These limits are flexible and can be increased upon request. If you need more domains, please [contact our support team](/help) for assistance. ### Wildcard domains - **All plans**: Support for wildcard domains (e.g., `*.acme.com`) - **Requirement**: Vercel must be able to answer the DNS challenge for the wildcard SSL certificate. Use [Vercel's nameservers](/docs/domains/working-with-nameservers), or [delegate certificate validation](/docs/domains/working-with-domains/add-a-domain#use-wildcard-domains-with-an-external-dns-provider) if you can't change nameservers ### Custom domains - **Hobby**: Up to 50 custom domains per project - **Pro and Enterprise**: Unlimited custom domains per project, subject to the soft limits above - **SSL certificates**: Automatically issued for all verified domains - **Verification**: Required for domains already in use on Vercel ## Multi-tenant preview URLs Multi-tenant preview URLs are available exclusively for **Enterprise** customers. This feature allows you to: - Generate unique preview URLs for each tenant during development - Test changes for specific tenants before deploying to production - Use dynamic subdomains like `tenant1---project-name-git-branch.yourdomain.dev` To enable this feature, Enterprise customers should contact their Vercel account representative. ## Custom SSL certificates Custom SSL certificates are available exclusively for **Enterprise** customers. This feature allows you to: - Upload your own SSL certificates for tenant domains - Maintain complete control over certificate management - Meet specific compliance or security requirements Learn more about [custom SSL certificates](/docs/domains/custom-ssl-certificate). ## Rate limits Domain management operations through the Vercel API are subject to standard [API rate limits](/docs/rest-api#rate-limits): - **Domain addition**: 100 requests per hour per team - **Domain verification**: 50 requests per hour per team - **Domain removal**: 100 requests per hour per team ## DNS propagation After configuring domains or nameservers, DNS typically takes 24-48 hours to propagate globally. Use tools like [WhatsMyDNS](https://www.whatsmydns.net/) to check propagation status. ## Subdomain length limits Each DNS label has a [63-character limit](/docs/deployments/generated-urls#truncation). For preview URLs with long branch names and tenant subdomains, keep branch names concise to avoid resolution issues. --- [View full sitemap](/docs/sitemap)
