"It's almost like the Super Bowl, only we're having six of them over a total of 18 days," said Maj. Richard D'Ambrosio, Area IV commander for the Pennsylvania State Police.
Police Commissioner Kevin Bethel said the department is preparing for a deployment similar in scale to the city's largest NFL events.
"The biggest deployment we've ever done down there is the NFC game, right? And when we won the playoffs in the NFC, that's how big of a blueprint we'll have," he said.
The World Cup matches, scheduled between June 14 and July 4, will bring unique challenges, officials said.
Special Agent in Charge Wayne Jacobs of the FBI's Philadelphia Field Office pointed to "the scale of the events and just the compressed nature of the timeline."
Planning has been underway since Philadelphia was selected as a host city in 2022.

Agencies including the FBI, Homeland Security, Pennsylvania State Police and Philadelphia Police are coordinating on counterterrorism, human trafficking prevention, traffic management and crowd control.
Police deployments will vary by match depending on the expected fan base.
The largest operation is expected on July 4, when a World Cup match coincides with celebrations on the Benjamin Franklin Parkway marking America's 250th birthday.
"We still have a city to run. July 4th weekend is one of the most violent periods across the nation," Bethel said.
Bethel said the timing of the July 4 match may help ease pressure on police resources.
"The good part is, the soccer game is at five, and so it should end prior to the late activity. That enables us to make some movement of personnel, if necessary, to be able to pull them down," he said.
All host cities will share information through a national coordination hub, including updates on any potential threats.
Jacobs said the goal is "just to make sure that we're fully informed about security posture, any changes, and putting ourselves in position to react, respond in the event of something happening."
Questions have circulated about whether tailgating will be allowed at World Cup events.
FIFA has said the decision is up to host cities, and Philadelphia officials have not yet determined whether a formal policy will be put in place.
"Tailgating, I don't know. You can ban it all you want. They're still gonna do it," Bethel said. "We'll see how that goes as we go through the process. I mean, I'm careful. You know, the more you tell people you can't, the more they want to do it."

With visitors expected from around the world, police are also preparing for language barriers.
The Philadelphia Police Department has adopted new body-worn cameras capable of translating 120 languages voice-to-voice in real time.
While much of the attention will center on Lincoln Financial Field, police say there will also be a significant presence at Lemon Hill in Fairmount Park, where the FIFA Fan Festival will run for all 39 days of the tournament.
The area will be fenced off, and a private security firm will screen visitors entering the park.
