Decoding History: The Ultimate Guide to the International Harvester Tractor Serial Number Table

For collectors, restorers, and farmers who still trust the iron of yesteryear, few names carry as much weight as International Harvester (IH). From the legendary Farmall letter series to the powerful 06 and 56 series, IH tractors are cornerstones of agricultural history. However, buying or restoring one of these machines presents a common puzzle: What year was my tractor built, and what factory produced it?

• IH industrial tractors (3400, 2500, etc.) – Serialized separately.
• French or German-built IH tractors – Entirely separate sequences.

The Rule of Ranges: Your tractor was built in a specific year if its serial number is equal to or greater than that year’s starting number, but less than the starting number of the following year. International Harvester Tractor Serial Number Table-
