South Korea Begins Trial Requiring Face Scans to Register New Mobile Numbers

Officials say scans only match IDs in real time without storing biometric data.

Overview

  • The trial started Tuesday and requires applicants to verify identity by scanning their face with the PASS app when obtaining a new number through SK Telecom, KT, LG Uplus or an MVNO, whether online or at retail.
  • Authorities plan an official nationwide launch in March following the pilot with the three main carriers and low-cost operators.
  • Regulators intend to revise the law to make carriers warn users about risks tied to illegally registered phones and to tighten oversight of retailers’ new subscriptions.
  • Officials target phone-based scams enabled by fraudulent registrations, citing ministry data that MVNO channels accounted for 92% of counterfeit-phone cases in 2024.
  • The move follows a year of major breaches, including SK Telecom’s exposure of data on 23 million customers that drew heavy fines and an order to compensate affected users.
