Hallmark Gold: How to Identify Purity and Verify HUID Number

• Hallmarking ensures gold purity, crucial for Indian consumers buying for festivals or investment.
• Since April 1, 2023, HUID (Hallmark Unique Identification) number is mandatory on gold jewelry.
• Three key marks to identify Hallmark gold are the BIS Logo, Purity in Carat and Fineness (e.g., 22K916), and the 6-digit alphanumeric HUID Number.
• Consumers can verify Hallmark authenticity using the 'BIS Care App' by entering the HUID number to check jeweler details and gold purity.
• Always ask for a bill, and prioritize 24-carat for investment (coins/biscuits) and 22-carat for jewelry.

Why It Matters: Always verify Hallmark gold using BIS logo, purity marks, and HUID number for guaranteed authenticity.
