Communicating with Mexico (DQ/DR, KQ/KR & RQ/RR)
This section describes Nlets user access to Mexican Commercial Driver License (DQ/DR), Driver History (KQ/KR) and Commercial License Plate records (RQ/RR).
Overview
Effective November 21, 1991 the United States recognized the commercial driver license issued by the Secretaria de Comunicaciones y Transportes (SCT), the Licencia Federal de Conductor, as being comparable to a U.S. issued commercial driver license (CDL).
U.S. enforcement officers can encounter Mexican drivers with a licencia federal legally operating a commercial motor vehicle (CMV) in the U.S., as Mexican for-hire carriers can legally operate from Mexico through the U.S. to a destination in Canada.
Though rare, such movements are legal because the carrier is not engaged in commerce in the U.S., and thus does not need U.S. operating authority issued by the U.S.DOT, Federal Motor Carrier Safety Administration (FMCSA). Such operations DO need to comply with all safety and other requirements, e.g., driver licensing, fuel taxes, registration taxes, vehicle safety.
- In addition, Mexican based (domiciled) private carriers, principally owned by a U.S. investor, may obtain operating authority from the FMCSA to operate anywhere in the United States.
There are a number of companies which claim this is their ownership status and have obtained this type of operating authority. Although they may legally operate anywhere in the U.S., these carriers are restricted to hauling private carriage (their own products). It is also possible for a Mexican domiciled company to get similar authority for hauling exempt commodities (basically agricultural.) All such Mexican companies can use Mexican drivers with a licencia federal issued by the SCT to operate their commercial vehicles in the U.S.
Mexican Commercial Driver License
The eLicencia system responds to Nlets user driver license queries (DQ & KQ), regardless of the type of ORI assigned to them, e.g. FBI or Nlets.
Users can inquire to the eLicencia to obtain license and status information about federally issued Mexican commercial driver licenses, just as such driver license queries (DQ & KQ) can be made to U.S. state driver license files for any U.S. issued license.
- A license status inquiry to the eLicencia is made by addressing a driver license query (DQ or KQ) message to the destination address of "MX".
- All inquiries and responses are in a fixed format.
- At this time, the eLicencia application only supports requests using the operator license number (OLN).
- Name and date of birth inquiries are not currently supported, but are anticipated in the future.
- Mexico will not return images on either a DQ or KQ.


Help Files
On-line HELP Files
Users may access the standard help file Nlets has always supported for providing explanatory or supplementary information provided by the application. For the eLicencia application it covers highlights of Mexican federal commercial driver licenses, and the eLicencia.
The HELP file is accessed by sending an Administrative Message (AM) to: MXOLNHELP
Driver's License Query Requirements
To send a Driver License Query (DQ) or Driver History Query (KQ) to the Mexican eLicencia application the following entries are required:
- Standard Nlets header, message type, sending ORI
- Destination code MX
- License number from the license document (must always include the alphabetic characters which are the beginning of the license number)
- Category(s).
No spaces or non-alphanumeric characters are allowed.
The control field and control characters are optional.
The Driver's License Query (DQ) requirements for a Mexican licencia federal inquiry are similar to a Driver's License Query (DQ) or Driver's History Query (KQ) inquiry for a U.S. state issued driver license.
The table below provides a description of the Mexican driver's license number field requirement.

Mexican OLN/ plus up to 4 category(s)
8-15 plus 4 i.e., 8-19
Alphanumeric
Combination of DL# and "CATEGORY" of Mexican driver license in DL#/CAT order. DL# must begin with alpha letters shown as beginning of number on the document. If more than one "category" shown on license, they may all be included in OLN field after the DL#. This combination currently is the required equivalent of U.S. OLN for Mexican LIFIS.
Free form fields such as "RSTR/", "STATUS/", "OLT/", etc., are used to provide information on any restrictions, status of the license, the U.S. equivalent CDL class and explanations regarding verifications in process.
All information will be provided in English.
If there are any questions on this or any other parts of the response, consult the Nlets HELP file by sending an Administrative Message (AM) to MXOLNHELP.
In the near future there are plans to begin supporting a KQ (driver history) capability. Initially this will be for convictions that result from citations issued by U.S. enforcement while the driver was operating in the U.S. This capability to respond to a KQ inquiry was expected to begin initial operations sometime in 2000.
Test Driver's License Number (OLN) and Category Values
WARNING: These test OLN values must be entered EXACTLY, or an error message likely will be received in response, instead of the expected illustrative results.

Mexico Commercial License Plate File
The Mexico Commercial License Plate File is housed in Mexico City and is provided to Nlets through the Federal Motor Carriers Safety Administration's connection in New York. All commercial vehicles in Mexico that cross Mexican state boundaries and into the United States are required to be federally registered and included in this file. If the vehicle is commercial and you receive a "not on file", it is not registered and is in violation of US-DOT operating authority. Queries can be run by license plate only.
More information may be obtained by emailing FMCSASupport@TechAnax.com. This file has been available for many years so it is very possible that your message switch may already be prepared to send RQs to destination MX.

The following records can be used for testing:
- LIC/533HY7.LIY/2015.LIT/PC
- LIC/455ER3.LIY/2015.LIT/PC
General notes:
- MX responds to an RQ only on Federal License Plate Registration (Interstate CMV). Mexican State issued license plates are not in the database, thus, any query to a Mexican State Credential will result in a negative response.
- If a MX RQ results in a "NOT ON FILE", the vehicle is not registered in Mexico and is in violation of US-DOT Operating Authority.
Possible license plate status codes:
- ASSIGNED (ONLY POSITIVE STATUS)
- AVAILABLE
- CANCELLED
- STOLEN OR LOST
- WITHDRAWAL PER RULE
- DAMAGED
- WITHDRAWAL NOTICE
- WITHDRAWAL IMPOUNDED
- NOT RECEIVED
- WITHDRAWAL EXCHANGED
- WITHOUT DECAL
- INCOMPLETE DATA ENTR
- PREVENTIVE SEIZURE
- MISSING
- WITHDRAWAL NEW NAME
- UNDER INSPECTION
Possible registrant status codes:
- REGISTERED
- WITHDRAWN
- SUSPENDED
