You can't be sure whether it's a fraud or not just by a phone number, but all kinds of strange calls asking you to remit money are generally fraudulent calls.

When you receive a phone call suspected of fraud, don't do anything, just hang up.

In case of careless operation or personal information disclosure, it is necessary to promptly notify the bank to freeze account deposits, change passwords, and inform family and friends of their information disclosure to prevent being deceived.
