Cell phone number to search for.

The original understanding of where the cell phone number belongs is the privacy border.

When we get a call from a stranger, the “Gangdong Shenzhen” or “frauded harassment” are often automatically displayed on the mobile screen. This technique of instantaneous determination of the location of a mobile phone number is a search based on the location of the mobile phone number. This tool provides you with a lightweight online query interface.

1. How are mobile phone numbers assigned?

The 11-bit mobile phone number in mainland China is not randomly generated, but has a strict structural plan (i.e. HLR). Attribution location registerer code:

• Top 3 (network identification number): Used to distinguish between different basic telecommunications operators. For example, 139 for movement, 130 for connectivity, 133 for telecommunications, 192 for new On behalf of China's wide power.
• 4th to 7th bits (area code): This is the core 4-digit (HLR code) of the place where the decision is made. The Ministry of Industry and Communications will take this 4-year-old. The figures are distributed to the local and municipal exchanges in each province and city. So just know the first seven of a number. It's a bit, and it's 100% sure where it's opened.
• After 4 bits (user number): is the specific random user number.

2. Would searching for the place of belonging reveal the owner ' s privacy?

Absolutely not. Information on the place of attribution is a fully open allocation rule for the sector number segment and is the basis for the web route. This tool only resolves the first seven of the numbers The only thing it knows about this is where it was bought and opened. The real name, ID number or current real-time GPS location of the owner of the machine is never available. So you can check any number without fear of intrusion into the privacy of others.

3. Will the place of belonging after the transfer of the number of the vehicle change?

This is a concern for many. The answer is: The place of belonging will not change. 。 Even if users had “portable networks” (e.g. from mobile to telecommunications) and even if people had moved across provinces, the physical location of the number would still belong to the province or city where the account was opened. Current attribution searches are mainly used to prevent telecommunications fraud (e.g. alerting to unidentified calls in remote or offshore areas) and to verify business registers.
