Project description:
"We currently have a Chinese mobile phone number database containing approximately 30 million entries (phone numbers only, no passwords) and 5 Chinese target websites. We need to identify which of these phone numbers are registered user accounts on the said websites.
The process is as follows: Enter each phone number on the target website ， and click the "Send Verification Code" button. If the phone number is not registered on that website, a prompt stating "This phone number is not registered" will appear; if the phone number is registered, a verification code will be sent to it.
The user amount of each target website ranges from 100,000 to 500,000. It is estimated that roughly half of the phone numbers in our database can be matched as registered users, equivalent to approximately 200,000 valid registered phone [login to view URL] is preferred that the task be assigned to a Chinese national. Being able to speak Chinese will facilitate smoother communication.
已有3000万左右中国企查查手机号码库（仅手机号无密码），有5个目标网站，我需要匹配哪些手机号为注册用户。
将手机号在该网站官网输入，点击“发送验证码”。如该手机号未注册该网站，则会提示“该手机号未注册”；如已注册，则会发送验证码。目标网站用户规模为十几万到50万区间。预计可以匹配出来一半左右的手机号，也就是二十万个手机号。最好是中国人接单，会讲中文方便一些" (client-provided description)
