They're fraternal twins, not identical.

How can you tell the difference between Grayson and Ethan?

If you take a look at both guys, you'll notice that Grayson has a birthmark on the bottom of his chin while his brother does not. Similarly, Ethan has a birthmark right next to his eye. It might be a minuscule detail, but it's a sure-fire way to tell the brothers apart!

Who is the older twin Grayson or Ethan?

Born in 1999 and hailing from New Jersey, fraternal twins Ethan (20 minutes older) and Grayson Dolan first began posting videos online in 2013. They quickly attracted a large following with their often humorous posts about their lives, as well as pranks, skits, and challenges.
