Final answer:
The first step is to report the loss or theft to the badge issuer. The second step is to provide necessary documentation and proof of identity.
Step-by-step explanation:
The first step in getting a new badge if it is lost or stolen is to report the loss or theft to the appropriate authority. This can usually be done by contacting the badge issuer, such as your employer or the institution you're associated with. They will guide you through the process of obtaining a replacement badge.
The second step is to provide any necessary documentation or proof of identity. This may include filling out a form, providing a valid identification card, or providing any other information requested by the badge issuer to verify your identity.
