Overview of Eligibility Information Notice and Qualification Certificate

Differences Between Eligibility Information Notice and Qualification Certificate

2. Eligibility Information Notice

Issuance of Eligibility Information Notice

• For all employees who join the company after the abolition date of health insurance cards (new issuance and reissuance) and all individuals newly certified as dependents of the Health Insurance Society, the Health Insurance Society will complete a procedure called Online Eligibility Verification that enables medical institution visits.
• After the above procedure is completed, an Eligibility Information Notice will be issued and delivered via the company. Once you receive it, you can visit medical institutions using your My Number health insurance card.
  • * If there are problems with the application form details or any missing documents, data registration for Online Eligibility Verification cannot be completed, and issuance of the Eligibility Information Notice will be delayed. For this reason, please ensure that documents submitted to the Health Insurance Society include accurate personal identification numbers (My Number) and the name (kanji and kana), date of birth, gender, and address listed on your resident registration or My Number card.

Using the Eligibility Information Notice

• You can confirm your health insurance code and number, which are needed for various applications to the Health Insurance Society and inquiries.
• When individuals with My Number health insurance cards visit medical institutions, if the medical institution does not have a card reader for My Number cards or if the card reader is not functioning properly, you can receive insurance-covered treatment by presenting the Eligibility Information Notice together with your My Number health insurance card.
  • * You cannot visit medical institutions with only the Eligibility Information Notice.

If You Lose Your Eligibility Information Notice

• If you wish to have your Eligibility Information Notice reissued, please submit a Health Insurance Eligibility Certificate (Re)issuance Application Form. However, if you can access the Medical Insurance Eligibility Information Screen on Mynaportal, this application is generally not required, as the screen can be used as a substitute.

3. Qualification Certificate

Issuance of Qualification Certificate

• For those who have not obtained a My Number Card or have not registered their My Number Card as a health insurance card (My Number health insurance card), the Health Insurance Society will verify their status and issue a Qualification Certificate to eligible individuals, which will be delivered through the company.
• The Qualification Certificate will be valid until December 1, 2029, so please switch to a My Number health insurance card in accordance with national policy before that date.

Using the Qualification Certificate

• Those who do not have a My Number Card or who have not registered their My Number Card as a health insurance card (My Number health insurance card) can present the Eligibility Confirmation Certificate instead of a My Number health insurance card when visiting medical institutions to receive insured medical treatment.

If You Lose Your Qualification Certificate

• If you lose your Qualification Certificate, please submit a lost property report at a police box or police station.
• If you wish to have the Qualification Certificate reissued, please submit a Health Insurance Eligibility Certificate (Re)issuance Application Form. Please note that a reissuance fee of 2,000 yen will be required, so keep the certificate safe and be careful when using it to avoid losing it.

Returning the Qualification Certificate

• If you lose eligibility before the expiration date of the Qualification Certificate (December 1, 2029) due to leaving the company or a dependent being removed from health insurance coverage, please return the Qualification Certificate to the company.

4. Conventional Health Insurance Cards

If You Lose Your Conventional Health Insurance Card

• If you lose your health insurance card after December 2, 2024, please submit a lost property report at a police box or police station, then submit a Declaration of Lost Insurance Card.
• Conventional health insurance cards will not be reissued, so please use your My Number health insurance card (or Qualification Certificate).

Returning Your Conventional Health Insurance Card

• If you lose eligibility before the end of the transitional period for health insurance card use (December 1, 2025) due to leaving the company or a dependent being removed from health insurance coverage, please return the health insurance card to the company.
• After the end of the transitional period, it is not necessary to return the health insurance card; please dispose of it yourself.

• If the validity period expires, you will no longer be able to log in to Mynaportal, and the card can no longer be used for electronic applications such as e-Tax, convenience store certificate issuance, or as a health insurance card. Please complete renewal procedures at your local municipal office. For details, please contact your municipal office.

If You Lose Your My Number Card

• Contact the Individual Number Card Call Center (0120-95-0178) to perform temporary suspension procedures. If you lose your My Number Card outdoors, please submit a lost property report at your nearest police box or police station before applying for reissuance. When applying for reissuance, you will need the police station name, telephone number, officer's name, and lost property report acceptance number, so please make note of these in advance.
• If your Individual Number changes when your My Number Card is reissued, please promptly notify your company and the Health Insurance Society.
