Create a site collection
This article describes how global admins and SharePoint admins in Office 365 can create classic SharePoint Online site collections from the Microsoft 365 admin center.
For info about creating sites that use the new templates (team sites and communication sites) in the new SharePoint admin center preview, see Manage sites in the new SharePoint admin center. For info about creating site collections in SharePoint Server, see Create a site collection in SharePoint Server.
Create a classic site collection
SharePoint Online has several classic templates. For example, you can create sites for blogs, wikis, record storage, and publishing.
Sign in to https://admin.microsoft.com as a global or SharePoint admin. (If you see a message that you don't have permission to access the page, you don't have Office 365 administrator permissions in your organization.)
In the left pane, select Resources, and then select Sites.
Select Add a site.
If you don't see the options above, select Admin centers > SharePoint and then select New > Private Site Collection. >
Fill out the new site collection properties:
In the Title box, enter a name for the site collection.
In the Web Site Address drop-down lists , select a domain name and a URL path—either /sites/ or /teams/ —and then type a URL name for the site collection.
In the Template Selection section, in the Select a language drop-down list, select a language for the site collection. You can enable the SharePoint multiple language interface on your sites, but the primary language for the site collection will remain the one you select here.
It's important to select the appropriate language for the site collection, because once it's set, it cannot be changed. After creating a site collection, verify the locale and regional settings are accurate. (For example, a site created for Chinese will have its locale set to China.)
In the Template Selection section, under Select a template, choose the template that most closely describes the purpose of your site collection. For example, if your site collection will be used for a team collaboration, choose Team Site.
For more information on templates, see Using templates to create different kinds of SharePoint sites.
In the Time Zone box, select the time zone that's appropriate for the location of the site collection.
In the Administrator box, type the user name of your site collection administrator. You can also use the Check Names or Browse button to find a user to make site collection administrator.
In the Storage Quota box, type the number of megabytes (MB) you want to allocate to this site collection. Do not exceed the available amount that is displayed next to the box.
In the Server Resource Quota box, accept the resource quota default. This setting no longer affects the resource amounts available for the site collection.
The new site collection will appear in the URL list. The URL is the site collection location at which the administrator can start to create and manage sites.
