Where is the mobile phone number beginning with 183?

The first three digits of the mobile phone number can only confirm that this mobile phone number belongs to China Mobile, and it is impossible to know the attribution of the number.

The mobile phone number used in China is 1 1 digit. The mobile phone number can be divided into three segments, all of which have different coding meanings: the first three digits are the network identification number, the fourth-seventh digits are the area code (HLR home location register), and the eighth-1 1 digits are the user number (randomly assigned).

Since 0: 00 on July 22nd, 1999, the number of digital mobile phones in China has increased to 1 1. There must be at least a few firsts in this promotion: China's first national telephone number upgrade, China's first mobile phone upgrade, and the largest number upgrade in the world. China will be the first country with 1 1 digit since the establishment of ITU.
