How Call Centers Find and Verify Phone Number Lists
Inaccurate phone number lists can incur significant costs for call centers, including phone charges and the opportunity costs of agents not reaching potential prospects.
Some estimates suggest inaccurate phone data can cost businesses up to 12% of their revenue. This is why it’s important to find and verify phone number lists.
Plus, the cost per contact, or each interaction with a customer, can range from $3 to $7. This means, when you find real phone numbers for your marketing and sales campaigns, you can save on operational costs and increase agents’ efficiency and productivity.
Reaching real people also lets you enhance customer satisfaction, comply with regulations, improve the reliability of your call center metrics, and maintain a positive reputation for your business.
In this blog, we’ll explore methods and databases call centers can use to find and verify phone number lists—so you can get the right person on the phone, every time.
Key takeaways:
- Accurate phone number lists are crucial for call centers to save operational costs and improve agent efficiency.
- Call centers can find real phone numbers through third-party vendors, web scraping, existing customer databases, and collaborative partnerships. Each method has its benefits and challenges.
- CloudTalk’s virtual and VoIP phone numbers help call centers make a great first impression.

Importance of Accurate Phone Number Lists
While the money you save on operations is a significant benefit, accurate phone number lists can have a positive impact on both calling agents as well as call recipients.
For example, by partnering with integrated AI business calling software CloudTalk, on-demand courier service Glovo increased call volume by 82% and decreased missed calls by 24%. This means agents can focus on connecting with more potential customers, leading to increased sales opportunities, while call recipients enjoy a more streamlined and responsive service experience.
Here are three more reasons why an accurate phone number list is important:
- Improved customer engagement and satisfaction: Accurate phone numbers ensure that calls reach the intended recipients, leading to more meaningful and satisfying interactions with customers.
- Reduced call bounce rates: With accurate phone lists, the number of calls that fail to connect or reach the wrong person decreases, improving overall call success rates.
This improves the reliability of call center metrics and KPIs, enabling better decision-making and the creation of optimized outbound calling strategies. - Enhanced operational efficiency and productivity: Agents spend more time engaging with actual customers and less time dealing with wrong numbers, boosting agents’ efficiency, productivity, and morale.
In case you’re still thinking about winging it, here are three adverse consequences of using incorrect or outdated phone numbers:
- Increased costs: Unsuccessful calls to invalid or out-of-service phone numbers can waste resources, leading to higher operational costs.
- Regulatory issues and penalties: Incorrect numbers can result in calls to individuals who have opted out or are on do-not-call lists, leading to potential legal penalties and compliance issues.
- Damage to brand reputation: Repeatedly contacting the wrong individuals or failing to reach intended recipients can harm the call center’s and company’s reputation.
Methods Call Centers Use to Find Real Phone Numbers
Below, we discuss four methods call centers use to find real phone numbers:
Purchasing from Third-Party Vendors
Call centers often rely on third-party vendors to provide extensive lists of new numbers. These vendors specialize in collecting and maintaining up-to-date contact information segmented by various criteria. But are they reliable?
Reputable vendors make phone number lists segmentable by categories, such as demographics, interests, and other criteria. They also update their lists regularly to maintain accuracy.
Benefits:
- Purchasing phone numbers can save time compared to collecting and verifying numbers independently
- Reduces the need for internal resources to manage and update customer phone number databases
Challenges:
- The accuracy and recency of data can vary significantly between vendors. Low-quality data can lead to high call bounce rates and wasted resources
- Using purchased lists may risk non-compliance with regulations such as GDPR, CCPA, or TCPA
- Premium quality lists can be expensive, and there’s always a risk of not getting a good return on investment if the data is inaccurate or useless
Scraping from Publicly Available Sources
Web scraping is a method in which call centers use automated tools, such as Octoparse, to extract phone numbers from public online sources.
While this cost-effective approach can yield a large volume of data, it requires careful management to avoid legal and ethical pitfalls associated with unauthorized data collection.
