Dynamics 365 Attribute Name lengths

Dynamics 365, Metadata 1 Minute

This article captures the maximum attribute name lengths allowed in Dynamics 365 (CRM). This is a simple thing but I carry on forgetting it and it is useful to have them always in mind.

  • Attribute Display Name max length = 50 characters
  • Attribute Unique Name max length = 41 characters
  • Attribute Description max length = 200 characters
  • Attribute Form Label max length = 100 characters

See below the corresponding screenshots locating those elements:

Software Engineer specialised on Microsoft Technologies with experience in large projects for different industrial sectors as developer, consultant and architect. I enjoy designing and developing software applications, it is my job and one of my hobbies. I’m interested in design patterns, new technologies and best practices. Making those part of the ALM process is a great challenge. Since 2008, I have been working with Microsoft Dynamics 365 (CRM back then), the Power Platform and Azure. I customise and extend the platform to provide tailored solutions and integrations based on service-oriented architectures and messages queuing. Motivated by community events and contributor in blogs, technical books, open source projects and forums, I was awarded Microsoft Business Applications Most Valuable Professional (MVP) for 7 years.
