relevant decision-maker’s LinkedIn profile that you would love to call and discuss a potential partnership, for example, Findy will automatically source and extract their email and phone number, and validate both in real time. 

You won’t have 100% success rates with Chrome extensions, but for most LinkedIn profiles, you’d be surprised how often they get the job done. 

All in all, Chrome extensions are the perfect solution to finding leads on LinkedIn for account-based sales or marketing, and one-off or low-volume prospecting. 

Moreover, these LinkedIn scrapers seamlessly connect to CRMs, sales engagement platforms, etc., allowing you to export those phone numbers (along with emails, company info, and more) for further business activities. 

Findy, for example, seamlessly connects with Reply.io — one of the leading AI-powered sales outreach tools, enabling you to export those phone numbers and emails into tailored, multichannel outreach sequences, and make your calls directly through the platform. 

Lead database 

While Chrome extensions are sufficient for a few leads here and there, when it comes to high-volume prospecting, you’ll probably need more power. 

One of the top solutions is leveraging a B2B lead database — a cloud-based database containing tons of contact, prospect, and company information on millions of professionals across industries and geographies. 

On an individual or low-volume level, if you’ve come across a few prospects on LinkedIn and wish to find their phone numbers — simply enter their names and surnames in your chosen lead database (just make sure it’s a reputable one). If they work in B2B, tech, etc., chances are they will be in that database. 

These contact databases pool millions (in some instances billions) of contact records from LinkedIn, company websites, CRM scraping, third-party enrichment APIs, and other external (and legal) sources. 

On a high-volume, list-building level, you could simply bypass the whole LinkedIn step altogether. The leading lead databases have numerous search filters that allow you to narrow down your search, and given that most LinkedIn profiles are in this database, you can find relevant leads along with phone numbers right through these platforms. 

Reply’s lead database is one of the most robust options available on the market, containing over 1 billion live contacts, native real-time email/phone number validation, and countless search filters. 

This way, you not only get validated phone numbers but also enriched prospect profiles with information you can leverage to spark better conversations and drive engagement.

AI sales agents 

AI has taken the tech world by storm, so it comes as no surprise that there are now ways to leverage AI to find phone numbers from LinkedIn. 

So instead of sourcing through LinkedIn profiles or filtering through a database manually — what if you could train an AI assistant to do that for you? This is exactly what modern AI sales agents, aka AI SDRs, can do. 

These AI agents are some of the most powerful business tech on the market, and once you’ve trained them on your product, service, or outreach goals, they will autonomously search through lead databases, LinkedIn, company websites, and other external sources for targeted leads. 

They will uncover emails and phone numbers while they’re at it, along with enriched, verified data points like company size/budgets/news, prospect news like job changes or achievements, and buyer intent signals — all helping you connect with leads on a more personal level. 

One of the leading AI SDRs on the market is Jason AI, completely taking over the entire sales prospecting process from prospecting to booking meetings. 

Here’s how it works in action:

1. You enter your ideal customer profile (ICP) and any targeting preferences;
2. Jason AI pulls the most target leads from its integrated database, LinkedIn, and more; 
3. It then enriches each prospect profile with verified data; 
4. It generates a tailored multichannel sequence for each unique lead, spacing emails, LinkedIn messages, and phone calls for maximum engagement; 

1. Each message and email is hyper-personalized with thoroughly-researched prospect and company data; 
2. Finally, it will handle incoming responses (including common objections) and book meetings on your behalf, passing along purchase-ready leads to your sales team. 

With Jason AI, you get unparalleled consistency — every lead is vetted, every message is personalized, every phone number is validated, and every follow-up action is timed perfectly.

Manual search  

We deep-dived into technology for LinkedIn phone number search, but let’s not skip the obvious. Sometimes, the number you need is just sitting there in plain sight on a LinkedIn profile. 

This is definitely not a bullet-proof tactic since most LinkedIn users choose to either not add or hide their phone numbers from public view, but in some cases, you might just be lucky enough.

This method is very straightforward. First, visit the person’s profile. In their profile “header”, next to their name and headline, click the “Contact Info” button. If they’ve listed their phone number and you’re a 1st-degree connection, it’ll show up.

If you’re not yet connected on LinkedIn, send a connection request with a short and friendly message, wait until they accept, then check again.

You could also scan the “About” or “Experience” sections — occasionally, certain professionals include their phone numbers there specifically for inbound communications. This is especially true for consultants, freelancers, or founders. 

