Quick answer

On most modern Case IH tractors, the factory PIN plate is on the right-hand side of the chassis near the cab step, and the same PIN is also stamped into the chassis frame casting nearby. The engine carries its own separate serial. Always cross-check the riveted plate against the engraved frame stamp — a mismatch is the single strongest stolen-equipment signal at the inspection stage.

Modern (post-2000) Case IH PIN format

Modern Case IH equipment built since approximately 2000 carries a 17-character ISO 3779 PIN. WMIs include 1B3 (Racine, Wisconsin, USA — Magnum row-crop and Steiger articulated 4WD), ZCFC (Saint-Dizier, France — Maxxum, Puma, Optum), HFL (Goodfield, Illinois — balers and planters), and 9BD (Curitiba, Brazil — mid-range tractors and Axial-Flow combines for the Americas). Because Case IH and New Holland are both CNH Industrial brands and share several factories, some WMIs are common to both.

Legacy Case IH serial format

Pre-2000 Case IH (and older International Harvester / Case-built) tractors use shorter OEM-specific serials — typically 6 to 7 digits with a model-line prefix. Pre-1985 IH tractors (1086, 1486, 1586) use IH-specific conventions that pre-date both the modern Case IH brand and ISO 3779.

Where to find the PIN plate on a Case IH

  1. Factory PIN / data plate (the riveted plate). On Case IH tractors the factory PIN plate is riveted to the right-hand frame rail near the front axle on utility and mid-range tractors (Farmall, Maxxum, Puma). On row-crop and 4WD tractors (Magnum, Steiger, Quadtrac) the plate is on the right-hand chassis rail under the cab step.
  2. Chassis engraving (the same PIN, stamped). CNH stamps the PIN directly into the chassis frame casting on the right-hand front frame on most Case IH tractors. On Magnum and Steiger machines the engraving is on the main frame just ahead of the cab or near the articulation joint.
  3. Engine serial (separate identifier). The engine serial is separate and stamped on the engine block — typically on the right-hand side near the injection pump. Most modern Case IH engines come from FPT Industrial (Fiat Powertrain Technologies), which is also a CNH Industrial subsidiary.
  4. Operator's manual and dealer service file. The PIN appears on the title page of the manual delivered with the machine and in any authorised Case IH dealer service-history record. If the seller cannot produce the manual or a dealer service record, that is itself a flag worth pricing in.

Model-specific variations

Case IH plate-position conventions vary by model family. The following are the locations to expect on the most common current and recent product lines:

  • Farmall and Maxxum utility tractors — plate on the right-hand frame rail near the front axle, with the engraving on the same rail.
  • Puma and Optum mid-range — plate on the right-hand chassis rail beneath the cab step, accessible without removing panels.
  • Magnum row-crop — plate on the right-hand main frame between the front of the cab and the cab step; chassis stamp on the same main frame.
  • Steiger and Quadtrac articulated 4WD — plate on the right-hand chassis rail near the articulation joint; engraving on the front frame just ahead of the articulation hinge.
  • Axial-Flow combines — plate on the right side of the cab base near the operator step, separate from the header serial.

How to verify the PIN is genuine

A correct PIN is one that decodes structurally and appears in three consistent places on the machine. Walk the machine and check, in order:

  • Plate vs engraving match. The 17-character PIN on the riveted plate must match the engraved chassis stamp character-for-character. Mismatched, partially mismatched, or "the plate fell off" stories are walk-away signals.
  • Rivet condition. Factory plates have factory rivets — uniform heads, consistent corrosion, no fresh tool marks. Fresh non-original rivets, missing rivets, or screws where there should be rivets are signals.
  • Paint and surface match. The area immediately around a factory plate should weather and corrode at the same rate as the surrounding metal. Fresh paint, polished metal, or chemical residue around the plate are signals.
  • Font and spacing. Compare the plate's font, character spacing and plate-edge profile against other Case IH machines of the same era. Counterfeit plates are usually recognisable by font or spacing differences from the factory original.
  • Engine serial recorded. The engine serial is its own identifier; record it separately and check that it appears in the maintenance history. A new engine is normal on a high-hour machine, but it should be documented.
  • Cross-check against a registry. Even a perfectly-formed PIN can be stolen. A registry cross-check (Machinetrail covers 14 European registries plus a stolen-equipment dataset in one lookup) is the last line of defence.

What to do after finding the PIN

With the PIN written down (all three places — plate, engraving, engine serial), the pre-purchase value comes from cross-checking that PIN against three failure-mode databases before money changes hands:

  1. Stolen-equipment registries. A stolen Case IH will be reclaimed by police regardless of how clean the paperwork looks. Machinetrail queries 14 European registries plus TER-Europe-style and NER-style stolen-equipment data in a single lookup keyed to the PIN.
  2. Open safety recalls. EU Safety Gate, member-state agencies (Bundesnetzagentur, RDW, Traficom) and OEM recall feeds. Open recalls on hydraulic, brake, or PTO systems are a measurable safety risk and a re-sale-value problem.
  3. Auction comparables and market value. What did similar Case IH machines actually sell for in the last 12 months? Decoded PIN plus model plus year plus hours plus region returns the range of recent sale prices.

