If you have downloaded your M1 Bill PDF document (such as a mobile statement, phone invoice, or utility bill) in Singapore, you have likely noticed that it is locked with a password. Financial institutions and employers protect these documents to ensure your private data remains secure during transit.
Quick Summary
- Password Format: Your account number, NRIC/FIN last 4 + letter, or mobile number.
- Example:
NRIC/FIN last 4 + letter: 1234567890 -> Password: 1234567890 - Privacy Notice: Never upload your personal bank statement to online servers. Use a local client-side tool.
How to Find this PDF in your Email (Gmail or Outlook)
Most institutions deliver these password-protected PDFs as email attachments directly to your inbox. If you are struggling to find the original message, try searching your email client (like Gmail or Microsoft Outlook) using these copy-pasteable search queries:
subject:(M1 Bill) filename:pdf
filename:pdf "M1 Bill" password
Hint: Don't forget to check the email's body text or footer disclaimer. Senders almost always print the exact formula required to open the attachment (for example, "Your password is a combination of the first 4 letters of your name...") directly in the message body.
