How to Find the Brother SE400’s Machine Number

Using embroidery designs from Brother’s site requires that the design be linked to the machine that you’ll use to embroider the design. This allows Brother to prepare the size and format of the design that will work properly with your machine. It also allows them to copy-protect the designs, especially the special licensed character designs.

The machine ID is used to connect the machine to the design. The machine ID is unique to your machine and is different than the machine serial number.

The machine ID for the Brother SE400 is found in a Settings page using the Control panel. Press the Settings Key on the Control Panel (circled in red in the photo below):

Select the Settings Screens

You’ll come to the first page of settings. Press the > key until you get to the page with the machine number on it.

Select the Settings Screens

    Hi Kamala,
    Thank you so much for this VERY informative site! I have it bookmarked and visit often. I downloaded embroidery designs from Embroidery Library in the PES format. I tried to open them so I could rename the different designs. None of them would open. Is this normal or do I need additional software that is able to open the PES format?

    I purchased this machine at an estate sale…it appears to have everything except the presser feet or the accessory kit. Thea Machine appears to be almost new with the instruction CD and book in good shape. Where can I order the feet or an accessory kit? I can’t wait to try it out!!!!
    Thank you so much.

      I purchased Brother feet at Also, if you go to a Brother authorized dealer, they usually have most of them in stock. You can also buy them from the Official Brother site.
