Postal Clause
Federalist PapersThe Postal Clause grants the national legislature authority to establish post offices and post roads. In Hamilton’s account, this is a modest, expressly enumerated power whose value lies in enabling communication among the states: a practical provision that supports the intercourse on which a functioning Union depends.
Place in the Constitutional Scheme
The clause appears among powers intended to secure harmony and proper intercourse among the states. Hamilton lists it with federal authority over interstate and tribal commerce, coinage and the value of money, counterfeiting, standards of weights and measures, naturalization, bankruptcy, and the interstate recognition of public acts and judicial proceedings. In this company, the postal power is part of a larger program for making the states’ dealings more orderly and mutually intelligible.
The Confederation’s inability to regulate commerce between its members had, Hamilton argues, left the management of interstate relations incomplete. Without a common authority, states could burden trade passing through their territory, provoking resentment and disrupting public tranquillity. The Postal Clause addresses a different practical need, but belongs to the same constitutional effort: it empowers the Union to provide arrangements that cross state boundaries rather than leaving every such matter to separate jurisdictions.
Operation and Public Use
The clause authorizes the establishment of both post offices and post roads. Hamilton offers no elaborate account of their administration; instead, he stresses the power’s limited and beneficial character. A national framework for postal routes and offices can facilitate intercourse between the states, and he regards that facilitation as an appropriate object of public care.
His description is deliberately measured. The power is harmless in every view, he says, and judicious management might make it a source of great public convenience. The qualification matters: the benefit is prospective, dependent on how the authority is managed, rather than a claim that the constitutional grant guarantees any particular result.
Significance
The Postal Clause exemplifies Hamilton’s defense of a national government equipped with specific means to carry out public purposes. The provision is not presented as a sweeping or threatening authority, but as a practical instrument for overcoming the separations that make coordination difficult. Its significance rests in that conjunction of modesty and connective force: postal infrastructure can help sustain communication across state lines, while its inclusion among enumerated powers makes interstate intercourse a legitimate concern of the Union.
