The Hallmark Unique Identification (HUID) code is an essential feature for verifying the authenticity of gold jewellery in India. Introduced on July 1, 2021, the HUID code works alongside hallmark stamps, which include the Bureau of Indian Standards (BIS) logo and purity marks, to ensure that buyers receive genuine products. Prerna Khurana, Director at Khurana Jewellery House, emphasizes that while the hallmark confirms purity, the HUID allows for tracking each piece through official records. With counterfeit hallmark stamps in circulation, relying solely on hallmarking may not suffice. The HUID system provides an additional layer of security by digitally recording each code in the BIS database. Buyers can easily verify the HUID through the BIS CARE mobile app or the official BIS website, ensuring they are purchasing certified jewellery. This verification process not only protects consumers from fraud but also boosts trust in the gold market. By checking the HUID, buyers can prevent potential losses and confirm the authenticity of their gold jewellery.
