It is very clear that nationwide, only Shanghai has a fixed license number range (144-146), while the national licenses issued by Shanghai cover the ranges 144-148 and 430-440, with a note indicating that the use of 146-148 and 430-440 is prohibited in Shanghai.
Furthermore, even Zhejiang, which is known for its strict regulations, can issue licenses for cross-provincial use. However, Zhejiang only issues licenses in the 144-146 frequency range.
The current regulations do not prohibit the application for nationwide licenses for UV-band equipment. This difference arises from variations in how different provincial radio management departments interpret and apply the law.
