FAQs on Docker accounts

What is a Docker ID?

A Docker ID is a username for your Docker account that lets you access Docker products. To create a Docker ID you need one of the following:

  • An email address
  • A social account
  • A GitHub account

Your Docker ID must be between 4 and 30 characters long, and can only contain numbers and lowercase letters. You can't use any special characters or spaces.

For more information, see Create a Docker ID.

Can I change my Docker ID?

No. You can't change your Docker ID once it's created. If you need a different Docker ID, you must create a new Docker account with a new Docker ID.

Docker IDs can't be reused after deactivation.

What if my Docker ID is taken?

All Docker IDs are first-come, first-served except for companies that have a U.S. Trademark on a username.

If you have a trademark for your namespace, Docker Support can retrieve the Docker ID for you.

What's an organization name or namespace?

The organization name, sometimes referred to as the organization namespace or the organization ID, is the unique identifier of a Docker organization. The organization name can't be the same as an existing Docker ID.
