My mobile - not a published number & used only for contact with a handful of callers - was called by 507 993 0041.
No caller ID. I did not recognize the area code or the number, so did not answer.
I am glad that there are web sites such as this. They help us find out if the callers are likely to be spammers, scammers, or other unwanted nuisances.
If you get a call, do as I did. Check on the number, and then post a report so others will be helped.
My number which is in the donotcall registry and not a published number was called by 1 507 203 6993.
No caller id. I did not recognize the number so did not answer. Went to my voicemail, no messages left. Thank you to all those who posted. When you get a call from these random numbers, search for the number and add your post, so you can help others identify spammers, scammers etc.
