Can a Diffusion be converted into a Red Notice without my knowledge?

Yes, and this happens regularly. The requesting state’s NCB can submit a formal Red Notice request to Interpol’s General Secretariat at any time, often using the same underlying case file. You would not receive notification of this conversion. The only way to detect it is through periodic status checks. If a Diffusion exists, we typically recommend monitoring every 60–90 days, as conversion to a Red Notice significantly increases enforcement risk and visibility across all 196 member states.
