1 1 183 send a message?

One thing you should know first, you won't be cheated whether you go or not:

In fact, no entity is involved in posing as a courier fraud. You will only call which number you want to check first, and then say that your account has contraband, you are suspected of committing a crime, your identity has been fraudulently used, your bank card is unsafe, and you need to transfer the funds to the security account of the "public security organ" ...;

It doesn't matter whether1183 is a postal code, because this number can be set virtually at will. The key point is that as long as someone talks about the content of the previous paragraph, it is 100% regarded as fraud, and there can be no exceptions. In addition, if you go to the post office to pick up something on the spot, you won't be cheated as long as you don't have an IQ of 0.
