If you searched “Navistar VIN decoder,” you’re almost certainly holding the VIN of a truck badged International, not one badged “Navistar.” Navistar was never a name stamped on a hood or grille; it’s the corporate entity that has built International trucks since 1986, and as of October 2024 it operates under yet another name. This page explains that relationship in plain terms and covers the WMI codes, plant codes, and VIN structure you need to decode the truck itself. For model-specific detail on the LT, RH, MV, HV, and CV Series, see our International brand page; the mechanics below apply to any of them, since it’s the same manufacturer either way.

About Navistar

International Harvester was founded in 1902 through the merger of the McCormick and Deering harvesting-machine companies, and it built its first motor vehicle, the Auto-Buggy, in 1907. For most of the 20th century, IH was known equally for farm equipment (tractors, combines) and for trucks. That changed in the mid-1980s: IH sold its agricultural line to Tenneco in 1985 (the roots of today’s Case IH), and as part of that sale it was required to retire the International Harvester name. On January 7, 1986, the remaining truck-and-engine business was renamed Navistar International Corporation.

Navistar spent the next three and a half decades as an independent, publicly traded truck and engine maker, building International-brand trucks and buses and Navistar-brand diesel engines. In 2021, Germany’s TRATON SE, the commercial-vehicle holding company majority-owned by Volkswagen Group and parent of MAN and Scania, completed a $3.7 billion acquisition of the shares of Navistar it didn’t already own, folding Navistar into the TRATON GROUP alongside those brands. Then, on October 1, 2024, Navistar, Inc. changed its legal name to International Motors, LLC, closing the loop by returning the corporate name to the brand that had always appeared on the trucks. International Motors, LLC is headquartered in Lisle, Illinois, and still builds International-badged trucks and engines and IC Bus school and commercial buses.

Two related entities kept the Navistar name after the 2024 rebrand: Navistar Canada, Inc., which handles Canadian assembly and distribution, and Navistar Defense, LLC, which builds military and defense variants. If your VIN starts with a WMI assigned to either of those (see below), your truck is a Navistar-badged Canadian or defense-market unit rather than a US-market International.

Navistar / International WMI codes (positions 1-3)

The first three characters of your VIN, the World Manufacturer Identifier (WMI), identify the manufacturer, country, and vehicle type. Here are the WMIs on file with NHTSA’s vPIC database for International Motors, LLC (the US legal entity, formerly Navistar, Inc.) and its Navistar-named sister companies:

If your VIN starts with any code above, it’s a genuine product of the Navistar/International manufacturing family, regardless of which name is on the title. An “incomplete vehicle” WMI (1HT, 1HV, 1HA, 3HT, 3HV) means the truck left the factory as a cab and chassis for a second-stage manufacturer to finish, common on vocational trucks like dump bodies, tow trucks, and utility rigs.

How to read a Navistar/International VIN: position by position

Every VIN built since the early 1980s follows the ISO 3779 17-character standard. The 17 characters split into three blocks:

Here is what each position means specifically on a Navistar-built truck.

Position 4: Chassis configuration

Like other heavy-truck makers, International dedicates a character to axle arrangement and chassis type rather than body style, since fleet buyers spec a truck by drivetrain first. Position 4 distinguishes straight trucks from truck-tractors and encodes the axle configuration (4×2, 6×4, 6×6, and so on).

Positions 5-6: Model, cab, and GVWR class

These characters jointly identify the model line and GVWR class. This is where you’ll see the current International lineup: the LT Series (Class 8 long-haul tractor), RH Series (Class 8 regional-haul), MV Series (Class 6-7 medium duty), HV Series (Class 7-8 vocational), CV Series (Class 6-7 medium duty, produced through 2026), and the electric eMV. GVWR rides on the same characters, from Class 6 (19,501-26,000 lbs) through Class 8 (33,001 lbs+), so one model line can carry several codes depending on how it’s specced.

Positions 7-8: Engine, fuel, and brakes

These positions identify the engine family, fuel type, and brake system (air or hydraulic). International’s own engines include the A26 and S13 heavy-duty diesels; trucks in this lineup have also shipped with Cummins engines, including the X15 and L9, depending on model year and customer order.

