1. First, you can ask the other party to provide their own alarm number or name, and ask the full name and address of their local police station. Then, you can look up the contact information of the police station through the internet or the phone book, and compare and verify whether the information provided by the other party is consistent with the real situation.
2. If in doubt, you can call the local police station directly to confirm whether there is such a verification requirement. Be sure to call the police station you inquire about, not the phone provided by the other party.
3. When receiving a similar call, try to keep calm, ask the other party what the specific verification items are, and ask the other party to provide supporting documents or relevant evidence. You can ask the other party to send the supporting documents to your email address for your further verification.
If you still doubt the authenticity of the phone, you can ask for help. For example, you can seek advice and suggestions from professionals, lawyers or consulting institutions who know the relevant fields around you.
Please remember to be cautious about the provision of personal information and beware of fraud. If in doubt, it is most important to protect your rights and interests and safety.
