The CA Number (Contract Account Number or Consumer Account Number) is a unique identification number assigned by electricity distribution companies (Discoms) to every household or business connection. In India, this number is the primary key used to identify your electricity connection for billing, payments, and complaint registration.
Whether you pay your bill via Paytm, PhonePe, Google Pay, or the official electricity board website, the CA Number is the single most important detail you need. It ensures the money you pay is credited to your specific meter and account.
