What Does the 'CRM' Code in Your Dynamics 365 URL Actually Mean?

Have you ever noticed something like crm4.dynamics.com or crm11.dynamics.com in your Microsoft Dynamics 365 URL? Wondering what these cryptic codes actually mean?

Let’s break it down.

In Microsoft Dynamics 365, the letters and numbers you see in the URL — such as crm4, crm11, etc. aren’t random. These are geographic data center codes that indicate where your CRM instance is hosted.

  • Example:
    If your URL is https://orgname.crm4.dynamics.com, the crm4 code tells us that your data is hosted in Europe.

These codes serve two important purposes:

  • Data Residency: Ensuring your data is stored in compliance with regional laws.
  • Performance Optimization: Hosting closer to your users reduces latency and improves speed.
