Mobile showing its a scam...

[mick1234]

When ordering a part for my multigrinder the supplier told me that my mobile number was showing its a SCAM number?

How is this rectified?

Where, or how, was your mobile number apparently showing as scam?

It showed up on the suppliers phone system when I phoned them to place an order.

The next question to ask is... what phone system were your suppliers using, and what is its basis for flagging particular numbers as spam?

Your supplier may not know, but I think they should be querying it with their telecoms supplier as a false positive.

I occasionally see these warnings on incoming calls & I think texts but I don't subscribe to any particular system for such filtering. I've also seen the obverse, something like "Recognised Business".

EE have rolled out "Business Caller ID" which allows for a name to be displayed in-place of a number - https://ee.co.uk/help/cyber-security/getting-started/business-name-in-caller-id and I wouldn't be surprised if a similar lookup is used somehow, in the opposite way.

Edit: Following through links from the EE business-caller-ID, goes to "Hiya" who have online forms for reporting false positives, opting in and various other combinations. Might be worth checking with your supplier whether they use a similar system with their own equivalents.
