Error: “That site already exists”

If a site already exists or is reserved, you will need to choose a different address for your new site.

Every site that is registered needs to use a new, unique address that hasn’t been registered before. We cannot recycle or reassign site addresses (URLs) which may appear to be abandoned. We respect bloggers’ ownership of their content and therefore will not move or delete a site without its owner’s consent — no matter how long it has been since their last update.

If you want help choosing a site address, you can also get suggestions in the signup process here:
