Salesforce ID Converter

Convert between 15-char and 18-char Salesforce ID formats

Valid ID• 15-char ID (case-sensitive)

Input

Salesforce ID

How does the conversion work?

The 18-character ID adds a 3-character suffix that encodes the case of each character:

Split the 15-char ID into three 5-character chunks
For each chunk, create a 5-bit number where each bit is 1 if the corresponding character is uppercase
Map each 5-bit number to a character using: ABCDEFGHIJKLMNOPQRSTUVWXYZ012345

This allows case-insensitive tools to preserve the original case information.

Frequently Asked Questions

Why do Salesforce IDs have two formats?

The 15-character ID is case-sensitive and used internally by Salesforce. The 18-character ID adds a 3-character suffix that encodes the case, making it case-insensitive for use in tools like Excel.

When should I use 18-character IDs?

Use 18-character IDs when working with external tools (Excel, databases) that might change case. Use 15-character IDs in Apex, SOQL, and Salesforce APIs.
