Mississippi is a proud member of the International Registration Plan (IRP), a cooperative agreement between the U.S. states, the District of Columbia, and Canadian provinces. This system simplifies vehicle registration for commercial carriers that operate across multiple jurisdictions. Instead of having to register separately in every state you drive through, IRP allows you to obtain one "apportioned" plate and a cab card showing all jurisdictions you’re authorized to operate in. It’s not just a convenience, it’s a legal requirement for many types of commercial vehicles crossing state lines.
Who Needs an Apportioned Tag in Mississippi?
If you're operating a commercial vehicle across state or national borders, it's important to understand whether you're required to register under IRP. In Mississippi, apportioned registration is necessary for any vehicle that has a gross vehicle weight (GVW) over 26,000 pounds, has three or more axles regardless of weight, or is used in interstate commerce. This means that if your vehicle meets any of these conditions and operates in more than one state or province, you must have an apportioned tag.
Typical users of IRP registration include owner-operators, motor carriers, and trucking companies engaged in cross-state hauling. These are businesses or individuals involved in long-haul or regional transportation. It’s important to note, however, that trucks used exclusively for personal reasons or for operations limited within the state of Mississippi do not need to participate in IRP.
What Do You Need for Mississippi IRP Registration?
If your power unit has two axles and a gross vehicle weight over 26,000 pounds, has three or more axles regardless of weight, or if the combined weight of the power unit, trailer, and load exceeds 26,000 pounds, it qualifies for IRP registration.
To apply for apportioned registration in Mississippi, you’ll need the following documents:
- USDOT Number
- Mississippi Business Address (proof may be required)
- Proof of Title or Lease Agreement
- Vehicle Information: VIN, weight, year, make, model
- Proof of Insurance
- Actual or Estimated Distance Traveled in each state/province
- FEIN (Federal Employer Identification Number) or SSN (for sole proprietors)
- Completed Schedule A, B, and C forms (part of the IRP packet)
Additional Mississippi IRP Requirements and System Access
Mississippi allows carriers to register their vehicles under the International Registration Plan (IRP) through the Taxpayer Access Point (TAP) system. TAP is the state's online platform for submitting IRP applications and managing account updates, including the addition or removal of vehicles from an existing IRP account.
The state also participates in the Performance Registration Information Systems Management (PRISM) program, a federal initiative managed by the Federal Motor Carrier Safety Administration (FMCSA). PRISM links safety data with vehicle registration to promote compliance and improve safety monitoring across jurisdictions.
As part of this integration, all registrants must provide their USDOT number and Taxpayer Identification Number (TIN) when applying for IRP in Mississippi. If a vehicle is leased, the USDOT number and TIN of the motor carrier responsible for the vehicle's safety are required instead. This applies to every vehicle listed under the IRP account.
Additionally, the MCS-150 form (Motor Carrier Identification Report) must be updated within the past 12 months, for every USDOT number associated with the account. Carriers can update their MCS-150 online via the FMCSA's SAFER system.
Mississippi provides access to key documents and forms in PDF format, including the IRP Manual (last revised in July 2017) and the official IRP Application. These resources are essential for understanding compliance requirements, registration procedures, and account maintenance. A Notice of Intent to Register Vehicle for IRP form is also available, though it's important to note this particular form does not apply to buses or straight trucks.
IRP Registration Renewal
IRP registration in Mississippi is not a one-time process. Carriers are required to renew their registration every year. The renewal involves updating your actual mileage traveled per jurisdiction and ensuring your fleet and business information is still accurate. Timely renewal is essential, as missing the deadline can result in late penalties, rejected applications, or even suspension of your registration. It’s best to keep your records organized year-round to make the renewal process as quick and painless as possible.
