Swifties have cracked the code. No, they haven't guessed the date for Taylor Swift's new album release or the location of her next date with Travis Kelce. Instead, they've uncovered a secret code that can get you free Dunkin'!

Rumblings of a secret code for Dunkin' iced coffee, courtesy of Taylor, first surfaced on social media late last week.

"Entering '123LETSGO' in the Dunkin app gets you a free iced coffee," @TheSwiftSociety shared on X (formerly Twitter).

The promo code is a reference to the "1-2-3 let’s go b***h" rallying cry that Swift says at the start of her performance of the song "Delicate" on the Eras Tour.

The tweet from @TheSwiftSociety has gone on to receive over 25,000 likes, and numerous fans have confirmed that they were in fact able to get a free iced coffee from Dunkin' using the code 123LETSGO.

"Literally just got mine in my eras tour hoodie. Thank you Taylor," one user tweeted.

"How does she do that??? How does she know exactly how to drive all of us Crazy over her? Most impressive," another person added.

The iced coffee freebie has also made its way to TikTok, where fans confirmed the validity of the code.

"I don't trust anyone that says anything on the internet so I did it to prove them wrong and it worked...It gives you a free iced coffee. Dunkin's version," said TikTok user @ekelleydesign.

To echo the sentiments of one fan in particular, "Taylor for president."
