CardDAV | Zoho Contacts


You can sync your Mac, iOS, Windows, and Android contacts from your computer or mobile device with Zoho Contacts using CardDAV. CardDAV is an open internet protocol for syncing contacts. It works based on 3 important aspects, the service URL, username, and password. These 3 must be valid to make the CardDAV protocol work. You also need to enter your data center specific URLs.

The following URL must be used according to device and region you're trying to connect.

If your Zoho account has 2FA, then you need to generate application-specific password by going to, then to Password under Security. We recommend setting up an application-specific password even if you don't have 2FA, this way your Zoho account will be safe even if your CardDAV synchronization is compromised.

If you have signed up in a different country than your region, then you can simply go to your page and replace 'accounts' with 'contacts' then add the suffix '/carddav' or '/.well-known/carddav' based on the type of client/device you are using (refer above table).

Here is a step-by-step guide for syncing your contacts with Zoho Contacts:
  • The Username will be your Zoho email address.
  • If you have enabled TFA for your Zoho Account, you must enter the app-specific password in the Password section.
  • Only your personal contacts will be synced from Zoho contacts.
