After applying for a My Number Card (マイナンバーカード) in Japan, it typically takes about one to two months for the card to be ready for pick-up. However, the exact time can vary depending on the municipality and the volume of applications they are processing.

Steps in the Process:

1. Application Submission:
   • You submit your application either online or by mail using the application form you received along with your My Number notification card.
2. Processing by the Municipality:
   • Your local municipal office processes your application and prepares your My Number Card. This includes verifying your identity and printing the card.
3. Notification of Completion:
   • Once your My Number Card is ready, you will receive a postcard (受け取り通知書) from your municipal office informing you that your card is ready for pick-up.
4. Card Pick-Up:
   • You need to bring the postcard, your My Number notification card (if you have it), and identification (such as your Residence Card) to the municipal office to collect your My Number Card.
   • In some cases, you may also need to provide a 4-digit PIN that you set during the application process.
