To sign up for "Informed Delivery" go This is interesting as I have had "informed delivery" for about as long as it has existed, yet when I did a mail forwarding order they charged my credit card $1.05 which they said was to verify my identity. Could be that is what everyone will have happen? 4 hours ago, Al F said: There is no requirement to have a mobile phone, that I know of. I have informed delivery notification come to my computer via email. The same with my informed delivery. I may have listed a phone number as I signed up long enough ago that I don't recall but my informing notice is via email. 19 minutes ago, LindaH said: I just tried to sign up this morning, but I keep getting a 405 error when I try to sign in to my account. I just signed into mine as a test and it was successful. Might be worth another try.
