Significance of the A113 code in animation films

The “A113” code holds special significance in the world of animation, particularly among animators associated with Pixar Animation Studios and Disney. It is a recurring Easter egg or inside joke that appears in numerous animated films, television shows, and other media created by Pixar and other animation studios. Here’s why it’s significant:


“A113” refers to a classroom number at the California Institute of the Arts (CalArts), a renowned school for animation and film studies. Many of the key figures in animation, including several Pixar and Disney animators, attended CalArts.


  1. Homage to Roots: The use of “A113” is a tribute to the animators’ alma mater and serves as a nod to their shared educational background.
  2. Sense of Community: It fosters a sense of camaraderie and connection among animators who share this common experience of studying at CalArts.

Examples in Films:

  1. Toy Story (1995): License plate on Andy’s mom’s car.
  2. Finding Nemo (2003): Model number on the camera used by the diver who captures Nemo.
  3. The Incredibles (2004): Room number for Syndrome’s control room on his private island.
  4. Ratatouille (2007): Legal document number on the letter sent to Linguini regarding his inheritance.
  5. Up (2009): Courtroom number during Carl Fredricksen’s trial.

Usage Beyond Pixar:

  1. The Simpsons: “A113” has appeared in several episodes of the long-running animated series, created by Matt Groening, who also attended CalArts.
  2. Other Animation Studios: The code has been referenced in various non-Pixar animated films and shows, reflecting the influence and interconnectedness of the animation community.

Inside Joke:

For animators and those familiar with its significance, “A113” serves as a playful Easter egg to spot in each film, adding an element of fun and discovery for attentive viewers.

Overall, while “A113” may seem like a random sequence of characters to many, for those in the animation industry and fans of animated films, it holds a deeper meaning as a symbol of shared experiences and a reminder of the roots of many talented animators.
