Bobcat Serial Number Lookup: Find Year by Serial Number

Quick Answer: Bobcat Serial Number Location

Bobcat serial numbers are 9 digits split into two parts: the first 4 digits identify the model/engine combination, and the last 5 are the production sequence. The model year is printed directly on the identification plate.

Where to find it: R-Series (2020+) → right side rear above tailgate. M-Series (2010+) → right side of main frame. K-Series (2007-2014) → rear frame upright. For exact parts fit, always use the serial number—not just the model year.

This guide shows where to find the product identification plate, how to read the 9-digit (4+5) serial, and how to use published serial ranges to estimate model year. We ship Bobcat parts nationwide from the U.S.—use the serial for filters, hydraulics, rubber tracks, cab glass, and other fitment-sensitive parts.

Bobcat machines print the model year on the product identification plate. The serial itself typically follows a 9-digit (4+5) structure: the first 4 digits identify the module (model/engine combination) and the last 5 digits are the production sequence. For parts accuracy, use your serial number—not just model year.

Where to Find Your Bobcat's Serial Number

When you need parts, service history, or insurance documentation, the serial on the product identification plate is the ID that catalogs and dealers use. Location depends on equipment family and generation—start with the chart and diagrams below before calling a dealer.

Plate location by loader generation (right side of machine)

R-Series

2020–present

Right rear, above upper-right tailgate corner

M-Series

2010–2020

Right main frame, below cooling compartment

K-Series

2007–2014

Rear frame upright (right or left)

Compact excavators: R-Series plate is on the front of the cab beside the boom; M-Series is near the door beside the boom. See the full chart below.

On the machine

Check the product identification plate on the frame or cab (see series chart). Wipe paint and dirt before photographing every character.

In the operator's manual

Many manuals include a data-plate / machine information page where the dealer or owner recorded the serial at delivery.

Through Bobcat support

If the plate is missing or unreadable, Bobcat Customer Service (1-800-743-4340) can often help from ownership records or other identifiers.

Understanding the Serial Number Plate

The typical Bobcat machine serial is nine characters split as 4 + 5. The first four digits are the module code (model and engine combination). The last five are the production sequence. Year is printed on the plate itself—it is not reliably encoded in those nine digits.

Why You Need the Serial Number

The serial is the fingerprint parts catalogs use. Mid-series changes (hydraulics, harnesses, pumps, cab glass, track size) are often gated by serial break—even within one model year.

Maintenance records

Service history, warranty claims, and recall lookups are keyed to the machine serial. Keep a photo of the plate with your maintenance file.

Parts ordering

Ordering by model name alone is a common source of wrong-fit returns. Send the full 9-digit serial plus model (for example T650 / A3NW…) when requesting filters, seals, glass, or rubber tracks.

Insurance and registration

Insurers and title paperwork typically require the serial from the product identification plate as the equipment identifier.

Why Serial Beats "Model Year" for Parts

Bobcat parts catalogs are serial-driven. Year-only lookups can miss mid-series changes. Use the serial for precise fit.

Conclusion

Locate the product identification plate, record all nine digits and the printed model year, then use that serial for parts and service. If the plate is damaged, contact Bobcat Customer Service at 1-800-743-4340, or send us a photo and your model for a parts fitment quote.

Frequently Asked Questions

Where is the serial number on a Bobcat skid steer?

On R-Series loaders (2020+), check the right side rear above the tailgate. M-Series (2010+) have it on the right side of the main frame below the cooling compartment. K-Series (2007-2014) have it on the rear frame upright. Older models vary—check inside or outside the rear upright.

How do I find what year my Bobcat is?

The model year is printed directly on the product identification plate alongside the serial number. If the plate is missing or damaged, contact Bobcat customer service at 1-800-743-4340 with your serial number and they can provide the year.

What do the numbers in a Bobcat serial number mean?

Bobcat serial numbers are 9 digits: the first 4 digits identify the model number and engine combination (helping identify exact parts compatibility), while the last 5 digits are the production sequence number showing when your machine was built in the production run.

Can I look up Bobcat parts by serial number?

Yes. Bobcat parts catalogs are serial-driven, so the full 9-digit serial (not just the model year) is what dealers and catalogs use for correct fitment. Use our interactive Bobcat serial lookup for plate tips and matching parts, or send your model and serial on a parts quote.
