Hiscock was born in Pompey, Onondaga County, New York, September 6, 1834. He graduated from Pompey Academy and studied law with his brother L. Harris Hiscock. He was admitted to the bar in 1855 and commenced practice in Tully, Onondaga County, New York. L. Harris Hiscock and Frank Hiscock were founders of the Syracuse firm currently known as Hiscock & Barclay.

In addition to practicing law, Hiscock became involved in politics, initially as an anti-slavery Democrat, and then as a member of the Free Soil Party. Hiscock became a Republican when the party was founded in the 1850s, and served as district attorney of Onondaga County from 1860 to 1863. He was a member of the State constitutional convention in 1867, elected to fill the vacancy caused by the death of his brother. In 1872 Hiscock supported Liberal Republican nominee Horace Greeley for President, and in 1876 he was a delegate to the Republican National Convention.

He was elected as a representative to the Forty-fifth and to the four succeeding Congresses and served from March 4, 1877, to March 3, 1887. He was chairman of the House Committee on Appropriations in the (Forty-seventh Congress). He was reelected in 1886 for the term starting March 4, 1887, but resigned in order to accept the U.S. Senate seat to which he had been elected in January, 1887.

Hiscock was elected to the United States Senate by the New York State Legislature, defeating incumbent Warner Miller and Levi P. Morton in the Republican caucus and Democrat Smith M. Weed in the vote of the full legislature. Hiscock served from March 4, 1887, to March 3, 1893, and was chairman of the Committee on Organization, Conduct, and Expenditures of Executive Departments (Fifty-first and Fifty-second Congresses).

Hiscock was an unsuccessful candidate for reelection. After leaving the Senate, he resumed the practice of law in Syracuse.
