International Registration Plan (IRP)—IRP is the acronym for the International Registration Plan. The IRP is a special plan for registering vehicles that must travel in two or more member jurisdictions.

International Fuel Tax Agreement (IFTA)—All interstate and inter-jurisdictional carriers that travel in IFTA member jurisdictions with a qualified motor vehicle must file fuel taxes through the International Fuel Tax Agreement (IFTA). IFTA member jurisdictions include all contiguous states (except Alaska and the District of Columbia) and Canadian provinces (except Northwest Territories, Nunavut, and the Yukon Territory)

Trip Permits—An IRP Trip Permit is required when a vehicle needs to travel through Georgia and the vehicle meets the criteria for apportioned registration under International Registration Plan (IRP), but does not have an apportioned registration for Georgia.
