Salesforce, as a powerful customer relationship management (CRM) tool, utilizes unique identifiers for records in its database. These identifiers are represented by 15 and 18 character IDs, each serving specific purposes. Understanding the differences between these IDs is essential for efficient data management within the Salesforce platform.

This article aims to clarify the differences between 15-digit and 18-digit Salesforce IDs and provide insights into their usage.

Salesforce IDs: The Basics

Before we explore the differences between 15 and 18-digit Salesforce IDs, let’s first understand the basics of Salesforce IDs. Salesforce uses a unique 15-character ID to identify each record in the system. These IDs are case-sensitive and contain a combination of letters and numbers.

15-Character IDs

The 15-character Salesforce IDs are case-sensitive and are primarily used in user interfaces, reports, and data exports. These IDs are derived from a case-insensitive version of the original 18-character ID and are often displayed to users for reference and identification purposes.

18-Character IDs

The 18-character Salesforce IDs are case-safe and can be used in various scenarios, such as data manipulation through APIs, data imports, and integrations. These IDs are created using a case-sensitive encoding algorithm to ensure accuracy and reliability when dealing with data across different systems and platforms.

Key Differences and Use Cases

18-Character IDs


For a Salesforce record with the 18-character ID “0036F0000246BhVQAU” the corresponding 15-character ID would be “0036F0000246BhV”. This transformation involves removing three characters and adjusting for case sensitivity.

Best Practices


In conclusion, Salesforce IDs play a pivotal role in uniquely identifying records within the platform. While the 15-digit IDs are the standard and widely used, the 18-digit IDs offer additional capabilities for handling complex data scenarios and integration processes. Understanding the differences between the two formats and applying them judiciously based on specific use cases is essential for efficient data management and seamless Salesforce operations.

With this knowledge, you can leverage the appropriate Salesforce ID format based on your specific business needs and optimize your data management processes within the Salesforce ecosystem.
