The phone rings, and your called party has a few seconds to decide whether to answer. Successful outreach over the phone can be a challenge when numbers are labeled as Spam, a Scam, or a Fraud. These negative labels significantly reduce the likelihood of your calls being answered. Call blocking at the network level further compounds the problem, leading to lost opportunities, decreased productivity, and lower customer satisfaction.
Based on Numeracle's analysis of outbound phone numbers used across multiple industries, we've identified that an average of 25% of a business's phone numbers are typically at risk for improper call labeling. These labels prevent calls from being answered and, when combined with call blocking, can lead to substantial losses in productivity and customer satisfaction equal to a financial loss of millions.
When a business’s phone number gets labeled as Spam, Scam, or Fraud, it can only be fixed through a validated remediation process to restore its reputation across the major wireless carriers, with the result being the removal of the label.
Numeracle’s Entity Identity Management Platform provides this remediation process, proactively correcting negative call labels while offering ongoing monitoring, allowing businesses to continue their outreach without disruption. Our platform gives customers access to real-time reputation dashboards, ensuring fast removal of improper labels with minimal effort on the part of the business. Let's look at how our remediation services have helped our customers over the past year.
Numeracle reviewed yearly status reports on phone numbers registered across the wireless ecosystem via our Entity Identity Management Platform and the number of successful remediations conducted in 2024 with a comparison of contact rates before and after improving number reputation with our remediation services.
Across 747,440 numbers vetted and registered across the 2,013 entities registered as of the end of 2024, a total of 112,230 numbers were identified as Spam, Scam, or Fraud that were successfully remediated with 1.5 days to resolve the improper labels on average by our team. With the multiple thousand labels remediated this past year, the 112,230 remediations completed in 2024 accounts for about 16% of Numeracle's all-time remediation total of 583,156 negative labels removed over the past 6 years of the study. It also represents a growth of over 83% in remediations since this study was last conducted at the end of 2022.
These results demonstrate how effectively resolving labeling issues can significantly improve outbound calling success and business performance. Once Spam, Scam, or Fraud labels were identified and remediated, most businesses recorded improvements to contact rates in the average range of 1–5%, with outliers experiencing upwards of 20–30% increases post-remediation, significantly impacting positive ROI.
With remediation levels almost doubling in two years, it’s clear the battle to correct labeling issues for legal business is still very much alive and an essential component of outbound dialing. No one business or business type is exempt from improper call labeling events, our trends indicate that remediation projections will continue increasing as more businesses prioritize their calling identities and improve their outreach strategies.

Numeracle provides the only end-to-end identity management solution for full control, consistency, and visibility into your numbers’ status and history, ensuring your calls are displayed correctly across all wireless carrier networks.
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.
Even with the best calling practices, your numbers can still be mislabeled as spam. This can happen due to overly aggressive spam filtering algorithms, incorrect data aggregation by analytics providers, or even if your numbers were previously used by an entity with less reputable calling habits. Numeracle’s Number Reputation Management Solution actively works to correct these inaccuracies.
Removing a spam label can be a complex process. It typically involves identifying which entities (carriers, analytics providers, apps) have flagged the number and then engaging with each of them to request a review and removal. This often requires providing proof of legitimate calling practices and can be time-consuming. Services like Numeracle offer to manage this entire remediation process on your behalf.
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.