Here are some pros and cons of scraping from publicly available sources:
Benefits:
- More affordable than purchasing lists
- Enables targeted data collection based on specific criteria
Challenges:
- Can lead to legal issues if data is collected without consent
- High call bounce rates owing to outdated or inaccurate public data
Using Existing Customer Databases
Leveraging data from existing customer databases is a powerful method that uses contact information already provided by customers, ensuring high accuracy and relevance.
Benefits:
- Existing databases usually contain up-to-date contact information that has been provided directly by the customers, ensuring higher accuracy
- Capitalizing on existing data allows call centers to personalize interactions based on past interactions, preferences, and purchase history
- No additional costs are involved in acquiring new data, making it a cost-effective method
Challenges:
- Customer phone numbers may have changed over time, leading to inaccuracies
- Mistakes during data entry can result in incorrect phone numbers
Collaborative Partnerships
Forming collaborative partnerships with affiliated businesses lets call centers share resources and access new data sets.
However, they require meticulous handling of data privacy and integration to ensure compliance and maintain trust between parties. Here are some benefits and challenges of building collaborative partnerships to find and verify phone number lists:
Benefits:
- Provides new customer segments and comprehensive data
- Economical resource and data acquisition for cost-sharing
- Combines data for detailed customer profiles and better targeting
Challenges:
- Requires strict adherence to privacy regulations
- Technical challenges in ensuring data compatibility and accuracy
- Depends on mutual trust and clear data use agreements
Verification Methods for Phone Number Lists
We have discussed methods to find real phone numbers above; however, that’s not enough. Once you find accurate telephone numbers, you need to verify them for contact legitimacy.
Here are the three main verification methods you can use to obtain accurate phone number lists:
Manual Verification
Manually verifying phone number lists involves human agents personally checking each contact to ensure its accuracy. This thorough process includes:
- Calling numbers to confirm validity: Agents call each number to verify if it is valid and reaches the intended recipient.
- Cross-referencing with other data sources: Agents cross-reference numbers with other databases or publicly available information to confirm their accuracy.
- Updating records: Inaccurate numbers are corrected or removed from the list, and accurate numbers are confirmed and updated to ensure data accuracy and compliance.
Pros:
- Ensures precise data validation
- Detects subtle errors automated systems might miss
- Reduces legal risks with thorough verification
Cons:
- Slow process for large lists
- Difficult to scale for large databases
- Expensive due to labor intensity
Automated Verification Tools
Automated verification tools streamline the process of validating phone number lists, leveraging technology to quickly and accurately confirm the accuracy of contact information.
These tools use algorithms and databases to check the validity of phone numbers.
The process involves:

- Data validation: Validating numbers in real-time by checking for active status and correct formatting.
- Error detection: Identifying and flagging inactive, or incorrectly formatted numbers.
- CRM integration: Integrating with CRM systems to automatically update records with verified information.
Pros:
- Verifies large volumes of numbers quickly
- Reduces the need for manual labor
- Provides uniform validation without human error.
Cons:
- Can be expensive to implement
- May miss nuances that manual checks can catch
- Raises privacy concerns since it relies on third-party data
Real-Time Verification Systems
Real-time verification systems leverage advanced technology to provide immediate validation, enhancing the efficiency and effectiveness of call center operations.
These tools use various methods to check the validity of phone numbers instantly, including:
- API integration: These systems integrate with existing databases and CRM platforms via APIs to perform real-time checks.
- Cross-referencing: These solutions compare phone numbers against large, up-to-date databases to confirm their validity and activity status.
- Carrier lookup: These systems identify the carrier and check if the number is active, ported, or invalid.
- Format verification: These solutions ensure numbers adhere to international and regional formatting standards.
Pros:
- Instant feedback ensures current information
- Handles large data volumes quickly
- Connects with existing systems seamlessly
Cons:
- Depends on external database accuracy
- Can be expensive to implement
- Potential privacy concerns with third-party data
