Find Base List Template ID

This PnP PowerShell script returns the base template name and template ID of any SharePoint Online list or library. Useful when building provisioning scripts that require a specific template type, or when auditing lists to understand how they were created.

Purpose

The script retrieves two key properties from a target list:

• TemplateTypeDisplayName — the human-readable template name (e.g. Document Library, Generic List, Calendar)
• BaseTemplate — the numeric template ID used in provisioning and schema definitions (e.g. 101 for Document Library, 100 for Generic List)

Prerequisites

• PnP.PowerShell module installed
• Read access to the target SharePoint site

$ClientId = ""
$SiteUrl = "https://tenantName.sharepoint.com/sites/siteName"
Connect-PnPOnline -Url $SiteUrl -Interactive -ClientId $ClientId

$list = Get-PnPList -Identity "listName"

Write-Output "List Template Name: $($list.TemplateTypeDisplayName)"

Write-Output "List Template ID: $($list.BaseTemplate)"
