How to Set a Default Value for a Dropdown in Microsoft Access
Question details
The user needs to set a default value for a dropdown list (combo box) or a table field so that new records automatically display a specific predefined value.

- Product
- Microsoft Access
- Device & OS
- not provided
- Scenario
- Setting up or modifying a database table or form where a specific text value or hidden identifier should be pre-filled when entering new data.
- Observed behavior
- The user wants to automate data entry by ensuring a new record opens with the dropdown already populated with the correct default value.
Before modifying your database design, check the Row Source of your dropdown to determine whether it stores the visible text (like a name) or a hidden identifier (like an ID number). You must use the corresponding format for your default value.
Set the Default Value in Table Design View
Apply a default value directly at the table level so that any form or query based on this table automatically inherits the setting.
Setting the default value directly on the table field ensures data consistency across your entire database, as the rule applies regardless of how the data is entered.
Right-click the target table in the Navigation Pane and select 'Design View'.
Click on the field name (e.g., the vessel name or identifier) where you want the default value applied.
In the Field Properties pane at the bottom, select the 'General' tab. Find the 'Default Value' property box and type in your desired value. If it is text, wrap it in double quotes (e.g., "VesselName").
Click the Save icon in the quick access toolbar or press Ctrl+S to apply the changes to your table.

Set the Default Value for a Form Combo Box
Apply a default value specifically to a form's combo box when you only want the default to appear during form-based data entry.

Frequently Asked Questions
Why is my default value not displaying in the Access dropdown?
If your combo box is bound to a hidden ID column (such as a primary key) instead of the visible text column, you must set the default value to the corresponding ID number rather than the text string.
Can I use an expression to set the default value dynamically?
Yes, Access allows you to use functions and expressions. For example, entering =Date() in the Default Value property will automatically populate the field with the current date.
How do I remove an existing default value from a dropdown?
Open your table or form in Design view, locate the Default Value property in the Field Properties or Property Sheet, and simply delete the existing text or expression.
