Device Serial Numbers 

Serial numbers are essential for identifying, troubleshooting, and managing warranties for your Toast devices. They help identify specific devices in your setup, validate warranty eligibility for replacements or repairs, and assist technical support when troubleshooting device issues.

Note if the serial number sticker is fallen off, you can always find it in the device Status page in the Toast app.

  1. Open the Toast App: Log in to the Toast POS app on the device you are using. 
     
  2. Access the Menu: Tap the overflow icon, represented by a carrot (▼) or three vertical dots (⋮), in the top-right corner of the screen. 
     
  3. Select "Device Status": From the drop-down menu, select the "Device Status" option. 
     
  4. Navigate to the "Device" Tab: In the Device Status dialog box that appears, look for a "Device" tab or a left-hand rail menu and select it.
