Method of canceling postal ETC: 1. The owner needs to bring his ID card, driving license, etc pass, driver's license and ETC bound bank card to the postal bank outlet or ETC management department for cancellation; 2. If you have untied the ETC card and paid off the arrears, you can also call 95580 to cancel according to the voice prompt; It should be noted that if the credit card is cancelled, remember to cut off the magnetic stripe. Because it takes 45 days for a general credit card to be successfully cancelled, during this period, if you find a complete card, there is still the risk of being stolen.
