Recently sold a pixel 2 XL on swappa & the buyer is asking about the order number for the 2 year warranty. I responded, saying the phone was a gift for Christmas & unfortunatly I dont have an order number for the phone but, for the 2 year warranty the IMEI number is more than sufficient if u need to redeem the warranty. Anyway Im a little concerned he may press for an order number. My question is what problems could arise if any for giving him the order number for the phone?
