Register your commercial weighing and measuring device or point of sale station

Let us know if you are using a scale, meter, or bar code scanner to calculate a price charged to consumers.

What to do

If you have a device that weighs or measures quantities for customer transactions, you must register your device. Examples include scales and meters. Scales used for estimation (not a calculating a price) do not need to be registered.

1. Register your business

Make sure you register your business before you register your device. You'll need your business account number to register your device.

2. Fill out the form

If you have a point of sale station, you must register your equipment. A "point of sale station" is equipment that displays electronic price information used to charge consumers. Examples include barcode scanners and check out devices. Learn more about the required registration of point of sale devices. Learn more about device registration.

Using a weight and measurement device

Make sure you:

  • Use devices that are appropriate for the environment
  • Position devices so that customers and operators can easily read the measure or price
  • Maintain the device
  • Keep the device leveled and at zero balance before a transaction
  • Deduct the weight of the container or packaging (also known as “tare”) from the weight of the product before the transaction
  • Get approval for the application software you use to capture and process the weight information
  • Do not charge or calculate a price higher than what you advertised
