How to Buy Cell Phone Numbers List for B2B Outreach

In B2B sales, the ability to reach decision-makers quickly and efficiently can make or break your outreach efforts. However, getting past gatekeepers within an organization can be exhausting, and waiting for prospects to respond to cold emails is a surefire way to miss your revenue targets. 

Primarily due to the rise of remote and hybrid work, decision-makers have become increasingly mobile and harder to reach through traditional channels (work phones, email, etc.). As a result, cell phone numbers have emerged as a critical tool for effective prospecting. These direct lines of communication can dramatically improve your ability to connect with potential customers, nurture leads, and ultimately close business.

However, acquiring and utilizing cell phone numbers for your outreach requires a careful balance of data quality, legal compliance, and thoughtful planning. 

In this article, we’ll cover everything you need to know about effectively purchasing and using cell phone number lists in your outreach to ensure that your prospecting efforts are powerful and professional. 

Key Considerations Before Buying Lists of Cell Phone Numbers

Buying a cell phone numbers list is a bit murky and fraught with potential risks; however, the rewards of connecting with more decision-makers are well worth the effort. When buying a cell phone number list, choosing the right provider can mean the difference between seeing success and ROI or angry “no’s” and even lawsuits.

Before you make any purchases, you should aim to gather as much information as you can about your future provider, including: 

Data Accuracy & Recency: 

On average roughly 30% of the total U.S. total workforce changes jobs every year. This makes the accuracy and recency of the phone numbers (or any B2B contact data for that matter) critical to the success or failure of your campaigns. A poorly maintained phone list will have you wasting time, energy, and resources calling folks who have moved companies, been promoted, or are no longer in the market for your solutions. To combat this, look for a data provider that uses rigorous verification processes and update processes to maintain the accuracy and currency of their data.

Privacy Compliance: 

In a world of increasing consumer privacy, compliance with local and global protection laws is non-negotiable. Failure to comply with regulations can irreparably damage your brand image and result in millions in fines. Choose providers that are transparent about their compliance measures. In general, providers that do comply with any regulations will provide clear statements and documentation on how they ensure their data adheres to all relevant regulations. Here are a few to look out for: 

  • TCPA and CAN-SPAM Act: Verify that the provider complies with the Telephone Consumer Protection Act (TCPA) and CAN-SPAM Act. These regulations govern how businesses can contact individuals on their mobile devices and require specific permissions and opt-out mechanisms.
  • GDPR and CCPA: These two regulations apply if you’re dealing with international clients or residents of California specifically, you have to make sure your provider’s data complies with the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA). These regulations determine how the sale, handling, and use of personally identifiable information (like a cell phone number) can be used by a business. 

Targeting & Filtering: 

To get the most out of your cell phone number list, you should be calling buyers that fit your ideal customer profile (ICP). To achieve this, look for a provider that offers segmenting capabilities such as industry, job titles, company size, geographic region, etc. Most providers do have some degree of filtering. Some providers upcharge for filtering and some include it with the price of the subscription, so dig around and explore which provider has exactly what you need to be successful.

Provider Reputation: 

Buying a cell phone number list is an exercise in trust. You’re staking your company’s reputation, time, and money on a provider delivering on their promise. In your search for the right b2b data provider, look for those with a proven track record of delivering high-quality data and ongoing support even after the sale. Review websites like G2, Capterra, and Trust Radius are good places to start, but also read through a company’s case studies to see how they’ve helped companies like yours. Reach out to your professional network for information from colleagues or acquaintances who have worked with a specific provider previously.


Of course, we’re always proponents of quality over everything, but realistically, budgets are a large factor in any purchase decision. When looking to onboard any potential provider, ask about or research their pricing plans. Do they charge a flat monthly fee for unlimited access? Is their pricing tiered or usage-based? Do they charge extra for integrations or specific use cases? All of these questions will help you understand if they will be a good fit for your needs as your company continues to grow.

Best Practices for Using Cell Phone Numbers in B2B Outreach

Once you’ve chosen your provider and secured your list of cell phone numbers, now the real work begins. 

Here are some best practices to follow to maximize the effectiveness of your outreach: 

Personalize Your Outreach: By now, this should be a given for any prospect outreach, but especially if you’re taking the time to call decision-makers on the phone. Make sure you research the company and contact before reaching out (not during the call). 

Use the prospect’s name and reference relevant details about their company, industry work history, and interests to tailor your pitch to address specific pain points or opportunities you’ve identified. This will help show that you’ve done your homework and understand their business context. You should also have a clear and concise value proposition ready as well as answers to common objections or questions.

Lead with Value: This goes hand-in-hand with the previous point – every interaction you have with your prospect should offer value. Share insights, industry trends, case studies, webinars, or other useful content that can help them solve their business challenges. 

Focusing on building long-term relationships and demonstrating a genuine interest in their success rather than just making a quick sale will help solidify you as a trusted partner rather than just somebody trying to close a deal. 

Be Mindful of Timing: Timing your calls to the right time of day and day of the week can be a make-or-break factor in your phone outreach. Research from CallHippo found that among the more than 15,000 calls studied across 30+ countries, by far the best time to make a B2B cold call is Wednesday between 3 pm and 5 pm. 

You should also take into account your prospect’s time zone, not just your own. It may be 3 pm where you are, but a prospect across the country (or globe), may be fast asleep or sitting down to family dinner (i.e. times you absolutely do NOT want to be calling). 

Build a Multi-Channel Approach: Phone outreach is just one component of a well-built prospect engagement strategy. Layering phone calls into your outbound email sequence or social media outreach and coordinating with marketing to run display or social media ads with consistent messaging can help build a cohesive experience and reinforce your value proposition. For example, your full motion could look something like this:

    • Send an initial outreach email introducing your company and solution. 
    • Follow up the email with phone calls to schedule a demo. 
    • If the prospect doesn’t answer, send a text message.
    • Your marketing team runs a LinkedIn ad campaign against the list of prospects who didn’t initially convert.
    • Send a LinkedIn message to complement your email outreach. 

The more channels and touchpoints you can create with prospects, the better chance of engaging and converting them. 

Be Persistent, But Not Pushy: Here again, the same rules of sales apply, don’t rely on a single contact attempt. A study by HubSpot found that 80% of sales require five follow-up calls after the initial contact, but 44% of salespeople give up after one. If the prospect doesn’t answer, try again in a day or two, or at a different time of day (still within working hours) to demonstrate tenacity and build the relationship over time. 

However, one word of caution here. Respecting contact preferences and opt-out requests is critical to maintaining good standing in the market. If a prospect does not want to be contacted, allow them to do so by providing easy-to-use opt-out mechanisms in all of your communications and honoring those requests quickly.
