What is a business phone number list?

A business phone number list is a list of leads or prospects that includes phone numbers that sales reps can use for sales and prospecting

The list may include direct dial numbers or cell phone numbers and information about the prospect, such as their name, job title, and the company they work for.

What’s the difference between cell phone numbers and direct dials?

A direct dial is an office phone number assigned to a person in a company, while B2B cell phone numbers let you speak to a prospect directly, even if they are not physically in their office or at their desk.

With cell phone lists, you can speak to prospects directly because they carry their phones with them. And when using direct phone numbers, you usually have to get past a gatekeeper—an assistant or a receptionist.

Where to get an accurate list of business cell phone lists for cold calling?

The best way to get a list of phone numbers is to use telephone databases like Cognism. To create targeted account lists, you can use advanced filters like company size, revenue, location, industry, and event triggers (funding, hiring, etc.).

Next, you can narrow down the results with contact-level filters to find business decision-makers. Then you can reveal their contact details (verified cell phone numbers and B2B email addresses) and export them to your CRM.

What to look out for when buying a cell phone numbers list?

When you buy a phone number list, look for a reliable source of verified and compliant data in your target market. 

Web scraping companies often provide basic data, filled with gaps and/or outdated phone numbers to people who have no interest in your product or service. They often provide lead data that violates compliance privacy regulations, such as GDPR in Europe or CCPA in the US.

Cognim’s manually-verified cell phone numbers database is ideal for building cold calling lists. We confirm the contact’s identity, check Do Not Call lists worldwide, and comply with European GDPR data protection rules and CCPA in the US.

Is using a cell phone numbers list for cold calling legal?

Yes, provided you have a legitimate interest in contacting leads about your product or service. 

You must also appropriately handle your prospects’ information, give them an easy way to opt out of future calls, and scrub the numbers against do-not-call lists.
