After the war, Belcher worked as manager of his father's Oklahoma car dealership. He was admitted to the bar in 1936 and began a legal practice in Enid. In 1934, he was elected county clerk of Garfield County and served from 1934 to 1938. He also served on the Enid Board of Education and as judge of Enid's municipal court. Belcher served as executive assistant to U.S. Representative Ross Rizley during Rizley's first term in Congress and later managed several of Rizley's reelection campaigns. He served as Republican chairman of the 8th congressional district, and was also the executive secretary of the Oklahoma Republican Party. In 1950, Belcher was elected to Congress, where he served for two years as the last representative of Oklahoma's 8th congressional district before it was eliminated in congressional reapportionment. After most of the 8th's territory was merged with the Tulsa-based 1st district, Belcher ran for reelection there, and held the seat until retiring in 1973. After his home in Enid was drawn out of the district during a mid-decade redistricting in 1967, Belcher moved to Tulsa. In Congress, Belcher was a member of the Agriculture Committee and its wheat subcommittee, eventually rising to ranking Republican on that committee. In that role, he facilitated passage of legislation related to the Arkansas River Navigation System. Breaking with many of his regional colleagues, Belcher refused to sign the 1956 Southern Manifesto, and he voted in favor of the Civil Rights Acts of 1957 and 1960, as well as the 24th Amendment to the U.S. Constitution and the Voting Rights Act of 1965, but not the Civil Rights Acts of 1964 and 1968. Belcher usually had easy reelection campaigns because the Tulsa area was friendly to Republicans, but was nearly defeated in 1958 due to discontent over the Eisenhower administration's farm policy. He face another credible challenge in 1970, when former Johnson administration official James R. Jones held him to only 55 percent of the vote. With Jones priming for a rematch in 1972, Belcher announced that June that he was retiring due to age and poor health. Jones then won the seat in the subsequent election.

In addition, Tulsa is home to the Page Belcher golf course.
