Will the phone number that can't be reached be displayed in spam messages?

It's all random numbers generated by VoIP, which is not true at all.

If you want to intercept spam messages, you can do it with software.

For example, you can install a Tencent mobile phone housekeeper.

Then use the protection monitoring-harassment interception function.

After this function is turned on, you can intercept any spam messages harassing calls for you in the future.
