The FBI added on Thursday that its agents also arrested 120 people suspected of involvement in human trafficking.
Most of the captured suspects have a role in advertising and selling the children to pedophiles online.
This was explained by the FBI and the National Center for Missing and Exploited Children (NCMEC) in its official statement.
The massive seven-day raid operation that ended last Sunday is the FBI's 11th operation this year to combat child sales.
Under the code name Operation Cross Country XI, the FBI went to various hotels, casinos and truck stops including exploring the corners of the city and cyberspace.
"The sad fact is that everything continues as usual, that such operations are still needed," said Staca Shehan, executive director of NCMEC's case analysis division.
"Things that have changed so far are the location and the way they sell the children," Shehan added to the Thomson Reuters Foundation.
The FBI rescued kids are on average 15 years old. But between them there was a three-month-old baby and a five-year-old girl.
Both of these children could be rescued after being offered the seller to an FBI agent disguised in Denver for $ 600.
Ironically, the person who offers the two children is a close friend of the children's family.
Similar operations were also held in Canada, the United Kingdom, Thailand, Cambodia and the Philippines. Thus the FBI statement.
