First, please sure make you haven’t already created a Hostelworld account using your ISIC details.

Each ISIC number can only have one Hostelworld account attached to it, so you can’t sign up to a second account using the same details.

If this is your first account, please double-check you have entered all the details correctly and try again.

If you are still receiving error messages, contact Customer Support detailing your problem and they will be happy to help.
