Spoilers for both the Fallout video games and the Prime Video series to follow.
How many vaults are there in the Fallout games?
Although the exact number may vary depending on who you ask, it’s widely accepted that there are between 118 – 122 confirmed vaults in the Fallout series canon.
Obviously, with a series constantly evolving, the number is always in flux. Depending on the direction of the story, developers can always choose to increase the number as the narrative heads in new directions. Though through four mainline games, a handful of spinoffs, and a bunch of DLC, we know for certain there are at least 118 vaults, and possibly up to 122.
As an American company, Vault-Tec’s vaults span the United States. Though there’s no telling for certain copycats in other regions didn’t establish their own vaults too. So the number could be drastically larger than what we know today, we’ll just have to wait and see if the story ever heads in a new direction.

How many vaults are there in the Fallout TV show?
We know for certain there are “over a hundred vaults spread across America” in the Fallout TV show. This was confirmed in the Season 1 finale during a private Vault-Tec meeting with top American corporations.
While there was plenty of pushback on the very concept of the vaults during this discussion, with some questioning how vault inhabitants will “survive better than animals on the surface,” Betty Pearson quickly quashed any concerns.
“How do we design our vault societies so our children have that better future?” She proposed. “I suggest we hedge our bets.”
It’s through this methodology Vault-Tec established “over a hundred” vaults, all in order to run dozens of unique experiments in hopes of producing the strongest results. AKA the most successful human society in a post-nuclear age.
For starters, Vault-Tec established “three interconnected vaults,” of which we learn plenty throughout Season 1. Though beyond that, they “[needed] more ideas.” After all, “It was the spirit of competition that made our companies great. I propose we bring that same spirit of competition to our solution.”
Each of the 100+ vaults plays out with its own rules, systems, and overall structure on “how to create the perfect conditions for humanity.
“May the best idea win,” Betty said, rather ominously.
