How to Identify your Square Register Model
To identify the model of your Square Register, you will need to locate either your Square Register or Customer Display serial number. There are two ways to find this:
Go into Settings > Hardware > General > About Register on your Square Register.
Alternatively, the Customer Display serial number can also be found on the underside of the Customer Display. You will need to disconnect the display from the Square Register to view this. The Square Register serial number can be found underneath the Customer Display near the hinge, facing the customer, which you may need to place the unit on its back or lift the screen to view.
|Square Register Model||Customer Display Serial Number||Register Serial Number|
|Square Register CS133||xxxCS133xxxxxxxxx||xxxCS134xxxxxxxxx|
|Square Register CS078||xxxCS078xxxxxxxxx||xxxCS079xxxxxxxxx|
