How To Verify Esn With Att?

Im selling a phone on ebay, how do i verify that the esn is clean?

• Answer:

  what do you mean verify the esn is clean? If your using it and it's working then it must be clean..I mean working, what do you mean clean? when you sell a phone on ebay that's verizon and uses esn you just give them that esn to activate unless they cannot use the phone at all...you can try and call verizon and verify but if its working for you know then you know it works..it should change from what the sticker/code is ...it doesn't ever change to another one so i think your pretty much A ok don't worry about unless the buyers says so...and give a refund
