You might have noticed that in some states, our Bitcoin ATMs say Stack, while in others, they say Unbank. What does that mean for you as a customer? In short: one login, full access, everywhere we operate.

Your Login Works in Both Stack and Unbank States

No matter where you signed up — Stack or Unbank — your login credentials work across both.

That means:

-If you created your account at a Stack Bitcoin ATM, you can log in to the Unbank app and use Unbank ATMs in Unbank states.

-If you signed up through the Unbank mobile app or at an Unbank ATM, you can use that same login at Stack Bitcoin ATMs and the Stack mobile app in Stack states.

There’s no need to create multiple accounts, juggle passwords, or re-verify your identity when traveling. Your account travels with you.

Why Two Different Names?

The reason is simple: state regulations. To comply with the unique licensing requirements of each state, we operate under two different brand names:

Unbank — Our brand in states where we initially launched and secured licensing under the Unbank name.

Stack — Our brand for new markets and states where we operate under the Stack name to meet evolving regulatory requirements.

This approach allows us to grow responsibly while ensuring your experience remains seamless, secure, and legally compliant.
