Chances are that over the next few months you will be receiving phone calls or email from ‘Equifax.’ They are reaching out to verify data that you entered on their site in response to the data breach. PROVIDE NO INFORMATION. This is a scam in which people are using the data breach to steal peoples identities. Equifax will not contact you. Delete the email or hang up the phone. You can always ask them for a contact phone to call them back on because you are in the middle of something. This will most likely end up in the person disconnecting the call.
I would also suggest to people use True Caller application. This is a community based caller id service. Once someone has marked the number as spam, it will show the same once that person contacts you. At which point you can simply add the number to your blocked list.
