What is Bulk Invite?
The Bulk Invite feature allows organizations to onboard personnel by uploading a CSV roster. Once uploaded:
Each listed user receives a welcome text message automatically (which can be scheduled in advance)
The roster can include optional user attributes such as rank, DOD ID and department. The department field automatically assigns users to the matching team in AOK.
Important: Department/team names must match the spelling in AOK exactly. If the name is spelled differently, AOK will create a new team instead of assigning the user to the existing one.
This process helps organizations scale onboarding quickly and consistently.
Before You Upload
Important Notes
Save your roster file as a .CSV file before uploading.
The Department column represents the user’s assigned team.
The first row of the CSV must match the template exactly (column headers), even if optional fields are left blank.
Phone Number Validation
Phone numbers are automatically validated during upload. Invalid or improperly formatted numbers will be flagged and must be corrected before invites are sent.
Announce the Program Internally
Before using Bulk Invite, notify personnel about the upcoming welcome text and the purpose of the program. Users who receive unexpected messages may mark them as spam, which can block future communication.
Prepare Team Leads
Make sure Team Leads are ready to build and manage their teams once invites are sent.
Team Leads are automatically assigned based on who creates the team.
Team Leads can organize users into teams and subteams after onboarding.
You can reassign or add additional Team Leads from the Team Directory by selecting the three dots next to a user’s name.

Things to Keep in Mind
Only Org Leaders and Org Admins can access and use the Bulk Manage tool.
Team Leaders can only add or remove users within their assigned teams and cannot perform organization-wide bulk uploads.
CSV files must be formatted correctly before upload.
Always coordinate internal communications before sending invitations.
