PDF [523KB] / Japanese

TOKYO -October 30, 2025 - Internet Initiative Japan Inc. (TSE Prime: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced changes to the procedures for verifying customer identity when signing up for its personal MVNO service IIJmio . Starting in mid-January 2026, verification will be available via the Japanese Public Key Infrastructure (JPKI) service (*1) using the customer's Individual Number ("My Number") card, and by matching the digital data in the IC chip on ID cards with the facial image.(*2) A new smartphone application, "ID verification for IIJmio" will also be provided to facilitate the procedures.

These changes are being instituted to comply with FY2026 revisions to the "Act on Identity Confirmation, etc. Performed by Mobile Voice Communications Carriers for their Subscribers, etc. and Prevention of Wrongful Use of Mobile Voice Communications Services." In response to the revisions, the current method for verifying identity when newly signing up for IIJmio, of uploading identification documents, will be discontinued and replaced by more secure procedures using the JPKI service or by reading the IC chip on ID cards and matching with facial images. The changes are intended to prevent fraud such as third-party identity theft or document falsification.
The smartphone application "ID verification for IIJmio" will be made available for reading the IC chip of My Number cards or other identification cards. This application adopts the LIQUID eKYC platform, provided by Liquid, Inc., for identity verification.

• (*1)JPKI (Japanese Public Key Infrastructure): An identity verification service, based on public key encryption, using the digital certificate embedded in a My Number card IC chip for online verification of the user or for preventing falsification of contracts or other documents.
• (*2)Matching the digital data in the IC chip on ID cards with the facial image: Online identity verification by first reading an IC chip in a driver's license or other forms of ID, then capturing the customer's appearance (face) and matching it with the facial image data stored on the IC chip.
