AD code is a 14-digit numerical code provided by your bank branch where you hold your business/current account. AD code is a mandatory document when you export or import goods to other countries. It is required during customs clearance of the goods without which shipping bill number will not be generated. AD code indicates that the foreign currency transactions in your bank account are the result of trading goods. The AD code is printed on your bank’s letterhead, in a format prescribed by the Director General of Foreign Trade (“DGFT”). Your bank must deal in, or be an authorized dealer of, foreign currency, in order to be able to grant an AD code.
