To those who have an account other than their own registered at public money receiving account

Q Can't I register an account at public money receiving account for someone other than myself?

Usually, when a local government provides benefits, the payment is to be made to an account in the name of the recipient, and there may be cases where it is not possible to make a payment to an account not in the name of the recipient. Therefore, if an account of a family member other than the recipient is registered, it will be necessary to confirm the account of the recipient again at the time of provision, which may delay the provision of benefits.
Therefore, although it is not a false registration, we are asking these people to change their registered account to their own account for the purpose of prompt payment of benefits. In addition, the law also requires the registration of the account of the person. For details, please refer to the public money receiving account System .

Please take this opportunity to check your registered account again, and if you have registered an account that is not yours (including an account in the name of a family member), please promptly change it to your own account.

1. Erroneous Registration in public money receiving account

Q1-1 Please tell me the details of why the erroneous registration of public money receiving account occurred.

A1-1

Local governments have been providing procedural support for Individual Number Card Point applications, and as part of this support, they have also been cooperating in public money receiving account's registration. When operating the terminals of this support desk, the person who had registered first forgot to log out of Mynaportal, and the person who registered public money receiving account next with the same terminal mistakenly registered his / her own deposit / savings account in the account of the person who had carried out the procedure before.

In addition, regarding the erroneous registrations confirmed by local governments so far, we have already made corrections to the registered accounts with the consent of the individuals, and we have not confirmed any damage such as erroneous deposits.

Q1-2 Please tell me how to check if my public money receiving account information has been registered correctly.

If you do not have a device that supports Mynaportal, you can use a family member's smartphone to confirm using your own My Number Card.

2. Errors in linking information on the health insurance card

Q2-1 Please tell me the details of the error in linking the information on the health insurance card.

A2-1

When you need to renew your insurance card due to employment, job change, retirement, or change in the scope of your dependents, the insurer of the new medical insurance will register the information of the insured person (individual) to the system (online qualification confirmation system).

For example, when the My Number of an insured person is not known, it is necessary to confirm that the name, date of birth, gender, and address match. However, there are cases where registration is made with only some information matching, or when multiple candidates (same name, date of birth, gender, etc.) are presented, linkage is made without carefully confirming the contents of each candidate. This leads to errors.

Q2-2 Please tell me how to confirm that my health insurance card information has been registered correctly.

A2-2

If you are using Mynaportal for the first time, please follow the Operation Manual for and install MynaApp on your smartphone.
After installing the app, log in to Mynaportal. Press "Health Insurance Card" in the Home tab or "use of My Number Card as a Health Insurance Certificate" in the Things to do tab. You can see your registered health insurance card information. You can also see a specific operation image below.

In addition, information can be easily confirmed, although it is only the name, by using the scanning device at the time of use of My Number Card as a Health Insurance Certificate installed at medical institutions and pharmacies. If there is a mistake in linking with a person with the same name, this alone is not sufficient for confirmation, so confirmation from the Mynaportal is recommended.

(*) If you do not have a Mynaportal compatible device, please also try the following methods. In either case, please be sure to log out after confirming.

  • Use your own My Number Card to log in with a compatible device that a family member has.

Q2-3 Where should I contact if other person's information is linked to the health insurance card?

A2-3

If information about a person other than yourself is displayed at a Mynaportal, medical facility, or pharmacy, please contact one of the following for further information.

If there is a high possibility that information other than the person's own information has been registered at any of the contact points, access to the online qualification confirmation system will be immediately suspended. After that, the insurer will confirm the facts of the matter, and if incorrect data has been registered, the registered data will be promptly corrected.

3. Incorrect linking of Individual Number Card Point

Q3-1 Please tell me the details of why the incorrect Individual Number Card Point linkage occurred.

A3-1

While local governments were providing procedural support for Individual Number Card Point applications, there was a situation where an applicant or his / her support staff interrupted the application process on the terminals of the support desk and forgot to log out. As a result, the next person who applied for the Individual Number Card Point service on the same terminal registered his / her own payment service. As a result, the applicant's My Number Card was linked to another person's cashless payment service, and points that should have been received by the applicant in the future were granted to another person.

Q3-2 Please tell me how to check if my Individual Number Card Point application is registered correctly.

A3-2

If you click "Check application status" from the top screen of the "Individual Number Card Point" app and site on your smartphone, you can check the associated payment service. Even if you do not have a compatible device for the "Individual Number Card Point" app and site, if your family members have a compatible device, they can use their own My Number Card to check.

Q3-3 If I find that a payment service has been applied for even though I do not recall applying for it, or if a payment service that I do not recognize has been registered, where should I contact?

A3-3

Please contact any of the following for further assistance.

In order to ensure a smooth response when making inquiries, please be prepared with the following information at hand: "My Key IDs," "Date and Time of Application," "Settlement Service," and "Settlement Service IDs" from the "Check the Application Status" section of the "Individual Number Card Point" app and site.

4. Convenience Store Certificate Issuance Service

Q4-1 Please tell me about incorrect issuance of convenience store certificates using My Number Card.

A4-1

The erroneous issuance of certificates was caused by inappropriate program processing, etc. of a system that each local government had commissioned to a business operator for construction. We have already completed measures such as correcting the program. At present, we are thoroughly re-inspecting the local governments that have adopted the defective product. In addition, we are conducting an overall inspection to see if similar problems exist at related business operators.

Q4-2 If I am issued a certificate with incorrect information or another person's certificate at a convenience store, who should I contact?
