Increase Maximum Number of Custom Fields per Entity

This article answers the question: why can't I create more custom fields on an object, and what are my options once I hit the limit? The maximum number of custom fields per object is controlled by your Salesforce edition and can't be increased by Support directly.

Provisioned Limits by Edition

How to Check the Custom Field Limit on an Object

In Salesforce Classic

1. Go to Setup.
2. In the Quick Find box, enter the name of the object.
3. Select that object from the results.
4. Click Limits.
5. Check the limit on the Custom Fields row.

Hard Limits and AppExchange Managed Package Fields

Additional fields can be added beyond edition-specific limits, provided they come from a certified managed package on the AppExchange (Salesforce's marketplace for pre-built apps and add-ons). These additional fields can be installed up to the maximum hard limit per object.

For example, in Enterprise Edition you can create up to 500 custom fields per object and install an additional 400 fields from an AppExchange-certified managed package. In Unlimited Edition, you can create up to 800 custom fields per object and install an additional 100 fields from a certified managed package.
