According to Article VII, the Constitution was required to be ratified by 9 of the 13 states before it went into effect. All 13 eventually ratified, the last two being North Carolina (1789) and Rhode island (1790). In June 1788, New Hampshire fulfilled the requirement for ratification set forth in Article VII by becoming the ninth state to approve.

The Constitution didn't become law until it formally replaced the Articles of Confederation on March 4, 1789, however.
