Case IH Serial Number Lookup & PIN Decoder
Last updated · 9 min read
Quick answer
A modern Case IH PIN is 17 characters (ISO 3779); older Case IHs use a 6–7 digit format. Many Case IH tractors share platforms with New Holland under CNH Industrial. Positions 1–3 identify the plant (WMI), 4–8 the product family and configuration, 9 a check digit, 10 the model-year letter, 11 the sub-plant, and 12–17 the serial sequence. Use the position table below to read your own PIN — or paste it into the Machinetrail lookup for a free decode plus recall, theft, and registry cross-check.
Case IH and New Holland share platforms — what that means for your PIN
Before you decode anything: Case IH is one of two flagship agricultural-equipment brands inside CNH Industrial. The other is New Holland. The two brands are not parallel competitors — they are sister brands that deliberately share factories, chassis, transmissions, hydraulic systems, and engines. The same Racine, Wisconsin assembly line that builds the Case IH Magnum 380 also builds the New Holland T8.435; the same Saint-Dizier, France line that builds the Case IH Puma 240 also builds the New Holland T7.270.
The visible differences are sheet metal (Case IH red vs New Holland blue), cab trim, console layout, electronic-control software branding (AFS Connect on Case IH; PLM on New Holland), and dealer channel. The underlying mechanical platform is largely identical. This matters when decoding a serial number for three reasons:
- The WMI does not always tell you the brand. Several CNH WMIs are shared between Case IH and New Holland because the same plant builds both. The product-family digits in positions 4–8 of the VDS are what actually pin down whether a unit shipped as a Case IH or a New Holland.
- Recall scope often spans both brands.When CNH issues a recall on a chassis, hydraulic, or engine component, the recall typically applies to both the Case IH and the New Holland badge of that platform. A "Case IH only" recall search will miss recalls listed under the New Holland twin.
- Parts and known-issue patterns are shared.Reliability data for a Case IH Magnum is informative about the New Holland T8 of the same year, and vice versa. Machinetrail's known-issues list joins both badges where the platform is shared.
Pre-1985 Case IH heritage is more complicated still: J.I. Case acquired International Harvester's agricultural division in 1985, and pre-acquisition IH tractors (1086, 1486, 1586, etc.) use IH-specific serial-numbering conventions that pre-date both the modern Case IH brand and the ISO 3779 standard.
Modern PIN vs older serial format
Two distinct serial-number eras to recognise:
- Modern (post-2000): 17-character ISO 3779 PIN on US-built and EU-export units. Decoded position-by-position using the table below. The full PIN is on the chassis plate and stamped into the frame.
- Pre-2000: 6 to 7 digit serial, often with a model-line prefix letter. The serial is unique within a model and within a model year, but does not encode plant or year by position. Decoding requires the published Case IH model-line serial-break tables.
- Pre-1985 (International Harvester era): IH-specific conventions that vary by model line; the 86-series, 88-series, and 50-series each have their own serial format. These are tractor-historian territory and Machinetrail will return a lower-confidence decode flagged before purchase.
What each position of a modern Case IH PIN means
Case IH PINs on equipment built since approximately 2000 follow the international VIN standard, ISO 3779. The 17 characters split into six functional fields:
| Pos. | Field | Meaning | Example |
|---|---|---|---|
| 1–3 | WMI (World Manufacturer Identifier) | Identifies CNH Industrial as the manufacturer and the assembly plant that built the machine. Case IH and New Holland share several WMIs because CNH operates the same factories under both brand names. | 1B3 / 3B3 = Racine, WI (Magnum + Steiger row-crop and 4WD); ZCFC = Saint-Dizier, France (Maxxum/Puma); HFL = Goodfield, IL (round balers, planters); 9BD = Curitiba, Brazil (mid-range tractors and combines for the Americas). |
| 4–8 | VDS (Vehicle/Product Descriptor Section) | Encodes the product family, model series, engine displacement, transmission, cab type, and drive layout. The exact mapping is CNH-internal and varies by product line; on cross-badged units the VDS is the primary field that distinguishes a Case IH build from its New Holland sibling. | On a Magnum-series tractor the VDS distinguishes Magnum 280 / 310 / 340 / 380; on a Steiger the VDS distinguishes 420 / 470 / 540 / 580 / 620 and tracked vs wheeled. |
| 9 | Check digit | ISO 3779 check digit calculated from the other 16 characters. A wrong check digit means the PIN was mistyped, mis-stamped, or fabricated — re-read the chassis engraving before going further. | Numeric 0–9 or letter X (representing value 10). |
| 10 | Model-year code | Single character indicating the model year. ISO calendar excludes I, O, Q, U and Z. The cycle repeats every 30 years, so K could mean 1989 or 2019 — read the WMI and serial range to disambiguate. | M=2021, N=2022, P=2023, R=2024, S=2025, T=2026, V=2027. |
| 11 | Plant / sub-plant code | Sub-plant or assembly-line code within the WMI's facility. On Racine-built Magnums this is typically a digit identifying the row-crop vs articulated 4WD line. | Single character A–Z or 0–9 depending on plant. |
| 12–17 | Serial sequence | Sequential build number for the model year and plant combination. 6 digits, zero-padded. Combined with positions 1–11 the full PIN is unique for a given machine. | 012345 = the 12,345th unit off that model-year line. |
ISO 3779 model-year letters skip I, O, Q, U and Z. The cycle repeats every 30 years; reading the WMI and the serial-sequence range together disambiguates the decade.
