If you are a MobalPay user trying to top up your MobalPay balance at a Yucho (JP Post) Bank ATM and encounter an error with the code ‘512U’ after entering your PIN, it is likely due to your categorization as a “Non-resident” by the bank. If you encounter this error, the ATM will print a statement with the error code displayed:
To rectify this issue and enable successful top-ups, you will need to change your status from “Non-resident” to “Resident.”
Changing your status to “Resident”
- Bankbook (issued by the bank where you hold your account)
- Residence card (Zairyu Card)
- Proof of employment (certificate of employment or pay slip) if you are employed
Once your residency status is successfully updated to “Resident” by the bank, you can proceed to top up your MobalPay balance at a Yucho Bank ATM without encountering the ‘512U’ error.
