I thought delivery of these phones demanded a signature. If not where did you get a signature release form?![]()
I know you should be able to just write a note and leave it on the door or wherever visible. Just make sure you have your tracking number, shipment information, saying it's okay to leave it / where to put it, and to sign it.
I did however search online and this may come in handy and make it easier to use.
PDF link for signature release form
If the link doesn't work just search google for 'fedex signature release authorization form' and it should be the first one.
