This SAE Recommended Practice establishes procedure for the issuance and assignment of a World Manufacturer Identifier (WMI) on a uniform basis to vehicle manufacturers who may desire to incorporate it in their Vehicle Identification Numbers (VIN). This recommended practice is intended to be used in conjunction with the recommendations for VIN systems described in SAE J853, J187, J272, and other SAE reports for VIN systems.
These procedures were developed to assist in identifying the vehicle as to its point of origin. It was felt that review and coordination of the WMI by a single organization would avoid duplication of manufacturer identifiers and assist in the identification of vehicles by agencies such as those concerned with motor vehicle titling and registration, law enforcement, and theft recovery.
Rationale
J1044 has been reaffirmed to comply with the SAE five-year review policy.
The VIN - WMI Technical Committee reports to the Vehicle Engineering Systems Group of the Motor Vehicle Council. The Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to the Vehicle Identification Number (VIN) and World Manufacturers Identifier (WMI) for road vehicles. The committee also makes recommendations for changes to US regulations and ISO Standards concerning VIN-WMI issues. The committee has successfully petitioned the National Highway Traffic Safety Administration (NHTSA) to promulgate rulemaking to revise the United States VIN regulation.
The committee's Phase I focus is to assess the content of the present VIN-WMI and consider the worldwide future needs (either expansion/reduction of code or change of code segment meanings) for on-road vehicles, specifically passenger cars, light- and heavy-duty trucks, multipurpose passenger vehicles, buses, motorcycles, motor-driven cycles, trailers, low-speed vehicles, and incomplete vehicles. The committee's Phase 2 focus is to assess the form and placement of the VIN-WMI on the on-road vehicles mentioned in Phase 1.
Participants in the SAE VIN - WMI Technical Committee include OEMs, suppliers, consulting firms, government, law enforcement, insurance, and other interested parties.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
