ESPY’s Phone vs IP Validation API compares the country or regional information associated with a submitted phone number against the geolocation of a submitted IP address. Designed for modern product and fraud teams, the API returns structured JSON results that help platforms identify location inconsistencies during registration, login, account recovery, and transaction review. A mismatch provides an additional risk signal to combine with identity and device checks – helping your system automatically approve trusted users, request MFA, or flag accounts for manual review.

Checking phone numbers and IP addresses in separate tools leaves gaps in fraud workflows. ESPY parses both parameters in a single request, matching carrier regional signals with live IP coordinates to surface geographic discrepancies instantly.
Query global telecom registries to identify the issuing country and regional origin tied to the submitted phone number.
Access live IP infrastructure metadata to pinpoint the country, region, and network origin of the incoming user connection.
Cross-reference location signals across both inputs to return structured pass, mismatch, or proxy indicators directly to your backend.
Integrate geographic validation logic directly into signup gates, checkout flows, and authentication backends via a lightweight RESTful endpoint.
Send a phone number and IP address in a single API call to receive instant geographic comparison data. Optimized for high-throughput backends, the API delivers fast response times without slowing down onboarding or login UX.
Flag connections originating from commercial VPNs, TOR exit nodes, residential proxies, or data center hosting IP ranges. Combining proxy detection with phone country data helps spot attempts to bypass geo-restrictions.
Stream geographic alignment signals into core application gateways, payment checkouts, and security reviews.
Need to start with partial data? The ESPY Phone vs IP Validation API can accept a Phone Number or IP Address independently via a single REST endpoint.
Clean, normalized JSON responses structured for rapid backend parsing and automated decision routing.
Combining telecom country data with IP infrastructure signals provides actionable context to refine customer-defined verification rules.
Flag differences between the issuing country of the phone number and the geographic origin of the IP address.
Uncover residential proxies, data center IP ranges, TOR exit nodes, and commercial VPNs used during registration or login.
Confirm whether submitted phone numbers belong to mobile networks, landlines, or virtual VoIP services.
Match internet service provider (ISP) and network infrastructure details across both input parameters.
Receive structured status codes that allow backend logic to apply custom pass, challenge, or manual review actions.
Receive automated Webhook notifications to update account risk statuses or trigger secondary MFA workflows in real time.
ESPY’s Data Infrastructure helps engineering and risk teams cross-reference raw phone inputs with active IP network signals. Built as a high-performance RESTful pipeline, the system delivers structured metadata to power custom onboarding and fraud mitigation workflows.

REST API
ESPY checks input variables against active telecom registries and global IP datasets to surface location discrepancies. Engineered for software architects and fraud operations leaders, the architecture combines elastic infrastructure with structured JSON outputs to stream reliable risk data into your platform.
ESPY provides the technical data layer engineered to cross-reference phone routing regions against active IP geolocations inside a unified RESTful interface. Our platform combines passive network telemetry, anonymizer detection, and dynamic risk signals to power automated trust decisioning and fraud workflows.
Traditional fraud tools check phone numbers and IP addresses in separate, isolated lookups. ESPY provides a low-latency API built for real-time geographic correlation.
Developer-First Breach Data Routing.
ESPY converts exposed account activity and breach data into structured JSON feeds designed for authentication systems, onboarding workflows, and fraud prevention platforms.
Built for high-volume, low-latency environments, ESPY provides developers with real-time breach monitoring infrastructure for modern product workflows.
Trusted by developers, system architects, and trust and safety teams worldwide.

How technical leaders integrate the ESPY Phone Intelligence API to power their registration workflows, fraud prevention, and user verification systems.
By integrating the ESPY API, platform teams can now run real-time app metadata checks across global databases, significantly reducing fake account creation and automated bot sign-ups during onboarding.
Head of Trust & Safety
Access live profile metadata and regional code registries from over 195 countries to uncover risk indicators that traditional static reverse search directories cannot catch.
Compliance Director
Risk operations use ESPY’s data layer to instantly detect unverified virtual VoIP lines and suspicious account setups. This adds a critical layer of active fraud detection to our existing user vetting suites.
Fraud Operations Manager
Built for developers. Our single-endpoint integration allows product teams to scale their user verification capabilities without adding complex system layout overhead or latency.
Director of Product Security
Verify the active profile status and history of digital footprints linked to a number. Our programmatic query allows platforms to easily separate trusted, long-standing users from newly generated malicious threats.
Lead Solutions Architect
Anti-fraud service providers leverage our phone intelligence to cross-reference mobile identifiers against open web registries, providing engineering teams with a more complete risk score.
Risk & Integrity Lead
Specialized security firms integrate our data pipeline to automate spam detection and reputation scoring, ensuring their platforms maintain clean user directories and meet regulatory compliance.
Senior Data Engineer
Everything you need to know about network correlation, privacy compliance, proxy detection, and technical integration.
It compares the country associated with a phone number with the country identified from a submitted IP address and returns geographic information together with a match status.
No. A mismatch is an additional risk signal. Travel, roaming, corporate networks and other legitimate circumstances may produce different phone and IP countries.
No. The request uses the phone number and IP address provided to the API. It does not require access to the device’s GPS location.
Yes. The result can be incorporated into onboarding logic. For example, a matched result may proceed normally, while a mismatch may trigger another verification step.
The published Phone vs. IP Validator schema documents country comparison and match status. VPN or proxy detection should not be advertised for this endpoint unless ESPY confirms that these fields are included in the production response.
Results are returned as structured JSON that can be incorporated into existing applications and risk workflows.
The same documented service also supports an email_domain_validator lookup type. However, I recommend explaining this briefly or creating a separate Email Domain Validation page. Combining both topics too heavily would weaken the main Phone vs. IP SEO focus.
Use ESPY’s Phone vs. IP Validation API to add a clear geographic consistency signal to customer onboarding, KYC, fraud prevention and account-security processes.
