The message came from 1 1 183.

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 the 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 "public security organ" security account ...;

It doesn't matter whether1183 is a postal code, because this number can be set at will in the virtual world. The key point is that as long as someone talks about the contents of the previous paragraph, 100% is 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.
