Where can I find my Brother printer's serial number?

When entering your printer's serial number:
  • If your serial number consists of 9 characters, enter the complete number.
     
  • If your serial number consists of 15 characters, enter the last 9 characters. If there is a hyphen (-), enter the 9 characters that follow it.
    Example:
    For "E00000 - A1B23C456" enter "A1B23C456".
     
  • Make sure you enter upper-case letters only.

The serial number (SER.NO.) is located on a label attached on the back / bottom of the printer, or inside the printer’s label roll / tape cassette compartment.
