What are the first digits of Shenzhen fixed telephone number?

Before the telephone number in Shenzhen rose to eight digits, prefix 2 was around Luohu Central District, prefix 3 was around Futian District, and later prefixes 2 and 3 were interspersed. The prefix 4 is Pingshan, Kwai Chung, Dapeng and Nan 'ao in the northeast of Longgang District, the prefix 5 is Cuizhu, Buxin, Reservoir and Yantian in the northeast of Luohu District, and the prefix 6 is Nanshan District.

The prefix 7 is Baoan District, and the prefix 8 is most of Longgang District. Later, the telephone number rose by eight digits, with prefixes 2, 3 and 4 preceded by 8, 5, 6, 7 and 8, and then a new number field appeared, and the numbers with prefixes 3 and 7 began to be numbered, which was quite confusing. In addition, the PHS in Shenzhen was originally a six-character, seven-digit, upgraded to a 26-character, eight-digit PHS, and later issued a eight-character, eight-digit PHS.
