Spam text messages.

If you open the conversation, you will notice a little dialogue that says the sender is not in your contact list. There will be a report message button after that.
Hope this helps

They'll just find another number to spoof and send you another text. Unfortunately, I can't remember how to block a text, mostly because I simply gave up blocking them. If there's a way to report them to Apple, I'm all ears, but I suspect it'll be as useless as blocking them.

In iOS 16, at least with some wireless carriers, Apple will be expanding the "Report junk" function to standard SMS messages. If You're using iOS 15, you can report the messages to your carrier with the number they provide for that purpose.

HTH

Go onto settings for the phone app I kind of forgot what you wrote it’s pretty self-explanatory I think like I don’t know how to do it after that but there’s a way to sorry

It sounds like the setting you're referring to is silence unknown callers, which can be enabled by going to Settings > Phone > Silence unknown callers, and toggling it on. However, to my knowledge, it only works for phone calls, not for text messages.

Hi there. I know you are reporting those messages to Verizon, but you should also call amazon if you have an account with them and tell them about the messages as well. I've gotten a few of those spam texts myself, and the first one I got, claiming to be from netflix, scared the heck out of me until I called netflix and told them about it. They said, and this goes for any messages that look fishy, not to click on the links in the messages. You can filter unknown senders in a separate list in your messages app. To do this, go to settings, then messages, then near the bottom, you should see something like filter unknown senders, turn this on. After you turn this setting on, there will be a separate thing in your messages app called unknown senders. Any messages from people not in your contacts will go here. I have this set up to block the spam texts. Just check it from time to time, as messages that are safe, like ones from your carrier, may end up there.
