If you are working with the Google+ API for tracking or other purposes, you may have noticed that you need to match against the numeric ID for the G+ user account.
This isn’t the easiest thing to find and took me and a vendor quite a while so let me share what I figured out.
There are effectively 2 ways:
1) Via the URL of the profile page
This one is pretty straightforward For some accounts, clicking on a profile will take you to a URL like this:
Here the numeric ID is 116376707133710026460.
2) Via the link URL in posts
Now, for some G+ accounts, the URL structure is different. For instance, if you click on my G+ profile, you end up here:
So, how do I get to my numeric ID? You go to one of the user’s posts (you need to have public posts for this to work) and right-click and select ‘Copy link address’ or ‘Copy URL’ or whatever the option is for your browser:
If you paste this URL into a doc, you’ll see it’s in this format:
So, the numeric ID for my account is: 112665405531807287877.
Voila! I hope this helps if ever you have a service which needs numeric Google Plus IDs.
