Setup a Mailbox

Likely works international - USPS only in the US - Letters and Small packages only

No Fake ID needed

Find a trailer park where everyone sets up their own box on the road. Simply add a box to the end with a non-existant lot number shortly before you expect the letter. When using any of the methods above, all the rules of staying secure apply. Never do it in your home town. No fingerprints. No trace. When using a fake ID, use a picture that kinda looks like you, but not close enough that it could be used to identify you. Some methods require the ID to be scanned.
