[Contacts](https://help.actblue.com/hc/en-us/actblue-field-tools-formerly-impactive-by-actblue#contacts) # How can we update contact data?  It's easy to update contact data in ActBlue Field Tools by simply re-importing contacts with their relevant data added or corrected. Field Tools uses phone number as the unique ID for contacts, so if you upload a contact with the same phone number as they already had within Field Tools, a duplicate contact will not be created - the same contact will simply be updated with whatever new or corrected data is imported. (Note that this is true for both contacts [imported](https://help.actblue.com/hc/en-us/importing-contacts-impactive-help-center) manually via CSV, or imported via integration with VAN/EveryAction, etc.) To give a very simple example - let's say that you originally imported a contact John Smith with a simple CSV like this: ![Screenshot 2026-04-27 at 11.35.34 AM](https://help.actblue.com/hs-fs/hubfs/Screenshot%202026-04-27%20at%2011.35.34%20AM.png?width=670&height=114&name=Screenshot%202026-04-27%20at%2011.35.34%20AM.png) A few days later, you realize that John's name is actually spelled 'Jon', so you need to update the contact. Easy! You just need to re-import the CSV with the information corrected, **using the same phone number for this contact** - Field Tools will match on that phone number as the contact's unique ID, and will thus update the data for that phone number accordingly: ![Screenshot 2026-04-27 at 11.36.22 AM](https://help.actblue.com/hs-fs/hubfs/Screenshot%202026-04-27%20at%2011.36.22%20AM.png?width=670&height=100&name=Screenshot%202026-04-27%20at%2011.36.22%20AM.png) After importing that second CSV - in the same way you normally [import a CSV contact list](https://help.actblue.com/hc/en-us/importing-contacts-impactive-help-center), via Contacts \> Lists \> + Import List - Jon's contact record will be updated with the new spelling of his name. Note that this method of updating contacts by re-importing them using the same phone number is also the way that an administrator can manually add tags and custom fields to contacts (without filling a report via the volunteer interface) -
