You can text message your Instacart delivery driver while or after the driver shops for your items. To contact your driver, log into the Instacart website, then go to “My orders”. Then, find the current order and click on “View order details”.
On the left-hand side of the screen, you should see your driver’s avatar and name. Click on the green speech bubble button next to the name to open a chat box. You can send your driver messages if you need help.
