ShowMojo randomly generates agent and shackle codes the first time you order CodeBoxes. All your CodeBoxes are then preconfigured with these agent, shackle and vendor codes. You will find the codes on the Digital Access page.
Please note: these code presets apply only to CodeBoxes purchased through ShowMojo. If you purchased the CodeBox elsewhere, you should have received these codes (or at least the agent code) when you purchased the CodeBox. To update the codes on a CodeBox to match the presets in your ShowMojo account, see the article to Change the Agent, Vendor or Shackle Codes on a CodeBox.
