Persona física and persona moral: how your RFC sets your documents

Cargado reads your RFC to tell whether you are a persona física or a persona moral, then asks for the documents that match.

Carrier
Updated
October 2, 2026

In 2 steps

  1. Enter your company's RFC in the carrier application
  2. Upload the documents for your taxpayer type

Cargado reads your RFC to tell which kind of taxpayer you are. A 13-character RFC belongs to a persona física, and a 12-character RFC belongs to a persona moral. The application then asks for the documents that match that type.

Step 1: Enter your company's RFC in the carrier application

In the carrier application, choose Mexico under Where is your company based? and type your company's RFC in the RFC field: the RFC tied to the SICT permit. The application checks that it is a valid RFC (three initial letters for a persona moral or four for a persona física, six date digits, a three-character suffix) before you can continue.

Top: the whole carrier application page, dimmed, with the RFC field highlighted and marked Step 1. Bottom, zoomed in: Step 2 of 3, Business identity, Identify your business, with Mexico selected under Where is your company based?, Legal business name Tres Comas Transportes, the RFC field with a 12-character RFC, the USDOT number question and Continue. Badge 1 marks the RFC field.
  1. RFC: the application reads it. 13 characters means a persona física; 12 characters means a persona moral.

Important: The Mexico application requires a valid RFC. A CURP is not accepted in its place.

Step 2: Upload the documents for your taxpayer type

On the documents step, a persona moral uploads five documents: the Constancia de Situación Fiscal (CSF), the acta constitutiva, the SICT permit, proof of address and the legal representative's ID. A persona física uploads four: the same list without the acta constitutiva. Every one of them is required to submit the application. The proof of address must be no older than three months. The ID is both sides of the INE in a single upload, or a single page of the passport.

Good to know

  • Questions about your registration: email carriers@cargado.com.
  • The step count: the figure shows Step 2 of 3 for a Mexico company with no USDOT number. Your application can show a different total, for example when you give a USDOT number and a verification step is added.
