What that error means, the two cases behind it, and how to get your teammate in.
You are inviting a teammate and the form stops with a message like "There is already a user with this email or phone number in your organization." It means that email address, or that phone number, is already attached to someone in your company on Cargado. There are two reasons, and they need different things from you.
The invite went out, and it is still sitting in their inbox unaccepted. Do not send a new one. Go to Organization, then Members, find their row, open the menu on the right and choose Resend invite.
Your teammate can also do this without you. Ask them to open the resend-invite page on cargado.com, enter the same email address, and a fresh invite arrives.
If they accepted an invite at some point, they do not need another one. They need to sign in. If they cannot, that is a sign-in problem rather than an invite problem, so send them to the password reset on the sign-in screen, or to two-factor help if the password is fine and the second step is the blocker.
The same message appears when the phone number is already in use, even if the email is new. This catches people who work across two Cargado accounts, for instance a broker account and a carrier division. Invite them without the phone number, and they can add it later.
Sometimes the address really is new to your company and the error still fires, because of an older record we need to clear. We cannot fix that from the invite form, and neither can you. Send success@cargado.com the email address you are trying to invite and your company name, and we will clear it.
