Social media, texting, and email seem to reign supreme, but a phone call remains the most effective way to engage with current and prospective customers. In fact, a remarkable 92% of business-customer interactions still take place over the phone, a testament to its enduring value. As consumers increasingly crave personalized experiences, the importance of voice communication is only poised to grow.
What most businesses don’t know is that 25% of their numbers are at risk of being mislabeled as ‘spam,’ or worse, blocked altogether; this can lead to loss of revenue and a damaged brand reputation with consumers and customers. This risk is amplified by a complex interplay of factors, and can only be mitigated by taking a proactive approach to phone number reputation management and adhering to best practices.
While designed to combat illegal robocalls, spam labeling technologies have unintentionally trapped legitimate businesses in their cross-hairs, often mislabeling critical calls and interfering with their ability to connect with customers. As these technologies advance and new regulations are introduced, it’s a persistent challenge for businesses to protect their caller reputation and keep their phone numbers label-free.
The consequences of mislabeled calls can be severe, impacting businesses in a variety of ways:
While spam labeling technologies and an evolving regulatory landscape present significant communication roadblocks, they aren’t the sole culprit. Among other factors, unhealthy dialing practices can exacerbate the problem, making businesses more susceptible to negative call labels.
Your dialing habits can significantly impact whether your calls reach customers or get flagged as spam. Here are some common mistakes that businesses make when outbound dialing:
Repeatedly calling a customer in a short timeframe, often called “double dialing,” may seem like a way to increase contact rates. However, it often backfires, triggering spam filters and annoying your customers.
The Fix: Space your calls out strategically, and give customers time to respond.
Customers who register on the National Do Not Call Registry (DNC) expect their wishes to be respected. Ignoring this list can lead carriers to aggressively label your numbers as spam.\
The Fix: Always scrub your call lists against the Do Not Call Registry and honor consumer preferences.
Earl- morning or late-night calls are disruptive and can lead to complaints. High complaint rates are a major red flag that directly contribute to your numbers being mislabeled.
The Fix: Stick to standard business hours to improve the chances for positive interaction.
Contacting current or prospective customers with irrelevant offers is a surefire way to generate negative feedback, increasing the risk of being labeled as ‘spam.’
The Fix: Use an opt-in list, segment your audience, and personalize your outreach.
These numbers may come with incorrect Caller ID names or inherited negative reputations from previous users.
The Fix: Register new phone numbers and verify with your carrier that a recent CNAM (Caller Name) update has been performed. If possible, request numbers that have had a "rest period" of about six months between uses to minimize the risk of inherited negative reputation.
Remember, smart dialing is about more than just reaching customers – it's about respecting them. By implementing these best practices, you'll improve your chances of successful outreach while protecting your brand’s caller reputation.

Phone numbers are often flagged as spam due to a combination of calling behaviors, the number's history, and recipient feedback. High or repetitive call volumes, particularly from a single number, calling outside business hours, and short call durations with frequent hang-ups, signal potential unwanted activity to carriers and spam detection algorithms. Repetitive dialing of the same numbers and calling outside typical business hours can also contribute to spam labeling.
When recipients manually mark a number as spam on their devices or through third-party applications, this feedback is widely shared and significantly impacts a number's reputation. Finally, using outdated or unconsented calling lists increases the likelihood of recipients marking calls as spam. Ultimately, a number's spam status is a dynamic assessment based on calling patterns, historical use, technical validity, and direct user feedback, a challenge that services like Numeracle’s Number Reputation Management solution address through monitoring and remediation.
A multi-faceted approach centered on validating and asserting your trusted calling identity across the ecosystem is necessary to keep your outbound calls from being incorrectly labeled as spam.
Firstly, ensure your phone number is accurately registered with the relevant carrier databases and that your business information is consistent. Secondly, actively monitor your number's reputation across various analytics and call-blocking platforms to identify where the negative labeling originates. Leverage established remediation processes directly with the carriers and analytics providers to dispute the incorrect spam flags, providing them with verifiable proof of your legitimate calling practices.
Finally, consider implementing a proactive phone number reputation management solution like Numeracle’s to continuously validate your business and numbers, thereby reducing the likelihood of future mislabeling and ensuring your calls reach your intended recipients.
The best way to avoid spam labeling isn’t to attempt avoiding it or simply monitoring it—it’s to actively protect your phone numbers through identity-based remediation and number reputation management. Unlike passive monitoring tools that only alert you after a label appears, Numeracle delivers proactive, continuous protection that prevents labels before they appear and remediates them when they do.
Spam and scam labels are often applied to legitimate business calls due to lack of trust signals, inconsistent call behavior, or shared carrier analytics. Numeracle solves this at the source through our Verified Identity KYC process, which authenticates your brand’s authority to use specific numbers, and communicates that legitimacy across the call delivery ecosystem. This identity-based approach enables ongoing remediation with carrier partners, analytics engines, and call blocking apps—ensuring your reputation stays protected, not just watched.
Manual remediation typically involves human agents identifying and addressing spam flags on a case-by-case basis, which can be time-consuming and resource-intensive, potentially delaying the resolution of negative labels, impacting call deliverability, and costing businesses ROI.
However, services like Numeracle offer automated solutions that leverage technology to continuously monitor phone number reputation, detect spam flags, and initiate remediation processes automatically, offering a faster and more scalable way to maintain a positive calling reputation and ensure consistent outreach to customers. The choice between these methods often depends on the volume of calls, the frequency of spam flagging, and the resources available to dedicate to reputation management.