Position 9: Check digit

The check digit is the most important single character in any VIN, calculated from the other 16 characters using a fixed weighting table and modulo-11 math. If even one character is mistyped, the check digit won’t match, and any compliant decoder or fleet-management system will flag the VIN as invalid.

Position 10: Model year

The 10th character maps to a model year on a repeating cycle used across the entire North American VIN standard. Skim the chart below to translate yours:

The letters I, O, and Q are never used in any VIN, including Navistar/International, because they look too similar to the digits 1 and 0.

Position 11: Assembly plant

The single character at position 11 identifies the specific factory that built the truck. International currently assembles trucks at its Escobedo plant in Mexico (Class 8), its San Antonio, Texas plant (Class 6-8 diesel and electric), and, through 2026, its Springfield, Ohio plant (CV, MV, and HV Series), which the company has agreed to sell as it winds down CV Series production. IC Bus school and commercial buses are built at a separate plant in Tulsa, Oklahoma. Decode the full VIN with the tool above to confirm the plant that built your specific truck.

Positions 12-17: Serial number

The final six characters are the production sequence number assigned to your truck as it rolled off the line, making every VIN globally unique.

Where to find the VIN on a Navistar/International truck

International trucks are heavy commercial vehicles, and federal VIN-placement rules treat them differently from cars. Under 49 CFR 565.15, the windshield-visibility requirement applies only to vehicles with a GVWR of 10,000 lbs or less. Every International Class 6-8 truck is built well above that threshold, so there’s no windshield VIN plate to look for. Instead, look here:

• The certification/compliance label on the driver’s side door frame or hinge pillar, visible when the door is open. It lists the VIN, GVWR, GAWR, and date of manufacture
• The VIN stamped into the top flange of the left frame rail, typically over or near the front axle
• The vehicle’s title, registration, and dealer service records

The 17-character VIN standard covered here applies to trucks built since the early 1980s. If your truck predates the 17-character standard, an era when the company was still International Harvester, use our classic car VIN decoder guide.

Check Navistar/International recalls and safety information

Recalls on International-badged trucks, like all US motor vehicle recalls, are tracked by NHTSA and published by the manufacturer under its current name, International Motors, LLC. The fastest way to check a specific truck:

1. Decode the VIN with the tool above to confirm the model, model year, and GVWR class
2. Look it up at International’s official recall lookup or NHTSA’s recall database
3. Contact your nearest authorized International dealer for the free recall repair

Recalls are repaired free of charge regardless of vehicle age, mileage, or ownership history.

Frequently asked questions

Is Navistar the same company as International Trucks?

Yes. Navistar International Corporation was the name International Harvester’s truck business took in 1986 after it sold off its farm equipment line. The corporate name changed again on October 1, 2024, to International Motors, LLC, but it’s the same manufacturer that has built International-badged trucks all along. “Navistar” is a corporate and engine-brand name; “International” is what’s on the truck.

How do I decode my Navistar or International VIN?

Type the 17-character VIN from your truck’s door-frame certification label, frame rail stamp, or title into the decoder at the top of this page. Results return in seconds and include model, model year, chassis configuration, GVWR class, engine, assembly plant, and open recalls. No registration is required.

Where is the VIN on my International truck?

Unlike a car, an International’s VIN isn’t required to be visible through the windshield; that rule only applies under 10,000 lbs GVWR. Check the certification label on the driver’s door frame or hinge pillar, and the VIN stamped into the left frame rail near the front axle.

Is the Navistar VIN decoder free?

Yes. VinDecoderPlus decodes every Navistar-built VIN free, with no sign-up or credit card. Full vehicle history reports, including title records, accident history, and odometer history, are available as an optional paid upgrade.

Can a Navistar/International VIN be faked?

The 17 characters can be retyped, but the check digit at position 9 makes silent tampering nearly impossible: one changed character breaks the math. The VIN is also independently stamped into the frame rail, so a cloned door label won’t match the frame. If you suspect a cloned VIN, our guide how to check if a car is stolen by VIN walks through the next steps.