Frequently asked questions

Where is the PIN plate located on a Case IH tractor?
On Case IH tractors the factory PIN plate is riveted to the right-hand frame rail near the front axle on utility and mid-range tractors (Farmall, Maxxum, Puma). On row-crop and 4WD tractors (Magnum, Steiger, Quadtrac) the plate is on the right-hand chassis rail under the cab step. The same PIN is also stamped into the chassis itself: CNH stamps the PIN directly into the chassis frame casting on the right-hand front frame on most Case IH tractors. On Magnum and Steiger machines the engraving is on the main frame just ahead of the cab or near the articulation joint. The engine carries a separate serial — The engine serial is separate and stamped on the engine block — typically on the right-hand side near the injection pump. Most modern Case IH engines come from FPT Industrial (Fiat Powertrain Technologies), which is also a CNH Industrial subsidiary. Always cross-check the plate against the engraving — a mismatch or fresh paint around the rivets is a primary stolen-equipment signal.
What does a modern Case IH PIN look like and how is it structured?
Modern Case IH equipment built since approximately 2000 carries a 17-character ISO 3779 PIN. WMIs include 1B3 (Racine, Wisconsin, USA — Magnum row-crop and Steiger articulated 4WD), ZCFC (Saint-Dizier, France — Maxxum, Puma, Optum), HFL (Goodfield, Illinois — balers and planters), and 9BD (Curitiba, Brazil — mid-range tractors and Axial-Flow combines for the Americas). Because Case IH and New Holland are both CNH Industrial brands and share several factories, some WMIs are common to both.
My Case IH serial is shorter than 17 characters. Is it real?
Yes — pre-ISO Case IH equipment uses an OEM-specific serial format that pre-dates the 17-character ISO 3779 standard. Pre-2000 Case IH (and older International Harvester / Case-built) tractors use shorter OEM-specific serials — typically 6 to 7 digits with a model-line prefix. Pre-1985 IH tractors (1086, 1486, 1586) use IH-specific conventions that pre-date both the modern Case IH brand and ISO 3779. The position-by-position decoding rules that apply to a modern 17-character PIN do not apply to these older serials; year and configuration have to be looked up from the published model-year break tables for the specific family.
What if the Case IH chassis plate and the engraved frame number don't match?
A mismatch between the riveted plate and the chassis engraving is the single strongest stolen-equipment signal at the inspection stage. Common patterns: a freshly painted plate over a different underlying engraving; a plate with non-factory rivet heads; a plate where the font and spacing does not match other Case IH machines of the same era. Walk away from the deal — and report the serial to the relevant national registry (TER-Europe, NER in the US, the Plant And Agricultural National Intelligence Unit in the UK). Do not accept "the original plate fell off and the dealer made a replacement" without paperwork from a recognised Case IH dealer attesting to the replacement.
Is the engine serial on a Case IH the same as the chassis PIN?
No. The engine serial is separate and stamped on the engine block — typically on the right-hand side near the injection pump. Most modern Case IH engines come from FPT Industrial (Fiat Powertrain Technologies), which is also a CNH Industrial subsidiary. The engine serial identifies the engine alone — on a re-engined machine the engine serial will not match the factory chassis-PIN-implied engine, and that's normal but should appear in the maintenance history. Always record both serials separately when documenting the machine, and never assume that decoding the engine serial returns information about the chassis or vice versa.
What if the Case IH PIN plate has been removed or is illegible?
Try the chassis engraving first — CNH stamps the PIN directly into the chassis frame casting on the right-hand front frame on most Case IH tractors. On Magnum and Steiger machines the engraving is on the main frame just ahead of the cab or near the articulation joint. On a legitimate machine the engraving survives even when the plate is gone. If both the plate and the engraving are missing or obscured, that's a strong fraud signal: factory plates do not fall off in normal use, and engravings can only be defeated with deliberate grinding. The next-best identifiers are the engine serial on the engine block and any telematics-system identifiers; combined, those can in some cases be matched back to an original PIN through the OEM dealer network — but the burden of proof shifts onto the seller, not onto you.
Does Case IH have a telematics system that records true hours separately from the dashboard?
Case IH also operates AFS Connect as a factory-fit telematics system that records hours and faults independently of the dashboard hour-meter — ask the seller for a current telematics report and compare it against the recorded service history. Whichever telematics system is present, dashboard hour-meters can be rolled back; telematics-recorded hours are much harder to alter and so are the gold-standard rollback check on any used Case IH.
