Most Frequent Location API description v2
API description
The "Most Frequent Location" API verifies whether a mobile device is predominantly located in a specific area, determined by a postal code or a geographic reference. This location insight helps determine the user's likely residence based on their most visited location, providing valuable data for location-based services or identity verification.
The API consumer provides a location reference, either as geographic coordinates (latitude/longitude-based coverage zone) or a postal code, and the API returns a score between 0 and 100 indicating how frequently the device has been connected to the mobile network in that area. A score of 0 means the device has never been present in the specified location; a score of 100 means the device is almost always there.
Location accuracy depends on mobile network antenna coverage. In urban areas, where antenna density is higher, the resolution is finer; in rural areas with fewer antennas, the coverage zones are broader. The API uses aggregated network data collected over time rather than a real-time position, making it a statistical residence indicator rather than a tracking tool. By design, the API does not reveal the device's actual location: The API consumer proposes a location and only receives a frequency score, preserving user privacy. When personal data is processed, three-legged access tokens with explicit user consent are mandatory.
Use Cases
Fraud Prevention and Risk Mitigation: Financial institutions, insurance companies, and online marketplaces can use this location insight to verify the identity of users and prevent fraudulent activities. This includes ensuring compliance with regulations like AML/KYC, assessing risks, and enhancing security in peer-to-peer transactions.
Service Verification and accurate Billing: Utilities, e-commerce, and digital content delivery companies can leverage location data to verify service provisioning, ensure accurate billing, and prevent service theft. This also includes confirming that deliveries are made to the correct address, reducing discrepancies and fraud.
Compliance and Customer Screening: Real estate companies and service providers can use location insights to ensure compliance with local laws, verify tenant residency, and screen users for legal and contractual requirements, improving trust and adherence to regulations.
Location-based Services: Service providers can tailor their offerings based on the user's predominant location, enabling more relevant and personalized experiences for users in specific regions or areas.
Targeted Marketing: Marketing platforms can deliver more relevant campaigns by understanding the user's predominant location, improving engagement rates while respecting user consent requirements.
