What Caller ID Reputation does
Caller ID Reputation Inc. is a private B2B SaaS company founded in 2018 and headquartered in Irvine, California, that monitors and remediates how outbound business phone numbers are presented to consumers across the US telephony ecosystem. Its core platform aggregates caller-ID flag data directly from major US carriers (Verizon, AT&T, T-Mobile, Spectrum) via analytics providers (TNS, Hiya, First Orion) and from consumer call-blocking apps (Nomorobo, Robokiller, YouMail, TrueCaller). A proprietary Device Cloud uses physical mobile devices — not simulations — to test how numbers actually display on iOS and Android endpoints across carrier networks.
The product suite centers on Phone Number Reputation Monitoring (real-time flag detection via dashboard and REST API), an STIR/SHAKEN Attestation Tester (A/B/C attestation scoring), Phone Number Scoring (0–100 reputation index), and a Call Blocking Redress workflow. Adjacent products include DialRight (DNC/RND lead-list scrubbing) and a Free Caller Registry. The premium tier is a Remediation Managed Service in which a dedicated team actively submits label-correction requests to carriers and call-blocking apps on behalf of clients, delivering an average 79% flag-rate reduction within two weeks and 48–72 hour typical removal times. The platform integrates with Twilio and operates over REST APIs with webhooks.
The business model combines annual subscription contracts (with a freemium entry: audit up to 5 numbers for 5 days) and quote-based enterprise pricing for managed remediation. The customer base spans outbound call centers, telemarketing firms, customer-service organizations, and verticals including healthcare, financial services, insurance, non-profits, utilities, and education. The company employs 11–50 people, holds SOC 2 Type 1 and Type 2 compliance, is a member of the Robocall Exchange (REACH), and has tracked 45M+ caller-ID flag events since 2021 with 14.5M+ events analyzed in 2025 and 40,000+ numbers currently monitored for clients.

Caller ID Reputation competitors and assessment
Company assessmentDirect peers
- Hiya: Hiya delivers caller ID, spam labeling, and call-reputation intelligence to carriers and enterprises (including AT&T and Samsung Smart Call). It is a primary third-party data source CIDR monitors and a direct competitor in the reputation-data layer.
- YouMail: YouMail provides call-blocking, voicemail, and caller ID reputation services that feed into FCC/ITG data. It serves overlapping consumer and enterprise audiences and competes in the same remediation ecosystem CIDR addresses.
- Numeracle: Numeracle provides identity management and call labeling/scrubbing solutions for outbound call centers and enterprises, competing head-to-head with CIDR in phone number reputation monitoring, remediation, and STIR/SHAKEN attestation services.
- First Orion: First Orion provides phone number risk scoring and call labeling for T-Mobile and Ting. It is both a data source CIDR remediates against and a competitor offering caller ID reputation products to carriers and enterprises.
Emerging players
- Robokiller: Robokiller is a leading consumer call-blocking app where flagged numbers are redressed via CIDR's Call Blocking Redress service. It is an adjacent participant in the flagging ecosystem rather than a direct enterprise competitor.
- Nomorobo: Nomorobo is a popular consumer call-blocking app whose flagging contributes substantially to the data CIDR monitors. It is a remediation target for CIDR and an adjacent participant in the call-reputation ecosystem.
Others
- CallRail: CallRail provides call tracking, recording, and analytics for marketing and sales teams. While not a direct competitor in number reputation, it overlaps with CIDR's call-center and SMB customers and offers complementary conversation analytics.
- Invoca: Invoca provides AI-driven call analytics and conversation intelligence for enterprise marketing and contact centers. It overlaps with CIDR's enterprise customer base on the call intelligence side, though it does not compete in reputation scoring.
Broad incumbents
- Truecaller: Truecaller is a global consumer caller ID and spam-blocking app whose scoring CIDR monitors and remediates. It is a broader incumbent in the caller ID category with primarily consumer rather than enterprise distribution.
- TNS (Transaction Network Services): TNS operates robocall identification and call-blocking infrastructure for Verizon and Spectrum and offers enterprise call analytics. It is both an integration partner CIDR routes remediation through and a broader incumbent in telecom analytics.
