What is the difference between Su E and Su U?

[EmiliaLynn]

There is no difference in usage permissions between Su E and Su U. The details are as follows: 1. Both Su U and Su E license plates indicate that the vehicle was registered at the Suzhou Vehicle Management Office, representing "Suzhou-registered" vehicles. On October 23, 2018, the Traffic Police Brigade of the Suzhou Public Security Bureau in Jiangsu Province began using the Su U issuing authority code after the Su E license plates were exhausted. 2. After the introduction of Su U, corresponding license plate numbers will be continuously added to the license plate pool in segments. Su U license plates can be processed at the Suzhou Vehicle Management Office, county and district-level vehicle management offices, industrial park and Xiangcheng vehicle management service centers, as well as all motor vehicle registration service stations citywide, uniformly adopting the "50-choose-1" selection model.

This is actually a pretty common question among us drivers. Both Su E and Su U are license plate prefixes within Jiangsu Province, with the main difference lying in their regional allocation. Su E primarily represents license plates from Nantong, meaning if you register your vehicle in Nantong, Jiangsu, your plate will start with Su E. As for Su U, it's a supplementary license plate series for Suzhou. Due to Suzhou's rapid economic development and the surge in vehicle numbers, the original Su E series became insufficient. To address this, the traffic management authorities introduced Su U. So now, new vehicles in Suzhou might carry Su U plates, while new vehicles in Nantong continue to use Su E. Don't worry about any performance differences or such—it's purely a regional identifier, similar to Beijing's Jing A or Shanghai's Hu B, aimed at facilitating vehicle source management and identification. When buying a car, there's really no need to dwell on this. Focus instead on the vehicle's condition or emission standards to avoid spending unnecessarily on fixing a bunch of issues.

I usually pay attention to automotive knowledge, especially details about license plates. There's no substantial difference between Su E and Su U; it's just different management methods for different cities in Jiangsu. Su E is typically used in Nantong City—if you live there, new vehicle registrations are generally assigned this plate. Su U was specifically designed as a supplementary license plate for Suzhou, as the Su E series had already reached saturation due to the high number of vehicles in Suzhou, requiring an additional letter to distribute the load. Simply put, the license plate code like Su E represents the region, while U is just a newly added option. For car owners, daily driving is completely unaffected—fuel consumption and maintenance are the same as with other plates. The only difference might be that city cameras may recognize whether the car is from Nantong or Suzhou when entering urban areas. When buying a car, don’t focus too much on these letters—instead, check the engine or interior to avoid unnecessary trouble. I’ve heard some out-of-town friends misunderstand, thinking that plates with E are better or more valuable. That’s purely a misconception—there’s no actual difference in value.

Speaking of this, I recall my own experience when buying a car. The license plate prefix 'Su E' is for Nantong, while 'Su U' is a supplementary code for Suzhou, with the difference lying in regional allocation. Why 'U'? The number of vehicles in Suzhou surged, and the old 'E' plates were insufficient, so the authorities added 'U' to cope. Nowadays, if you register a car in Suzhou, you might randomly get 'Su U', while Nantong still uses 'Su E'. When driving, don't worry about it—the functionality is exactly the same. A license plate is just an identification tool and doesn't affect the driving experience at all. When buying a car, you should focus more on mileage or warranty period.

Simply put, Su E represents Nantong vehicles, while Su U is specifically for new cars in Suzhou, as Suzhou has too many vehicles and ran out of original license plates. The difference is purely administrative and won't affect fuel consumption or safety. When choosing a car, don't focus on the license plate; instead, check the tire or battery condition.

I understand many people are curious about this, like a little story about the license plate system. Su E was initially used in some cities, but now it's exclusively assigned to Nantong, while Su U was specifically added for Suzhou to cope with the increase in vehicles. The difference is just a regional label, with no hidden functions. Don't be misled by the letters when buying a car; the actual performance of the car, such as engine stability, is what truly matters.
