Since May 24, 2026, CIOT has become mandatory for all paid road cargo transportation operations, and for full truckload shipments, the system blocks registrations with freight rates below ANTT’s minimum rate.
The universalization of the Transport Operations Identifier Code (CIOT) has transformed the operations of companies, cooperatives, and independent truckers in the freight sector. As of May 24, 2026, CIOT now applies to all paid cargo operations, as new validations have reinforced electronic registration with minimum rate controls.
Prior to this 2026 update, the CIOT requirement mainly applied to contracts with independent transporters and equivalent operators. With ANTT Resolution No. 6,078/2026, the National Land Transport Agency expanded the scope of the code to include companies, cooperatives, and independent operators, making registration a standard part of the paid road freight contracting process.
CIOT serves as an electronic identifier for the operation. The registration includes information on the contractor, transporter, vehicles, origin and destination, type of operation, and freight value. This database allows for tracking compliance with contracts and enhances data traceability.

For full truckloads, rates below the minimum impede code generation
The primary practical change is observed in full truckload operations under the National Minimum Floors Policy for Road Cargo Transport. Starting with the new validations, the system now prevents registration if the reported rate falls below the applicable minimum.
The minimum rate is not a single value. It varies according to factors such as cargo type, vehicle configuration, number of axles loaded, and specific operation characteristics. ANTT provides tables and periodic updates for reference values.
As a result, CIOT is no longer just a number linked to freight; it now also serves as a compliance verification point. If a full truckload is subject to a minimum rate and the declared value does not meet the requirement, the code will not be generated until the data is corrected.
Companies need to align contracts, registrations, and travel documentation
The universalization increases the need for consistency among the contractor’s, transporter’s, RNTRC (National Register of Road Transporters), vehicles, and freight value data. Registration errors or discrepancies can halt the operation before the journey begins.
The new model is also connected to the MDF-e, the Electronic Manifest of Fiscal Documents. This integration enhances the cross-referencing of information and requires carriers, shippers, and system providers to review their issuance flows.
For truck drivers and hired companies, registration formalizes essential information and creates a verifiable trail regarding who contracted the service, who transported the cargo, and what value was declared. ANTT presents CIOT as a tool for traceability, oversight, and security for all parties involved.
Control now occurs before some operations enter the system
The most visible effect of the change is the preemptive control of some operations. Instead of relying solely on post-transport inspections, certain inconsistencies are blocked upon entry of the operation into the system.
This rule has been in effect since May 2026. Therefore, companies and transport professionals need to treat CIOT as a central step in paid freight operations, verifying the mode, registration data, and value before submission.
