To learn how to create a\nbucket, see the [Create buckets guide](/storage/docs/creating-buckets). For general information on\nbucket naming, see the [bucket naming guidelines](/storage/docs/buckets#naming).\n\nRequirements for domain-named buckets\n-------------------------------------\n\nCloud Storage considers bucket names that contain dots to be domain\nnames. As such, a bucket containing a dot in its name must:\n\n- Be a syntactically valid DNS name (for example, `bucket..example.com` is not valid because it contains two dots in a row).\n- End with a currently-recognized top-level domain, such as `.com`.\n- Be created by a user who is [authorized to work with the domain name](#who-can-create).\n\nExamples of valid domain-named buckets include `example.com`,\n`buckets.example.com`, and `www.example.co.uk`.\n\nWho can create a domain-named bucket\n------------------------------------\n\nTo create a bucket that uses a domain name, you must establish that you are\nauthorized to use the domain name. People authorized to use a domain name\ninclude:\n\n- Verified owners of the domain or parent domain\n- Delegated owners of the domain or parent domain\n- [Verified site owners](https://support.google.com/webmasters/answer/7687615#manage-owners) of the domain or parent domain\n\nSite owners cannot create the bucket when a domain owner exists. This allows the\ndomain owners to tightly control who can create domain-named buckets.\n\nFor example, say you have an IT staff member who owns the website that uses\n`http://reports.example.com`. Once they go through verification of that site,\nthey can create buckets such as `reports.example.com` and\n`annual.reports.example.com`. However, if you later verify that you own the\ndomain `example.com`, only you can then create these buckets. Since you\nverified the domain `example.com`, you can also create the bucket `example.com`.\nAs the site owner, your IT staff member can no longer create buckets.\n\nDomain ownership verification\n-----------------------------\n\nIf your project intends to have a domain-named bucket, the team member creating\nthe bucket must demonstrate that they are authorized to create a bucket in\nthe given domain. When you intend to [host your domain's content](/storage/docs/hosting-static-website) in a\nCloud Storage bucket, the recommended verification method is to\nverify domain ownership.\n\nCloud Storage uses the [Search Console](https://search.google.com/search-console) to verify domain ownership.\n\n**To verify domain ownership:**\n\n1. Open Search Console. You must be signed in with the user account that\n you will use to manage ownership of your domain.\n\n [Open Search Console](https://search.google.com/search-console)\n | **Note:** If you have previously verified a property in Search Console, click the drop-down associated with the previous property's name, and click **Add property**.\n2. In the **Domain** pane, enter the domain or sub-domain that you want to\n verify, and click **Continue**.\n\n | **Note:** Generally, the domain you verify should be the root-level that you own, without any prefixes such as `www`. An example of a root-level domain is `example.com`.\n3. Follow the instructions that appear in the pane **Verify domain ownership\n via DNS record**.\n\n### Delegated owners\n\nOnce you have verified domain ownership, you can add additional\n*delegated owners* , who can also create buckets under the verified domain name.\nThese owners can include [service accounts](/iam/docs/understanding-service-accounts).\n\n**To add delegated owners to your domain:**\n\n1. Go to [Search Console's user management page](https://search.google.com/search-console/users). Make sure that the domain you want to manage is selected in the [property selector](https://support.google.com/webmasters/answer/10352053).\n2. Click **Add user**.\n3. In the dialog box, enter the email of the new owner.\n4. For **Permission** select \"Owner\".\n5. Click **Add**.\n\n| **Note:** You can only add domain owners if you are also a domain owner.\n\nTroubleshooting\n---------------\n\nSee the [Search Console help page](https://support.google.com/webmasters/answer/35179) for information on topics including:\n\n- Methods of verifying site ownership.\n- Verifying using a DNS TXT or CNAME record.\n- Troubleshooting common verification errors.\n\nWhat's next\n-----------\n\n- [Create a bucket](/storage/docs/creating-buckets).\n- Learn how to [host a static website](/storage/docs/hosting-static-website).\n- Learn about [bucket naming guidelines](/storage/docs/buckets#naming)."]]
