There isn't anything particularly hard to administer about sending a one-time box to every parent who has a kid. It's not even collecting any new information--everything needed is recorded during birth registration. Even the potential for fraud is limited, because generating fraudulent SS numbers is much more lucrative than cardboard box resale, and we already have systems in place to limit that.

A county or state could easily implement this, with well-scoped resourcing requirements and little chance of cost overruns.
