You can't pay the electricity bill by looking at the account number in the passbook, because the passbook and the bank card are different, and the passbook is an account number, not an account number. Usually, you need to enter your electricity meter account number when you pay the electricity bill. This account number can be found on your electricity meter.

If your passbook contains information similar to the card number or serial number, it may be the bank account number, not the electricity meter account number. You can find your electricity meter account number in the following ways:

1. Check the electricity bill: If you still have your electricity bill, you can check the electricity meter account information on it.

2. Inquire through the State Grid Intelligent Interactive Website: You can log in to the State Grid Intelligent Interactive Website, verify your identity, and then inquire about your electricity meter account.

3. Inquire in the local power supply business hall: You can bring your ID card or proof of identity to the counter of the local power supply business hall to inquire.

Please note that in order to protect your personal information and account security, you should avoid storing any personal information or account information on storage devices or electronic devices (such as passbooks and mobile phones). At the same time, please make sure that the account you entered is correct when paying the electricity bill.
