Product review
IPQualityScore fake account detection review
IPQualityScore offers a Device Fingerprint API in addition to IP, email and phone intelligence. A persistent device result can support account association and repeat-signup investigation; product access and account-linking workflow should be confirmed separately from general free lookup offers.
Key facts
- Device output
- The Device Fingerprint API example includes device_id, unique, fraud_chance, proxy/VPN/Tor context, bot-related fields and reasons. This is more than a bare IP score. Source ↗
- Collection
- Dedicated web device fingerprinting and mobile SDK paths are documented. Confirm the collection method and supported platform for the product being evaluated. Source ↗
- Commercial scope
- The site advertises 1,000 free lookups. Confirm device-product access, API limits and the price in the account or quote; a general lookup offer does not establish a device allowance. Source ↗
- Evaluation
- Inspect the actual device result, reason fields and collection behavior before comparing with general proxy or IP-scoring endpoints. Source ↗
Strengths
- Device-fingerprint result and named fraud-related outputs are publicly documented.
- Device evidence can be combined with IP, email and phone intelligence.
- API-oriented integration for application-specific account workflows.
Limitations
- A general IP lookup or free-lookups offer does not establish Device Fingerprint entitlement.
- Confirm the account associations, stored history and relationship evidence needed beyond one device response.
Who it fits
Teams selecting device, IP, email and phone-risk APIs for registration checks, with the exact feature entitlements confirmed separately.
Compare the alternatives by signup-protection scope when your team needs a different relationship output or operating model.
What the score means
The editorial score of 7.6 out of 10 places this tool in the published comparison. It reflects product fit under the same 37-criterion, six-category framework used for all ten tools.
The facts above help evaluate account linking, signal breadth, registration decisioning, legitimate-user handling, integration and access. Read every criterion and weight.
How to evaluate it
Obtain the actual Device Fingerprint response and bind it to permitted account events. Compare a repeat account with unrelated users on the same IP, and verify the product’s commercial scope.
Device API documentation and account access
Review the documented device response and obtain access to that product; confirm entitlement before testing. The route is not an anonymous live device checker.

FAQ
Is IPQS limited to IP-only fraud scores?
No. Its Device Fingerprint API documents device_id, fraud_chance and device/network evidence. Confirm the selected device product rather than judging it by an IP-only checker.
Are free lookups a free multi-accounting API?
A general lookup allowance does not prove access to device matching or account linking. Confirm the exact product, limits and account-association workflow.
What should I verify in a signup pilot?
Check the protected registration event, its account association, the returned evidence and result timing. Include legitimate shared users and confirm the exact feature and billing scope.
