On my USPS account I was able to get a package redirected to the new house I'm hoping to get. I had to pay almost $20.00 but it will send to my new address, wish it were for free though! If you go to manage your mail on top I was able to ask for no signature required also. It also has
If your package doesn’t fit in your mail box and you won’t be home to receive it, you can provide delivery instructions online and authorize your carrier to leave it in a specified location. Just track your package and select “Delivery Instructions”. You can request that your package be left with a neighbor or held at a Post Office™ for pickup. For the cost of additional postage, you can have your package sent to a different domestic address. You can also change your shipping service option, upgrading to Priority Mail Express® or Priority Mail®, as well as add insurance and extra services.**
i can't find anything else about electronic signatures, but I was able to change it to no signature required!
hope that helps but like I said it cost me almost $20.00
We received your Package Intercept Request.
The total price is an estimate based on the weight, dimensions, and mail class of your package. The actual postage is determined after your package arrives at your local Post Office™ and is weighed and rated.
USPS does not charge your credit card until the package's actual postage is determined. USPS only charges the estimated amount or less.
If the actual postage is more than the estimated postage, USPS will notify you by email or text and the entire actual postage price must be paid with cash, check, or Money Order when your package arrives.
Example: If your estimated postage is $11.50 but the actual postage is $13.50, you must pay the carrier $13.50 with cash, check or Money Order when your package arrives.
hope this can help a little!
