The count by the Associated Press resulted from a US-wide review of court records and announcements of arrests issued by law enforcement agencies.
The charges range from misdemeanour curfew violations in the District of Columbia to federal felonies related to the assault of law enforcement officers, theft of government property and possessing firearms and explosives.
Federal prosecutors and the FBI said they were pursing dozens more suspects who had been identified through photos and videos from the January 6 melee and tips from the public.
Those newly arrested include 56-year-old Robert Keith Packer, of Newport News, Virginia.
His mugshot appears to match the bearded man photographed at the Capitol wearing a hoodie emblazoned with “Camp Auschwitz”.
US President Donald Trump has urged his supporters not to launch new demonstrations as some are threatening, with central Washington DC resembling an armed camp ahead of the January 20 inauguration of Joe Biden.
“In light of reports of more demonstrations, I urge that there must be NO violence, NO lawbreaking and NO vandalism of any kind,” Trump said in a statement.
“That is not what I stand for, and it is not what America stands for. I call on ALL Americans to help ease tensions and calm tempers. Thank you.”
US Vice-President Mike Pence is ruling out invoking the 25th Amendment to remove President Donald Trump from power, less than a week after the president fomented the violent insurrection at the Capitol.
In a letter late on Tuesday to House Speaker Nancy Pelosi, Pence said the mechanism should not be used “as a means of punishment or usurpation” and reserved for cases of medical or mental incapacitation.
Ms Pelosi has called on Pence to secure the majority of the cabinet and vote to declare Trump unfit to serve.
As the House appears on the cusp of a bipartisan impeachment of Mr Trump, Mr Pence encouraged Congress to avoid actions to “further divide and inflame the passions of the moment” and to focus on smoothing the transition to President-elect Joe Biden’s administration.
Ms Pelosi has said if Mr Pence rejects use of the 25th Amendment, the House will move to impeach him.
Already, at least three Republicans have said they would vote for that.
