Barron Trump debuted a new pragmatic look, sporting a polo shirt and khakis as he left the campus of NYU Tuesday, as its revealed security have prevented him from giving his phone number to girls. 

President Donald Trump's youngest son is often seen looking the part of a future businessman in formalwear and slicked back hair, bearing a striking resemblance to his father.

On Tuesday, however, DailyMail.com's exclusive photos show Barron in New York City in a white polo shirt, khakis and a belt as he dragged his backpack away from campus.

In addition, he'd gone with a rougher look with his hair, wearing it more naturally without much combing or hair product. 

At least one member of Barron's security detail was seen shadowing the president's son.

Donald and Melania's only child has to find creative ways to meet people, including campus co-eds, as he navigates life at one of the country's most prestigious universities. 

It comes as no surprise that the family members of any sitting president of the U.S. take extra precautions to ensure their safety.

And for Barron Trump - Donald's youngest son - this means avoiding giving anyone his phone number.

Instead, it seems that the 19-year-old typically communicates with his friends via different gaming platforms.

This was previously limited to Discord - but it seems that the teen now also utilizes Xbox as a social outlet.

'He has added it to his repertoire,' a source told Page Six. 'It's his communication platform of choice.'

Barron, who is studying finance at New York University Stern School of Business, is constantly guarded by the Secret Service on campus at all times - thus limiting his opportunities to socialize face-to-face.

He is also forbidden from giving out his number to avoid it leaking further afield.

The source told the outlet that it 'creates more trouble than it's worth.' 

'If people get the number, they would give it out and then a million people would be calling non stop. 

'You'd have to change the number constantly and it'd become a merry-go-round,' they added.

Barron, who recently graduated from Florida's Oxbridge Academy, instead gives out his gaming usernames as a 'work around.'

The Trump scion believes this to be a safer form of communication thanks to the sanctity 'gamer bro culture.'

This isn't the first time that Barron has been in the spotlight for his use of technology.

In a recent conversation with Laura Ingraham, President Trump mentioned that his son had 'an unbelievable aptitude in technology.'

'I turn off his laptop, I said, "Oh good" and I go back five minutes later, he's got his laptop. I said, "How'd you do that?"' Trump said. 

Apparently his son replied, 'None of your business, Dad,' the 78-year-old revealed.

Trump went on to say that even out of politics or business, Barron's strengths lie in technology. 

In other instances, Trump has said that Barron is 'pretty popular,' even more so than his other sons. 

Melania even said that Barron is the reason Trump brought in a lot of young voters. 

'He was very vocal, and he gave an advice to his father, and was incredible how he brought in a success because he knew exactly who his father needs to contact and to talk to,' Melania said.
