That is an average of 38.9 requests per day to become a police recruit compared with an average of 11.3 submissions a day for 12 days in June.
In recent months, the police department has had to cancel academy classes because there were not enough applicants.
Potential officers in the north Texas region have often opted for departments in fast-growing cities surrounding Dallas where starting pay is typically higher than in Dallas.
Dallas Police Chief David Brown put out the call for new recruits at a news conference last week where he spoke of the deaths of five officers and the actions of others to save lives at a rally in the city in the incident that marked the deadliest day for U.S. law enforcement since the Sept. 11, 2001, attacks on the United States.
“We are hiring. Get out of that protest line and put an application in,” Brown said.
U.S. police forces have been the target of protests following the fatal shootings of black men by patrolmen in Baton Rouge, Louisiana, and outside St. Paul, Minnesota, that were caught on video.
Further, the series of high-profile police killings of black men in the past two years have sparked the most intense debate on race and justice in America in years.
“It’s a shame it took a tragedy to get people to apply, but glad to see so many people willing to serve their community,” Dallas resident Ben Shaw wrote on the department’s Facebook page on Friday.
