title: Can multiple Google Analytics account have same profile ID?
body: <p>Is is possible that multiple Google Analytics accounts (e.g abc@gmail.com and xyz@gmail.com) have same <a href="https://developers.google.com/analytics/devguides/config/mgmt/v3/mgmtReference/management/profiles" rel="nofollow noreferrer">profile(view) Id</a> or is it unique across all the Google Analytics accounts?</p>
  
  <p>I am sure that web property is unique (as it is used to collect data from web/app) across multiple GA accounts but I am not sure about the profile IDs.</p>
  
  <p><strong>Here is the use case:</strong></p>
  
  <p>I am developing the web application which allows any user on internet to authorise his/her GA account and extracts the data from GA. The web application uses GA Reporting API V4 and performs caching mechanism based on Google Analytics username (i.e. abc@gmail.com).</p>
  
  <p>Now let's profile ID 123 from abc@gmail.com is shared with xyz@gmail.com and both the users wants to extract the same data for same profile 123 from GA. Now since the caching is done on GA Username, web application will consider it as two different requests but if caching is done on profile id, only one of the two requests will be considered as new request and the other will be served from cached result. That is why I need to know whether GA profile ID is unique across multiple Google Accounts or not considering profile ID is not shared with any other account. </p>

  <p>I have asked the same question to Google Advertiser community. Here is the link for reference.</p>
