Custom Domain | Zoho Forms - User Guide

Custom Domain

Custom Domains are used to promote your organization's brand in the form URLs to all your form respondents. If you do not want any reference to Zoho Forms in your form URL, you can use your own custom domain.

Customized Forms - Zoho Forms

Customize Form - Zoho Forms


By default, your form URL will be in the format as shown in this example:

Let's say your website is and you wish to embed your form in it with the domain, you can use such custom domain instead of the default Zoho Forms domain to showcase your organization's brand in the form URLs shared to all your respondents.


Using a custom domain can help:

  • Promote your brand

  • Increase the number of responses you receive via your forms

  • Makes it easier for your respondents to find and remember your organization


Before adding a Custom Domain for your forms, follow the below steps:

CNAME Record Mapping for Your Domain   

  1. You must own a domain or a sub-domain for your organization. Ensure that you can edit the DNS (Domain Name System) records for your custom domain in the settings of the domain provider.

  2. Add a CNAME (Canonical Name) record in your DNS records section in your domain provider. A CNAME record allows you to use your domain as an alias for another domain.

  3. Use the CNAME record to map your sub domain to the Hostname
    For example: CNAME

    Zoho Forms Public URL

    Map your domain or sub-domain to the Hostname

    It could take upto 48 hours for the changes to your domain to appear on the internet.

You can search for DNS propagation checker tools online to perform a DNS propagation lookup for your sub-domain name (Eg: ) and confirm if the DNS records are fully propagated.

Note CNAME records need time to propagate. If you have already updated your DNS, wait for 24-48 hours. If you try to add the custom domain in Zoho Forms before this time period, you may see an error.
