These special contact attributes can also make certain integrations and features even more powerful. In this article, we'll cover what these special contact attributes are and how to use them. ### Special Attributes for Contact Filtering Contact attributes contribute to Field Tools' powerful contact filtering capabilities on the Contacts \> All Contacts page.

For NGP VAN/EveryAction import (via sync instructions - see [here](https://help.actblue.com/hc/en-us/setting-up-integrations-impactive-help-center)), geographic attributes are imported automatically; no further action is needed. To import geographic contact attributes via CSV upload, **you must include the following column headers in your** CSV; use this *exact* column header to import data properly: ![Screenshot 2026-04-27 at 12.00.35 PM](https://help.actblue.com/hs-fs/hubfs/Screenshot%202026-04-27%20at%2012.00.35%20PM.png?width=564&height=631&name=Screenshot%202026-04-27%20at%2012.00.35%20PM.png) You can also upload additional special contact attributes via CSV; this data is not currently available for use in contact filters, but it is present in any export databases for analysis purposes. - Precinct (required column header: precinct\_name) - Address (address) - Ethnicity (ethnicity) - Gender (gender) - Date of Birth (date\_of\_birth): format YYYY-MM-DD - VAN ID (van\_id) - PDI ID (pdi\_id) - DWID (dwid) ### Custom Contact Data If you are looking to upload additional custom contact attributes outside of the lists above, you can always use Field Tools' [custom fields](https://help.actblue.com/hc/en-us/custom-fields-creating-and-managing-impactive-help-center) to power [dynamic variables](https://help.actblue.com/hc/en-us/using-dynamic-variables-in-texting-scripts-impactive-help-center). You'll first create a custom field (Data \> Custom Fields), then use the "slug" of that custom field as the column header in a contact CSV upload. This will import your custom contact attributes, which can then be used in contact filtering, dynamic variables in scripts, etc. [![](https://help.actblue.com/hs-fs/hubfs/Knowledge%20Base%20Import/21919175541143.png?width=563&height=410&name=21919175541143.png)](https://impactive-8d45e16b27c1.intercom-attachments-7.com/i/o/1031624591/3b6c76ca5641be34cc06ef4c/21919175541143?expires=1776792600&signature=66ca9da7d553a05fd7c809c5725b2f1ee2c137651484b54081c6534d1d4f8208&req=dSAkF898mYRWWPMW1HO4zURh1J0Gu%2BUgBZBSf1hP2vnI8UDtyuiK2GKrR99k%0AKvGnKvNXYFlAIpSX2OQ%3D%0A) -
