Phone number lookup is your best bet to ensure your database of contacts is active and real.

But what tool should you be using?

In this post, we’ll share everything you need to know about phone number look-up services and how you can use them for phone number searches when identifying leads.

What is a phone number lookup service?

A phone number lookup service is a tool that allows you to enter a phone number and retrieve information about the person or business associated with it. It is the opposite of a traditional phone book, where you look up a name to find a phone number.

However, some services like lemlist offer this feature where you can look up a name online and get any phone number associated with their professional accounts like LinkedIn.

So when dealing with a new business contact, you can run a quick check to confirm that you’ll be speaking to the right person during a sales call.

How to use phone number lookup tools safely and responsibly

Phone lookup services can be helpful, but you should also respect people’s privacy and their personal information.

So here are a few tips to ensure you remain respectful;

  • Use reliable services

Look for established companies with clear data sources and privacy policies.

Free services might be tempting, but their information might be inaccurate or outdated. This can be a problem for your business.

  • Be cautious of what you find

Only some things you see online are true, especially with free lookups.

Verify information through multiple sources before concluding.

  • Respect boundaries

Fair use policies exist for a reason. Avoid excessive lookups, especially on the same number, to avoid harassment.

Phone number lookup tools for phone number verification

To verify a phone number or business contact, you need the right tool for your specific needs. This is why you need to understand how they work before getting started.

How does a phone number lookup work?

Depending on the software or service you choose, your phone number look-up could work in any of these two ways;

1. Reverse Phone Lookup

This is the most common type of phone number lookup.

You enter the phone number and the software then reviews public and private databases to find information about the owner of the number. This could include the owner’s name, address, location and phone carrier.

In some cases, it would also contain a spam and risk score. Oftentimes, this is used as a phone number verifier.

2. Information retrieved

In this case, you upload a list of contacts, and the software scans through several databases to give you a contact number.

Most of the time, the contacts you upload could be either email addresses or LinkedIn profiles.

Tools that offer this often provide a Chrome extension so you can find leads and their phone numbers straight from within LinkedIn.

With lemlist, you can find accurate phone numbers for your leads with the Phone number finder. Finding phone numbers can be time-consuming; doing it with lemlist can save you hours of work.

lemlist sources its phone number data from ContactOut, one of the most reliable contact databases online, ensuring high accuracy.

With lemlist, you can find your leads’ phone numbers in several ways:

  1. Straight from within LinkedIn with the Chrome extension
  2. By uploading a CSV with LinkedIn profile URLs
  3. When sending leads from the leads database to a campaign

Free vs. paid phone number look-up services

If you’re considering whether paying for a phone number lookup service or tool is worth the price, you should compare both options.

Free services are great for smaller businesses who want to verify a few contacts. They offer straightforward features with simple interfaces. However, they tend to offer lower accuracy, limited information and sometimes ads.

Paid services, on the other hand, often get their details from private databases, so they offer more comprehensive information. These paid services also offer additional features and higher accuracy.

So it all boils down to what your business needs at a particular time. Nevertheless, if you’re going to use this system on a regular basis, we recommend investing on a paid plan.
