Custom Fields Allowed Per Object

To enable installation of AppExchange apps on all Salesforce editions, you can install additional fields beyond the edition limits if those fields come from an AppExchange certified managed package. You can install additional fields up to the maximum hard limit allowed per object.

• The objects in the following list have a maximum hard limit of 900 custom fields.
• All other objects have a maximum hard limit of 800 custom fields.

Let’s look at a few examples using the objects in the list. For Enterprise Edition, you can create 500 custom fields on an object and install an additional 400 fields from an AppExchange certified managed package. For Unlimited Edition, you can create 800 custom fields on an object and install an additional 100 fields from an AppExchange certified managed package.

These objects have a maximum hard limit of 900 custom fields.

If you have an AppExchange certified managed package installed in your org and that package expires, the custom fields in that package count against the edition custom field limit regardless of whether the Don't Count towards Apps, Tabs, and Objects Org Limits field is selected. For more information about AppExchange packages and limits, see the edition and org limits in Before You Install an AppExchange Package.

You can create up to 300 custom fields for activities, as long as your Salesforce org has fewer than 700 million tasks and events. If your org has more than 100 custom fields and now has more than 700 million tasks and events, you can’t create any more custom fields. However, your preexisting fields are retained to prevent data loss. To regain the ability to create up to 300 custom fields, use Salesforce Archive, Data Cloud, or third-party data archiving solutions to archive your activities, and then delete archived activities to reduce the number of activities in your org.

Custom Field Type Allocations

The maximum number of activities, long text area fields, rich text area fields, relationship fields, and roll-up summary fields varies according your Salesforce edition.

Note For custom compound fields, each component counts as one custom field toward your org’s limits. Each geolocation field counts as three custom fields: one for latitude, one for longitude, and one for internal use. Similarly, each custom address field counts as nine custom fields: one each for street, city, postal code, country code, state code, geocode accuracy level, longitude, and latitude, plus one for internal use.
