In 2025, many enterprise calls were still improperly blocked or labeled as spam. These labels caused phone calls to display incorrectly on customer devices, lowered answer rates, and damaged brand trust.
Numeracle helped solve this by protecting phone numbers and removing incorrect spam and scam call labels through our Number Reputation Management (NRM) solution. By the end of 2025, Numeracle was protecting over one million enterprise phone numbers, supporting large-scale labeling remediation, and enabled millions of branded phone calls.
As carriers work to protect consumers from illegal robocalls, spam labeling continues to affect legitimate enterprise callers while their labeling algorithms are refined for greater accuracy.
Businesses need two things to ensure calls are delivered, clearly identified, and answered:
Numeracle’s Platform reports on the labeling status of phone numbers and the completion of successful remediations across all major wireless carriers.
This case study uses aggregated platform data to assess how remediation activity evolved throughout 2025 while uncovering vulnerable key industries and insights into branded calling enablement.
Numeracle measures success using KPIs that reflect durable trust, not short-term remediation alone:
Enterprise calls continue to be mislabeled as spam or blocked when there isn’t enough clear information about the caller.
All calls are subject to blocking and labeling algorithms that automatically evaluate whether a call appears trustworthy or suspicious. These systems are designed to protect consumers from fraud and bad actors who continue to exploit the voice channel. As carriers improve these protections, they rely on identity signals to decide which calls can be trusted and which should be labeled.
When a phone number isn’t clearly linked to a verified business identity, even legitimate calls may be flagged by mistake. Spam labels prevent calls from being answered and, when combined with call blocking, can lead to lost productivity, missed conversations, and lowered satisfaction, especially for businesses that depend on calling to serve their customers.
When a phone number is blocked or labeled, it can only be fixed through a remediation process to restore its reputation across the wireless carriers, with the result being the removal of the label.
Numeracle’s Entity Identity Management (EIM) platform verifies and manages the identity behind enterprise phone numbers and provides this remediation process through a Number Reputation Management solution.
Using vetted and verified enterprise identity information, we advocate on behalf of customer calls with the wireless carriers to keep them protected from blocking and remove any spam labels that may reappear due to dialing practices or algorithm changes. This allows businesses to continue their outreach without disruption and monitor number status with easy-to-use reputational dashboards.
Numeracle evaluated quarterly snapshots of spam labeling data throughout 2025. Each quarter represents a point-in-time view, showing how enterprise calling continues to be a priority.
In 2025, Numeracle expanded protection to 2,940+ verified entities and more than 1,032,800+ phone numbers as enterprise adoption accelerated. Throughout 2025, Numeracle continued to protect up to 99% of customer numbers from negative labeling, even as overall exposure increased.
Numeracle completed 161,440+ remediations in 2025 alone, representing a 44% increase since last year, and contributing to 805,600+ total remediations all time.
The continued remediation activity directly tracks with the expansion of protected numbers and entities that onboard with spam labels, the growth in customer dialing volumes, and ever-changing reputational scoring of calls that causes phone numbers to experience repeat labeling.
Because carrier algorithms dynamically reassess calling behavior, spam labels may reappear when dialing patterns change or when carrier algorithms are updated in response to new threat signals, making ongoing identity management and remediation essential to maintaining call trust.
Because of this fact, it is important to partner with a solution provider that can keep the majority of your numbers spam-label free, while working on remediating repeat labels on your behalf and consulting you on how to improve your dialing practices.
Numeracle enabled and delivered over 66.8 million Smart Branded Calls with a Caller ID Name in 2025 on phone numbers that were protected from being overridden by a spam label. This success demonstrates that prioritizing your calling identity is the recommended prerequisite for branded calling to display correctly and consistently across carrier networks.
Numeracle observed significant increases in remediation activity across multiple high-trust industries, reflecting increased adoption of reputation management services in these sectors in 2025.
Industries with high outbound calling volumes are more frequently evaluated by carrier algorithms, especially in sectors that are common targets for impersonation and fraud. This sustained exposure increases the likelihood of spam labeling and call blocking for legitimate enterprises due to dialing patterns and evolving risk models.
As organizations in financial services, retail, education, utilities, and student financial services adopt reputation management, remediation activity reflects both correcting existing labels and managing re-labeling driven by ongoing algorithmic scrutiny. This reinforces a critical reality: for high-volume callers, call trust is not a one-time fix, but requires continuous, proactive identity protection.
The growth in protected entities, protected phone numbers, and successful branded calls confirms that enterprises prioritizing identity management gain measurable delivery and trust advantages. The 2025 shift reinforces how call trust is not achieved through episodic fixes. It requires continuous, verifiable identity management embedded directly into enterprise communications infrastructure.
Numeracle’s Entity Identity Management (EIM) platform operationalizes the insights from this case study to deliver continuous, automated protection of phone number identity at scale.

Call remediation is the process of removing incorrect spam or scam labels from legitimate enterprise phone numbers across wireless carriers. It is important because spam labels reduce answer rates, damage brand trust, and can block time-sensitive or customer-critical calls from being delivered.
Enterprises fix spam labels and call blocking by verifying their calling identity, protecting phone numbers from negative reputation signals, and completing carrier-approved remediation to remove incorrect labels.
