API Description

Nowadays the mobile phone is the principal device used to access internet, therefore any data linked to it is very valuable to identify the user behind. This is why mobile identity has become so relevant in the last years to be able to verify that internet users are who they say they are. The ability to increase the level of trust of the mobile identity could help significantly our customers to make more precise decisions and reduce any potential fraud.

This is exactly the aim of the Know Your Customer Tenure API, it establishes a level of trust against the mobile identity by verifying the length of tenure of the user who is bound to a phone number with their current mobile operator; meaning by tenure the period of time a phone number has been associated to the specific user in their current mobile operator.

The Know Your Customer Tenure API checks whether the lifetime tenure of a given phone number is longer than an input date provided by the customer.

The Know Your Customer Tenure API provides a simple and efficient method to determine whether a phone number has been in use for a significant period, offering a strong indicator of user stability and reducing reliance on self-reported identity data.

Use Cases

  • API customers can validate the level of trust of a user whenever their phone number is used as an identifier for their online activities e.g. onboardings, transactions, etc.

  • Support to mobile phone authenticators like Number Verification API or One Time Password SMS API, because it gives higher level of trust to authenticate a phone number with large tenure than with low.

  • Support of Know Your Customer Match API onboardings, because it gives higher level of trust to validate the KYC identity of a user with large tenure than with low.

  • Strengthens fraud detection processes by identifying recently activated phone numbers that may indicate fraudulent activity.

  • Enhances identity verification in digital platforms by offering an additional trust factor based on phone number tenure.

  • Supports financial services in evaluating user credibility, reducing the likelihood of identity fraud in lending, banking, and payment transactions.

Benefits

  • API customers can quickly and easily establish a level of trust of their users who are associated with a specific phone number, based on how long they have been associated with that number in a specific Mobile Network Operator (MNO).

  • Increases the level of trust of the mobile identity products.

  • Reduces the risk of identity theft and fraud.
