Definition

A docket prefix commonly associated with certain Mexico-domiciled authority records.

Why it matters

The prefix helps users distinguish the type of authority involved.

Where it appears in public records

FMCSA authority records and public lookup tools.

How to read it in this directory

In CarrierDataHub, MX Number is treated as an orientation term for reading public motor carrier records alongside MC Number and Operating Authority. It helps users understand what a field or status may point to before they open a company profile, compare identifiers, or move to an official lookup system.

What not to assume

MX Number should not be read as a stand-alone approval signal. Public records can use short labels, legacy authority language, missing values, or dates that lag behind filings, so the term is only one piece of a wider identity and authority check.

Next verification step

When MX Number affects a business decision, compare it with the legal name, USDOT number, docket number, operating status, and source date shown in the relevant public record. If the question involves authority, insurance, safety, or current operating status, confirm the current record in official FMCSA systems.
