He was a member of the Connecticut House of Representatives and ran unsuccessfully for the United States Congress in 1798. A staunch supporter of Thomas Jefferson, Granger was appointed as Postmaster General at the start of his term in 1801. He served in this post until 1814 when Jefferson's successor, James Madison, replaced him. He is the longest serving Postmaster General as of 2020. In 1802, he convinced Congress to pass a law making postal work white-only. He was concerned that African-Americans would see themselves as [having] a government-worker status and therefore entitled to freedom. That didn’t change until the end of the Civil War. 
After leaving Washington, D.C., Granger settled in Canandaigua, New York, where he built a homestead that would be "unrivaled in all the nation" from which he could administer the many land tracts he had acquired further to the west. Today his home is a museum. He became a member of the New York Senate and continued to be influential in politics and law including being a key figure in the Erie Canal project.
- Francis Granger (1792–1868), who married Cornelia Rutsen Van Rensselaer (1798–1823), the granddaughter of Brigadier General Robert Van Rensselaer, who was a member of the New York Provincial Congress from 1775 to 1777 and later a member of the New York State Assembly in the 1st, 2nd and 4th New York State Legislatures.
- John Albert Granger (1795–1870), who married Harriet Jackson (1804–1868), the daughter of Amasa Jackson, the first president of the Union Bank of New York, and Mary (née Phelps) Jackson, the only daughter and heiress of Oliver Phelps. Her paternal grandfather was General Michael Jackson, who commanded a regiment of minutemen in the Battle of Lexington.
Ill health forced him to retire early in 1821 and he died the next year on December 31, 1822. He was interred in Woodlawn Cemetery in Canandaigua. Granger is the namesake of Granger Township, Ohio.
