The My Number Portal has recently released critical maintenance updates addressing various service interruptions. These essential announcements are designed to help users plan their activities accordingly, ensuring they are aware of when services will be unavailable.

Scheduled System Maintenance

Maintenance Duration:

• - From: December 31, 2200
• - To: January 2, 300

During this maintenance window, all services and functions including user registration and login will be temporarily suspended. It's imperative for users to refrain from attempting to access any features during this time as it may lead to frustration and confusion. The maintenance schedule may be subject to changes or extensions as needed, so it's advisable to stay updated.

Impact on Services

• - Health Insurance Card Registration: Users will not be able to utilize the health insurance card registration service via face recognition card readers at medical institutions or through Seven Bank ATMs during the maintenance period.
• - My Number Portal App Features: Some features associated with the My Number Portal app will also be offline. For those who have already added their card to their iPhone, functionalities outside of the app will remain available.

In order to accommodate increased use of the My Number Portal, significant structural renovations are scheduled around January 2026. Users are encouraged to check back frequently for updates concerning the expansion of services.

Important Notifications for Users

In light of connectivity issues, users may experience errors while reading their My Number Card due to external system failures. For those who received this notice earlier, services are currently back up and running. However, any application showing an “acceptance error” will need to be resubmitted.

Furthermore, enhanced security measures will soon restrict the usage of My Number Portal and its application on devices operating below iOS version 16.4, effective from May 2026. Users of outdated devices are advised to upgrade to avoid any disruptions.

For individuals requiring proofs for insurance purposes from Fukoku Shinsai Life Insurance Co., the process of obtaining necessary certificates has changed from MyPost to e-My Envelope as of now. Detailed instructions for the link-up with e-My Envelope can be found on their respective website.

Beware of phishing schemes disguised as genuine requests surrounding taxes or funds. Always verify the source before taking any actions involving personal information.

The My Number Portal’s maintenance and updates exhibit the ongoing efforts to enhance user experience and meet the rising demand. Although these adjustments may result in temporary inconveniences, the enhancements are a step towards a more efficient and secure system for managing personal identification and government services.
