I'm selling my iPhone 6S on ebay and I have a potential buyer who is asking me to provide him/her my iPhone's IMEI. Should I do it? Is it safe? He also told me I can check it myself and just send him the result, he provided a link to a website but I don't trust the site. What can I do? Is there a website where I can check the IMEI of my iphone myself and take a screen shot, block the imei# and send it to the buyer? Thanks for the help.
