Office of Weights and Measures

Welcome to the Department of Licensing and Consumer Protection (DLCP) Business and Professional Licensing Administration Office of Weights and Measures.

District businesses must register all Universal Product Code (UPC) scanners, pharmaceutical balances, scales used in dialysis clinics, and commercially used weighing and measuring devices including gas pumps, produce scales, and many other devices. DLCP inspects thousands of devices twice every year to validate that the devices are properly calibrated and display accurately.

New businesses and existing businesses with new weighing/measuring devices must register the devices prior to use in any form of commerce. Registered devices must be re-inspected and renewed annually. The registration cycle runs from October 1st to September 30th. A $2,034.00 fine (per violation) will be assessed for businesses using uninspected and unregistered devices. A $250.00 late fee will be assessed for failure to renew your device(s) by the October 1st deadline.

The Office of Weights and Measures emails renewal notices to the email address provided in You must notify DLCP's Office of Weights and Measures in writing of any change in address, ownership, or contact information. Businesses that do not receive renewal notices remain responsible for renewing prior to the October 1st deadline. Certificates and device registrations are not transferable. If your business moves or adds a new device, you must register for the new location and/or the additional device.

How Can You Protect Yourself?

To be sure your purchase is measured and weighed correctly:

  • Read the package label.
  • Pay only for the product and its packaging. For example, make sure the scale weighs only the salad and its contents and does not include the weight of the container.
  • Check the unit price of the item.
  • Check your receipt to be certain the unit price aligns with the weight and/or quantity of your purchase.
  • Look for a current green and orange approval sticker and seal from the DC Office of Weights and Measures.

If you believe a merchant overcharged you, that you did not receive the quality/quantity advertised/paid for, or have another complaint, you may submit a complaint to the Office of Weights and Measures.