While on this topic, another neat trick to have in your back pocket is to simply use the power of your search browser. You could try different variations like:

• “Name Surname” phone number 
• “Name Surname” phone number site:[company website] 

It’s rare, but not impossible.

Just ask 

Sometimes the best tactic is the simplest.

If you’ve already had some form of interaction with a person on LinkedIn, or even if you’ve simply just connected and reacted to a few posts here and there, you can simply ask for their number. 

Only if you do it the right way, that is, it has to be smart, professional, and respectful. 

Here’s what not to say:

“Can I call you? What’s your number?”

“Hey, can I please have your number?”

Or anything else that’s even remotely similar to those examples. 

Instead, here’s an example of a professional, low-pressure, and value-driven LinkedIn message to ask someone for their contact number:

“Hey Alex, I’ve got a few quick ideas that could help [Their Company] with [pain point]. Would you be open to a 5-min call? Totally understand if now’s not the time — but if yes, what’s the best number to reach you?”

People are much more likely to respond when they know what the call is about, how long it’ll take, and that it’s not just another general sales pitch.

Most importantly, if you don’t get a reply or if the answer is “No”, don’t push. Instead, you can simply follow up once or twice with a lighter message down the line, or perhaps with an effective cold email. 

In any case, polite persistence wins the game.

LinkedIn search by phone number

Sometimes, you may need to do things “backwards”. If you have a phone number from a lead list, business card, data tool, etc., but want to find the LinkedIn account of the person it belongs to. 

So can you search LinkedIn by phone number? The answer is yes and no. 

There are a few methods to search LinkedIn by phone number, but none of them involve the platform. Instead, you could try:

• Google search → enter the number in quotation marks with the LinkedIn domain — [“(123) 456-7890” site:linkedin.com]. If the number is present and public absolutely anywhere on LinkedIn, Google will catch it, sometimes even if it was there in the past but has since been removed. Similarly, you could simply enter the number in quotation marks, hope it gets a hit for a name/surname, and then search that person on LinkedIn. 
• Enrichment tools → certain LinkedIn scrapers, lead databases, and sales outreach tools like the ones discussed have reverse lookup features. This means you could enter a phone number, and if there’s a hit, you’ll get a full prospect profile along with additional information, including their LinkedIn profile (or at the very least their name and surname for manual LinkedIn search).
• Messengers & social media → though this is a bit of a shot in the dark, you could also try saving the phone number to your contacts, and then checking WhatsApp, Telegram, Instagram, etc. If they have their phone number synced to a messenger or social media app, you’ll often see their profile photo and/or full name, enough to trace them on LinkedIn manually. 

All in all, LinkedIn search by phone number is manual and unpredictable, but in certain cases enough to get the job done.

Phone calls as part of your multichannel strategy 

Finding phone numbers on LinkedIn is just half the battle — the other half is how to use them.

Even the most targeted phone number, along with the most well-rehearsed call script, won’t get you far if your call comes out of nowhere. Cold calls on their own, especially in 2025, rarely convert into meaningful conversations, let alone into fruitful sales or partnerships. 

But a phone call that’s part of a multichannel sequence? That’s where the real magic happens.

With AI-powered sales engagement platforms like Reply.io & Jason AI SDR, multichannel outreach has become entirely automated and enhanced. 

Each prospect is highly targeted, vetted, and researched for relevant data points. Each message leverages that uncovered data to craft hyper-personalized messages. Each sequence channels, touchpoints, and timing are tailored to leads based on tons of historical data that shows which strategy works best for each unique case.  

So while you (or your sales team) will be the one(s) doing the actual phone calls, they will now be supplemented with automated, AI-driven emails and follow-ups, LinkedIn connection requests and messages, SMS, WhatsApp, and more — increasing the likelihood of those conversations going well.  

For reference, here’s what a modern, effective outreach sequence might look like with Reply.io:

In this example, the person you’re calling will already have at least some memory and understanding of who you are and why you’re calling, which will definitely help build rapport in those crucial first few seconds. 

If you crafted an effective initial email and they’ve actually read it, they will also likely have checked out your company and studied your value proposition, making the conversation much more productive, regardless of how it goes.  

And if the phone call results in a “not a yes and not a no” territory, then following up on LinkedIn after a few days or weeks (depending on the unique case) will only help reinforce the possibility of a future deal. 

In summary, phone calls work — but not so much when they’re flying solo.
