}Three analytics engines control spam labeling for 200M+ US mobile subscribers. They flag legitimate numbers as spam, then charge to fix it.
Hiya flags 32% of brand-new, never-used numbers as spam. These numbers have never made a single call.
Hiya and TNS only agree on 16% of flagged numbers. The algorithms are essentially random for legitimate callers.
Incumbents like Numeracle charge $4,000-5,000 for 100 numbers. Same industry creates the problem and sells the cure.
Powers AT&T Call Protect. 400M+ users globally. Their algorithms decide if your call gets through on AT&T.
Powers T-Mobile Scam Shield. Controls spam labeling for the second-largest US carrier.
Powers Verizon Call Filter. Owned by Transaction Network Services. The quietest but equally impactful.

Add numbers. We handle everything else.
One API call. We register across all three analytics engines automatically — Hiya, First Orion, and TNS.
POST /v1/numbers { "phone": "+15551234567" }Reputation scores checked every hour across carriers. You get a webhook the moment something changes.
GET /v1/numbers/num_abc123 → { "risk": "low" }When a number gets flagged, we submit remediation across all relevant carriers automatically. Evidence packets generated and filed.
webhook → { "event": "flag_detected", "action": "remediating" }You get notified when the flag is removed. The number goes back into your active pool. No manual work.
webhook → { "event": "remediation_complete", "risk": "low" }Pay for what you use. No enterprise sales calls. No annual contracts.
Same coverage. 10x cheaper. Actually has an API.
Nobody has built an API-first, self-serve product at per-number pricing. Until now.
The analytics engines (Hiya, First Orion, TNS) flag your numbers. Numeracle charges enterprise pricing to fix it. Everyone else bundles it into a CPaaS. NumRep is the standalone API layer the market is missing.
The only real intermediary between callers and analytics engines. Enterprise pricing, manual dashboard, no API. Built when free channels didn't exist.
Powers AT&T Call Protect. 400M+ users globally. Also sells branded calling ($29+/mo per number) and a free registration portal.
Powers T-Mobile Scam Shield. Offers a free registration portal and branded calling for T-Mobile subscribers.
Transaction Network Services. Powers Verizon Call Filter. The least transparent of the three engines.
Number Reputation Management bundled into Bandwidth's CPaaS platform. Enterprise-focused, requires Bandwidth as your carrier.
Reputation monitoring bundled into their CPaaS offering. Primarily focused on international calling.
Integrate in 10 minutes. No dashboards, no sales calls, no onboarding meetings. Just an API key.
Per-number pricing powered by free public channels. $300/mo for what costs $4,000+ elsewhere.
One integration covers AT&T, T-Mobile, and Verizon. Not locked to any CPaaS or carrier.
If you manage 50+ outbound numbers, you need this.
Bland, Vapi, Retell, custom AI agents
Managing hundreds of numbers with no time for manual reputation work. Need API integration, not dashboards. Number reputation is the #1 infrastructure pain point.
Outbound sales, support, appointment reminders
Losing 15-30% answer rates to false spam labels. Can't justify $40+/number/month from Numeracle. Currently doing nothing and eating the cost.
ARM agencies, FDCPA-compliant callers
Compliant callers getting flagged anyway. Need remediation at scale without enterprise pricing. Every flagged number is lost revenue.
Fintech lenders, mortgage servicers
Regulated callers who can't afford to have numbers blocked. Missed calls create compliance risk. Need monitoring + auto-remediation.
Numeracle was founded when free self-serve channels didn't exist. They had to build carrier relationships. Those channels now exist. Nobody has automated them into a product.
Numeracle founded — no free channels exist. Carrier relationships are the only path.
FreeCallerRegistry.com launches — free CSV registration with all 3 engines.
Hiya Connect and First Orion open self-serve registration portals.
Telnyx launches Enterprise Reputation API — free programmatic monitoring.
NumRep wraps all free channels into one API. Automated registration, monitoring, remediation.
