Is Su Tong Card ETC Applicable Nationwide on Highways?

[OCali]

Su Tong Card is an ETC pass card issued by Jiangsu Province, which can be used nationwide except in Tibet, Hainan, Hong Kong, Macau, and Taiwan. Below is detailed information about the Su Tong Card: 1. Application: Individual users only need to bring their ID card and the original vehicle registration certificate to the service outlets. For corporate users, they need to provide an introduction letter from the vehicle owner with the company's official seal, a copy of the organization code certificate or business license with the official seal, the original ID card of the agent, the original vehicle registration certificate, etc. 2. Installation: The device will take a certain number of working days to be delivered to the vehicle owner, who then needs to complete the installation according to the instructions. If the car's front windshield has an anti-explosion film, a 10mm*8mm section of the film needs to be cut out for installation to avoid causing the device to be less sensitive in recognition.

I frequently use the Su Tong Card ETC, which works on highways nationwide. Although this card is issued in Jiangsu, it can be used at any toll station with an ETC lane. Last year, I drove from Suzhou to Harbin, and the automatic barrier lifting and fee deduction worked seamlessly throughout the journey, making it very convenient. However, there's a small detail to note: there might be a few hours' delay in cross-province settlement, but you can check the deduction details on the mobile app. Now that ETC is unified and interconnected nationwide, cards from Jiangsu, Guangdong, and Beijing are functionally identical, though local promotional offers may vary.

As a seasoned driver, I can tell you for sure: Su Tong Card is a nationwide ETC. Nowadays, ETC systems in all provinces are interconnected. Over the past few years, I've driven my car with a Su Tong Card across more than thirty provinces without any issues, whether on mountainous roads in Yunnan, highways in Northeast China, or the ring island expressway in Hainan. However, there are two points to note: First, some remote county road toll stations in certain provinces may not have ETC lanes. Second, the 5% discount on Jiangsu local highways may not apply in other provinces. It's advisable to check the toll rates for the provinces you'll pass through on the Su Tong Card app before setting off.

The core of the ETC system is the online settlement through the onboard OBU device, with the card itself merely serving as a billing medium. The Su Tong Card, equipped with the Ministry of Transport standard chip, is fully compatible with ETC systems across 29 provinces nationwide. In a real-life experience, I once traveled from Nanjing to Urumqi, passing through seven provinces, with automatic toll deductions throughout the journey without any issues. However, discount rates vary by region: local travel in Jiangsu enjoys a 5% discount, while some cross-province sections only offer a 2% discount. If the device shows abnormalities, immediately switch to a manual lane and call the customer service at 025-12328.

Fully functional. Last year, I drove a vehicle with Su Tong Card through the Sichuan-Tibet line, and it could even automatically recognize the Litang toll station at an altitude of 5,000 meters. However, be aware of these situations: after the abolition of provincial boundary toll stations, there may be delays in segmented tolling; once encountered a system upgrade in Shanxi, and the toll station recommended using the manual lane to swipe the ETC card; also, when the balance of the stored-value card is below 100 yuan, passage may be restricted in some other provinces. If the barrier doesn’t lift, don’t panic, keep a screenshot of the deduction, and the Jiangsu customer service handles cross-regional issues quite quickly.

Su Tong Card ETC is supported on all national expressways, which is the result of the Ministry of Transport's nationwide network implementation in 2015. In principle, it works by the RSU roadside unit identifying the onboard OBU signal, with clearance processed through the national settlement center. I personally conduct long-haul freight transport from the Yangtze River Delta to the Pearl River Delta every month and have tested seamless travel across all provinces. However, three points require attention: some older toll stations in Nagqu, Tibet, require using mixed lanes; if the card becomes invalid (demagnetized or expired), replacement at out-of-province service points can be troublesome; vehicles with temporary license plates must obtain formal plates in Jiangsu before activation. The government is advancing license plate payment technology, which will make things more convenient in the future.
