What’s an auto-number?
An Auto-number’s a standard Salesforce type comprised of unique alphanumeric characters, that set in every time a new Record gets inserted.
Using auto-numbers makes sense.
- Users, as well as automated processes, can infer Record Types without inspecting each Record from within.
- Apart from other details, these too can be referenced to pull up Records and aid faster discovery for a larger batch of Records.
- You can avoid name conflicts for individual Records with similar names, especially to avoid high stakes queueing errors.
- Users can preserve insert sequences without even trying, or even go as far as to use these as proxies for time-of-insert.
Code Illustration
For our part, we’ve implemented an Apex trigger that runs whenever new Records are inserted to check criteria and, in turn, calls a Handler Class(as is best practice) to make updates to assign the Record an Auto-number based on the Record Type inserted.
Take the case of a walk-in-interview drive inviting both developers and testing/quality professionals.
Also, these are auto-generated upon Record Creation within a Text Field that throws up an error on attempting manual entry as depicted below.
Finally, we get finished Record Details (, or more precisely, Job Details) that were auto-generated for each Record, or Job Type.
Now that you’ve seen Auto-numbers fairly closely, we give you our source code to dive into, like always.

Summary
In the above the sections above, we went over the fundamentals of assigning Auto-numbers based on Record types through an Apex Trigger.
We hope this demonstrates the use of Auto-numbers for your own Record search and discovery processes.
