Are cellphones allowed at Oakmont for the U.S. Open?

Fans attending the U.S. Open at Oakmont Country Club this week might be wondering if they can use their cellphones to take photos or videos of their favorite golfers.

The answer is yes.

“We encourage people to bring their cellphones,” said Danny Sink, senior director of U.S. Open Championships.

However, only mobile devices smaller than 7 inches are permitted, according to the security policy.

Photography, video and audio recording are permitted throughout the course, but content must not be used for commercial purposes, the U.S. Open website says.

And flash photography must be disabled.

Livestreaming or shot-by-shot coverage of any player — with or without video — is not permitted at any time throughout championship week.

Attendees who need to take a phone call should move to areas away from play to answer. Device volume controls must always be set to “silent” or “vibrate” so as not to disturb the golfers.

Complimentary Wi-Fi is available throughout the grounds, including all grandstands, concession areas, merchandise pavilions and other large fan gathering areas.

Other electronics, such as computers and tablets, are not permitted on Oakmont Country Club grounds during the tournament. In addition, photo cameras, video cameras, drones, selfie sticks and handheld camera stabilizers are not permitted.

But during the tournament’s practice rounds, Monday through Wednesday, cameras and video cameras are permitted — for personal use only.

Sink encouraged fans to download the USGA app, which includes all pertinent information needed to attend the golf championship, such as where the nearest restrooms and bleachers are located.

Through the app, USGA officials are able to communicate parking and transportation information, as well as any evacuation or weather messages, he said.

“Cellphones are a great tool to get messaging out,” Sink said.
