A proposed amendment becomes part of the Constitution as soon as it is ratified by three-fourths of the States (38 of 50 States). When the OFR verifies that it has received the required number of authenticated ratification documents, it drafts a formal proclamation for the Archivist to certify that the amendment is valid and has become part of the Constitution. This certification is published in the Federal Register and U.S. Statutes at Large and serves as official notice to the Congress and to the Nation that the amendment process has been completed.
