<prompt> Human: Hi PF, a few weeks ago two guys showed up to my house offering to redo the windows on our house. Coincidentally, we did need new windows so my mom gave them a time to come back when my dad would be home. The came back later, and my dad agreed to a time where they could give an estimate. A day later, my dad asked me to call and cancel the appointment since he was no interested anymore.So, I called and cancelled the appointment and everything was fine. Up until that point, they have been calling my house and parents cell phone almost everyday and multiple times. Today, my Dad received a letter in the mail saying he was pre-approved for the home remodeling. The letter contained information about opting out a website optoutprescreen.com or calling a number. He called that number and they asked for his SSN which he did not give and hung up.So my question is, is this a scam? Does anyone have any experience with something like this? Did they check his credit without him providing any information? They only info they have is our address, his name, and his phone number. They do not have his social or DOB. I think its just a play to get you to call back and give your information, and everything theyre saying is BS. If you want a pic of the letter please let me know! Thanks :  <response>: Financial lending companies send pre-approved letters often to garner new customers. I wouldnt worry about it too much.
