Use this form to upgrade or renew:
If you already have a FREE ZONE or KEY ZONE account with HDCN, you may use this form to upgrade your free zone LOGIN to the KEY ZONE, or to renew your KEY ZONE subscription.

Expired KEY ZONE logins:
Expired KEY ZONE logins are not removed; they simply drop back to FREE ZONE privileges. When you renew using this form, your LOGIN regains KEY ZONE access privileges for 1 year.

Renewals made before the KEY ZONE expiration date:
Note: Renewal time periods are automatically added to the current expiration date, so there is no penalty for early renewal.

Free zone upgrades
If you initially registered as a FREE ZONE user and did not get a paid subscription, please use this form to UPGRADE your existing login. After the upgrade, your login will REMAIN THE SAME, only now it will open up key zone directories on HDCN.

New users without a login ID
If you do not yet have an account or login ID with HDCN, please do not use this form. Instead, please use the reg.htm (new user) form.

Forgotten login IDs and/or passwords:
If you want to renew but you have FORGOTTEN your login ID or password, please go to this password retrieval form to find your login ID password.

Select the type of subscription before proceeding to the order form. You will then be prompted for your login and password.
