how to stop spoofing?

I have been getting "return" calls from people who say I called them.  Apparently, someone is using my phone number to spoof the number on the caller id screen.   This is annoying. 

Since landline and cell phones both have unique hardware identifiers, I would seem fairly straightforward for phone service providers to block outgoing calls where the caller id is not registered with the hardware unique id.  Business that want to display a name instead of a number for caller id could register that name through the service provider.  

It sounds too simple to work.   Comments?

We're here to address your call spoofing concerns, @AGForumuser01.

 

When it comes to number spoofing, there's no action we can currently take on our end to avoid it. Your best bet is to ignore calls from unknown numbers that you receive as a result of spoofing, and to block any numbers that continue to call.

 

Please don't hesitate to reach back out if you have any other questions or concerns, and thanks for reaching out on the AT&T Community Forums.

Spoofed numbers are randomly generated by a computer.  I recently got one that showed the CID of a well known company that sells luxurious Oriental rugs.  I KNEW it wasn't them.  No number is immune from spoofing.

As stated, do not answer calls from unknown numbers.

I think you missed my point  and I wasn't clear.  I already ignore these calls, don't respond, and setup blocking where applicable.  I also realize that it is beyond the scope of any one company to block these calls. 

My point is that if we can prevalidate financial transactions with credit and debit cards, we should be able to prevalidate a phone call.  The technology to do this exists.  Phones and call infrastructure lready have the hardware.  Companies already track this information for billing purposes. 

To implement this and would take  a cooperative effort among many companies to implement.   It shouldn't matter how a call is generated (computer, cell, landline, pbx), I believe you can technically do it.

Whether or not it makes sense to do it is a separate issue. .

While it may sound easy it's really not. Your CC example is not really comparable since you're only dealing with one place to verify and just look at all the CC fraud, so how much worse would it be if you had to rely on 50 verification centers that depended on each other's data bases? In theory you could verify the CID leaving a switch actually existed in that switch, except that in most cases the spoofed number aren't leaving a US switch they come from overseas in that wonderful untraceable cloud. There is some data base verification being used now on cellular networks and digital systems it's called Stir-Shaken, but it's far from perfect. So, until then all we can do is wait it out. My daughter had the same thing happen to her, she put on her voicemail that her number was spoofed and asked the caller to block it and report it. The calls slowed and finally stopped after about three weeks so the person or people spoofing her number moved on to another number to spoof. Her number still comes up as possible spam when she calls someone, don't know how long it will take for that to go away.
