FILTER vs. IPQualityScore
Fraud scoring platform vs. single-purpose verification.
IPQualityScore is a broad fraud and risk-scoring engine spanning phone, email, IP, and device signals — powerful, and built for teams already running a full fraud stack. FILTER is narrower on purpose: faster to integrate, and built to return a direct connected/absent/undetermined verdict without configuring a scoring engine first.
| FILTER | IPQualityScore | |
|---|---|---|
| Scope | Phone number verification only | Fraud/risk scoring across phone, email, IP, and device |
| Setup | One endpoint, no scoring engine to configure | A configurable risk engine — powerful, more setup |
| What you get back | A direct verdict: connected, absent, or undetermined | A composite fraud score you define your own thresholds for |
| Managing a full fraud stack across many signal types | Out of scope — phone only | Yes — this is the core use case |
If you're already building or maintaining a multi-signal fraud-scoring pipeline, IPQualityScore's breadth is the right tool for that job. If what you actually need is a fast, direct answer to "is this phone number real and reachable" without standing up a scoring engine, that's the narrower problem FILTER solves.