Case IH assembly plants and what they build
Knowing which plant built a unit is half of the pre-purchase intuition: build standards, common faults, dealer-network density, and parts-availability lead times all vary by factory.
| Plant | Role | Builds |
|---|---|---|
| Racine, Wisconsin (USA) | Magnum + Steiger main line | Magnum series row-crop tractors, Steiger articulated 4WD and Quadtrac. The historic CNH heavy-tractor home plant. |
| Fargo, North Dakota (USA) | Steiger 4WD assembly (legacy / overflow) | Historically a Steiger 4WD plant; some 4WD and tracked production has shifted between Fargo and Racine over the years. |
| Saint-Dizier, France | European mid-range tractor plant | Maxxum, Puma, and Optum series tractors for the European market and global export. |
| Goodfield, Illinois (USA) | Hay & forage / planter plant | Round balers (RB-series), large square balers, and Early Riser planters. Often badged identically with New Holland equivalents off the same line. |
| Curitiba, Brazil | Latin-America tractor and combine plant | Mid-range Farmall and Maxxum tractors plus Axial-Flow combines for South-American and other emerging markets. |
| Sorocaba, Brazil | Sugar-cane harvester plant | Austoft sugar-cane harvesters — Case IH's specialty product for tropical agriculture. |
Where to find the serial number on a Case IH tractor
- Right-hand frame rail. The factory chassis plate is riveted to the right-hand chassis rail, typically near the front axle or just below the cab door pillar on Magnum, Steiger, Maxxum, Puma, and Optum series tractors. The plate carries the full 17-character PIN plus model designation, gross vehicle weight, and the CNH logo.
- Engraved into the chassis frame. Case IH stamps the PIN directly into the frame casting on the right-hand side, so the engraved PIN survives even if the plate is removed or destroyed. Always cross-check the plate against the engraving — a mismatch is a primary stolen-equipment signal.
- Engine serial number (separate).Stamped on the engine block — on FPT engines, typically on the right-hand side of the block near the fuel injection pump, or on a small plate riveted to the rocker cover. This identifies the engine, not the chassis. On a re-engined tractor it will not match the factory chassis PIN — that's normal but worth flagging in the maintenance record.
- Cab pillar VIN sticker. Some 2018+ row-crop units carry a duplicate PIN sticker inside the cab on the door pillar — convenient for sellers because it can be photographed without crawling under the chassis.
- Operator's manual + dealer service file.The PIN appears on the title page of the operator's manual delivered with the tractor and in any authorized-Case-IH-dealer service-history record. A dealer-printed service report keyed to the PIN is the single highest-quality pre-purchase document.
AFS Connect telematics — what it tells you and what it doesn't
AFS Connect is Case IH's telematics and data-management platform. It has been standard or available as a factory option on row-crop and high-horsepower tractors since approximately 2018, and the underlying telemetry hardware is the same module CNH installs on equivalent New Holland units (where it's branded PLM Connect / PLM Intelligence).
What the registered owner can see through the MyCNHi Store / AFS Connect web portal and mobile app:
- Live machine data: location, engine on/off, current speed, current load.
- Lifetime hours and fuel use, graphed over time.
- Basic fault-code feed with severity and timestamp.
- Field-productivity reports — area worked, application rates, yield (when paired with appropriate sensors).
- Software-update notifications for the ECU and display.
What is dealer-channel only, not visible to the owner:
- Full ECU fault-history log with diagnostic-trouble-code detail.
- Service-bulletin compliance — which TSBs have and have not been applied.
- Software-version history at the module level.
- Warranty-claim history — what was repaired under warranty and when.
For a 2018+ Case IH, asking the seller for either (a) AFS Connect screenshots showing lifetime hours and recent faults, or (b) a recent dealer-printed service-history report keyed to the PIN, is the single highest-leverage pre-purchase step. A reluctant or evasive answer there is a meaningful signal on its own.
What to do once you've decoded the serial number
A correct decode is just the structural-validity check — it confirms the PIN is well-formed and resolves to a real configuration. The pre-purchase value comes from cross-referencing that PIN against three failure-mode databases:
- Stolen-equipment registries. NER (US), TER-Europe (UK/EU), and the 14 European registries Machinetrail queries in a single lookup. A stolen tractor will be reclaimed by police regardless of how clean the paperwork looks.
- Open safety recalls. EU Safety Gate, member-state agencies, and OEM recall feeds — joined across the Case IH and New Holland badges of any shared CNH platform. Open recalls on hydraulic, brake, or PTO systems are a measurable safety risk and a re-sale-value problem.
- Auction comparables and market value. What did similar machines actually sell for in the last 12 months? Decoded PIN + model + year + hours + region returns the range of recent sale prices — across Mascus, TractorHouse, AgriAffaires, and regional auctioneers.
All three are bundled into the €19.99 Machinetrail standard report; the free preview surfaces the recall count, top-5 known issues, and two recent auction prices. The €49.99 premium tier (coming soon) adds dealer-channel hour-history reconciliation when the seller provides AFS Connect access.
