The Delhi government's order for mandatory submission of permanent account number (PAN) and bank account number (BAN) for grant of permit for transport vehicles (both passenger and goods carriers) will set a right example for other states. Other states may replicate the measure to curb transport operators, who have been evading tax for long. Indian Foundation for Transport Research and Training has urged the finance minister and road transport and highway minister to expand the ambit of mandatory submission of PAN and BAN to all states and extension of the network to passenger cars also.
