But how do you find business phone numbers? We’ll show you some of the best ways to get the contact information of key players at your targeted companies.

What is a Business Phone Number?

A business phone number is the telephone number of a company or individual who works at a company. In the B2B world, salespeople seek out the business phone number of key decision-makers, such as:

  • CEOs
  • CMOs
  • CTOs
  • VP and Director Level Contacts
  • Founders

Having the business phone number of these key individuals allows salespeople to place cold calls and start building a rapport with the company.

How to Lookup & Find Business Phone Numbers

It’s not always easy to find the business phone numbers of decision-makers. Rarely is contact information available right on the team’s page which is what makes business phone number lookups so difficult! In most cases, you have to seek out their contact information from third-party directories or websites. 

Here are some of the best ways to find business phone numbers:

Buy Business Phone Numbers

One simple but effective way to find business phone numbers is to buy them. If you have the budget, buying business phone numbers is a quick and easy way to get in touch with the right people more quickly. 

Buying business phone numbers allows you to:

  • Make cold calls
  • Send follow-up cold emails
  • Build up your pipeline

These leads come at a high cost, but they’re also:

  • High-quality
  • Targeted
  • Timesaving

When buying business phone numbers, it’s important to:

  • Consider quality. If the lead information is inaccurate and their database isn’t updated regularly, the information may be useless.
  • Test a sample of their list. Call contacts to ensure their information is correct and updated. With a shift remote work, any SDR or Inside Sales consultant will tell you how important mobile numbers are.

Remember that cheap leads come at a high cost. They waste your time and eat into your budget because they deliver no return.

Finding a quality, reliable provider can be tricky. Here are some of the top-rated options available.

  • Phone number
  • Name
  • Email
  • More

Creative Ways for Getting a Business Phone Number

If you need other creative methods to find phone numbers, you’ll find numerous options in this section that may meet your needs.

Email Them on a Holiday

When businesses are closed, they often have an automatic response, which will have their contact number listed. One trick to get a business’ number is to try and mail them on major holidays.

You may want to:

  1. Mail multiple people at the business
  2. Opt to mail them any time it’s not a business hour

If you try this method and it doesn’t work for you, try one of the other methods in this article.

Tell the Operator You Lost Your Prospect’s Phone Number (Might Be Unethical)

If you need to find a phone number for business stakeholders and have been unable to track their number down, you may want to consider calling the main business number. Initially, ask for the person’s number and see if the operator or secretary would be willing to transfer the call.

There may be times when the operator declines to provide the number.

One method to try and circumvent a declined request for the stakeholder’s number is to call on a different day and mention that you lost the contact’s number. This option is certainly teetering on the side of being unethical, but it is an option to consider.

Check Their Social Accounts for Their Business Phone Number

Businesses rely on social media to help promote their entity and engage with consumers. If you haven’t done so already, you need to try and find business phone numbers on:


LinkedIn is a social media network for business professionals. You’ll want to:

  1. Search the business name on the platform
  2. Find the company page and go to it
  3. Look through the “About” section for the business

The About section of the page may have information about the company, such as its website, address and even phone number. If you’re trying to track down a certain professional that works for the business, you may find them using the same method above.


Facebook is the next platform to check, and many businesses will have their own Facebook Page with information listed. Follow these steps to find phone numbers for the business:

  1. Log into your Facebook account
  2. Click on the search icon 
  3. Type in the business’ name
  4. Visit their Facebook Page

Many businesses will have a detailed About section, which will include the company’s website address, physical address and telephone number. 

If the business has chat enabled, you can even ask for their number in chat.


Instagram may have fewer businesses than Facebook, but a lot of owners are also maintaining a social media presence on the platform. If you have Instagram, search for the business and see if they have their number listed.

Some businesses even have a “call” button on their page to make it easier to call them.

If the business does have an Instagram account and doesn’t list its number, you can send them a message and ask for it. Any active business should be more than happy to provide their contact information to potential customers or clients.

Old School Ways to Find Business Phone Numbers

When the advanced methods to find phone numbers don’t yield results, the old school methods will often work very well. Three main methods to locate business numbers include:


Businesses with a website will have their own “WhoIs” listing, and you may or may not have the opportunity to find the business number using this method. The first step is to do the following:

Many businesses will use a third-party to block their information from being listed as the registrant of the website. However, you may get lucky and find the information on the page. This is the individual or business that registered the company’s domain name.


WhitePages is a massive directory that was started in 1997, and it is filled with the contact information for businesses and people. You’ll want to go to the website’s main page and change the search from “People” to “Business.”

You’ll need to supply the following information:

  • Name of the business
  • City, state or zip code

If you have this information, you may enter in the search information and wait for the results to show. When the results do show you’ll need to click on “show details” and then wait to see what information is available.

You should find a business phone number and address listed, so you can call the business number or go to their physical location if you’re unable to find their phone number. An old school but effective business phone number lookup method.

Look for Press Releases

Press releases were once the most popular way for businesses to announce their opening, new products or services and even alert potential customers to key changes to the business. Google will help you find press releases.

You can begin your search by:

  • Going to
  • Searching the company name + “press release”

The “+” and “press release” are both crucial elements in your search to help you narrow the results to only those that may be relevant.

When scouring the results on Google, look for news announcements. The traditional way to write a press release includes putting the business’ information or the media contact’s name at the end of the release.

The information will often lead you to the right business phone number or the right individual that knows the number. If the press release method doesn’t work for you, it may be time to hire someone else to find the phone number for you.

Professionals have the tools and resources to find the business number for you.

Use Upwork and Fiverr For Business Phone Number Lookups

There are many great tools out there to help you find business phone numbers. But what if you’re short on time and simply can’t add this to your to-do list?

Hiring a freelancer or independent contractor through Fiverr or Upwork is a great option. Both of these platforms allow you to search and view profiles for individuals offering B2B sales prospecting services. 

Hiring an independent contractor will:

  • Save you time
  • Save you money
  • Help you fill your list with accurate data 

Working through a trusted platform like Upwork or Fiverr will also give you peace of mind that the work will be completed on time and be of the quality you expect. If the results don’t meet your standards, you have recourse. 

If you decide to go this route:

  • Check reviews from other buyers. If the seller isn’t meeting expectations, buyers will certainly leave poor reviews. 
  • Make sure that you understand exactly what you’re getting with the service. Ask questions to clarify.
  • Check to see what tools are being used.
  • See how long the seller has been in business or how much experience they have with finding business phone numbers.

Hiring an independent contractor for a business phone number lookup can save you a lot of time and ultimately, money. Finding the right individual is key, so take your time and test out different offerings until you find the right one.

Summarizing How to Find Business Phone Numbers for Sales Prospecting

These are some of the easiest and most effective ways to find phone numbers of decision-makers at your targeted companies. 

Buying business phone numbers instead of a business phone number lookup session is the simplest way to get your hands on this information, although it comes at a higher cost compared to other options on this list. Checking social accounts, email signatures and calling directly to ask for their phone number can also be effective ways to get the information you need.
