Modify Standard Auto-Number Fields in Salesforce Classic
The unique identifiers for solution, case, and contract records are standard
auto-number fields. Each record is assigned a unique number with a specified format upon
creation. You can modify the format and numbering for these auto-number fields in Salesforce

To modify standard auto-number fields:
Customize Application
From Setup, enter the name of the object whose field you want to modify in the Quick Find
box, then select Fields.
Click Edit next to the name of the auto-number field.
For example, for cases, edit the Case Number field.
Enter a Display Format to control such formatting details as the minimum number of
leading zeros as well as any prefix or suffix for the number.
Format changes don’t affect existing records; they’re applied
only to new records.
Enter the number to be assigned to the next record that is created after you save your
changes.
Click Save.
Warning Salesforce warns you if the next number you enter isn’t higher than
existing numbers. However, it‘s possible to create duplicate numbers if you change the
auto-number format multiple times using similar formats each time.
