User Information List in SharePoint 2016/2013/2010

Most of us know that SharePoint has many hidden lists to perform various tasks. Now we are doing deep dive on the “users” list. This list is one of the important lists exists at the site collection level. The hidden Users list was there from MOSS onwards and you can see this list even in SharePoint 2016 also.

Here we will discuss what is a user information list? How we can retrieve the user information list from the browser? How we can get user information list by using the server object model URL? How we can retrieve user information fields using the server object model?

Note: This list can be accessed by only Site Collection administrators and FARM administrators.

What is User Information List in SharePoint 2013?

The “User Information List” in SharePoint stores the information about a user with some metadata configured/added to the user as part of Active Directory (AD) like user Picture, DisplayName and Login Name (domain\user-id) e.t.c.

How User Information List gets data?

As soon as you add / grant access to a user at subsite/ Site Collection level SharePoint added a new entry in this list with the latest information of that user from AD. In precise if there is any change in user details especially in user-email (or) user role SharePoint add one more new entry in this list as there is a change in user’s metadata. So, sometimes we end up finding more than one entry for one user.

How to access User Information List in UI?

The User Information List can be accessed via the browser by navigating to “/_catalogs/users/simple.aspx” from your site.

Connect with User Information List using Server side Object Model

We can connect to this hidden list to get the user information for the required user. Please find the below code snippet for the same.

// Instantiates the User Information List
SPList userInformationList = SPContext.Current.Web.SiteUserInfoList;
// Get the current user
SPUser user = SPContext.Current.Web.EnsureUser(@"CONTOSO\krishna");
// The actual User Information is within this ListItem SPListItem userItem = userInformationList.Items.GetItemById(user.ID);
string pictureURL = userItem["Picture"].ToString();

With the above code snippet, you can get the picture URL of the user. Which clearly shows that reading information from this list is as same as any other list in SharePoint.

User Information List Fields

I would like to make our life easy, below is the code snippet to get all the fields and their internal names.

You can copy this code in a Console application to see the results.

SPWeb spWeb = new SPSite(;
SPUser user = spWeb.ensureUser(@"CONTOSO\krishna");
SPListItem item = spWeb.SiteUserInfoList.Items.GetItemById(user.ID);

Foreach(SPField objfld in item.Fields)
Console.WriteLine("Field Name:: {0}, Field Internal Name :: {1}",objfld.title,objfld.InternalName);

User Information List in SharePoint 2010

Now, we can see the user information list in SharePoint 2010.

User Information List is a hidden list maintained by SharePoint 2010 to stores and maintains a user information profile for authenticated users at the site collection level. A user also can update the profile information from the My Settings link. So for a particular user, there will be only one user profile information across all the sites in the site collection.

The information may be like email, displayname, loginname etc.

You can see the list from the below URL




You can also use the SharePoint 2010 object model to access user information list by using the SPList class like below:

SPList userInformationList = SPContext.Current.Web.SiteUserInfoList;

But if you are using SharePoint Server and you have configured User Profile Service application to import profiles, in that case, the information are copied from User Profile to User Information List by two timer jobs “User Profile to SharePoint Full Synchronization” and “User Profile to SharePoint Quick Synchronization”. Here your profile information can be updated from the Active Directory or from My site feature.
