Add leading zeroes to numeric fields in ArcGIS Pro

Summary

When adding a stand-alone table or dataset formatted with leading zeroes in the numeric field to ArcGIS Pro, the zeroes are omitted from the attribute table by default. The leading zeroes can be re-added to the field by configuring the number format in the attribute table settings. This article provides the workflow to insert the leading zeroes in numeric field values in ArcGIS Pro.

The image below shows the NumberTestLong field without any leading zeroes in ArcGIS Pro. In this example, the leading zeroes are added to the NumberTestLong field.

Procedure

1. In the Contents pane, right-click the feature class, and click Data Design > Fields to open the fields view of the feature class.

2. Click the cell in the Number Format column for the row of the target field to format.
3. In the highlighted cell, click Options to open the Number Format dialog box.

4. In the Number Format dialog box, click the Category drop-down menu and select Custom.
5. For the Format string parameter, edit the number format specifiers as required. In this example, 000 is used. Click OK.

6. Click Save on the ArcGIS Pro ribbon in the Changes group.
