Why Verify the Serial Number on Construction Equipment?

Buying used construction equipment can be a smart way to save money and access powerful machinery. But before you seal the deal, verifying the serial number (SN) is crucial to avoid potential headaches and ensure you're getting what you pay for.

A clean SN confirms the equipment's legitimacy and protects you from:

  • Fraud: Tampered or fake SNs can mask stolen equipment or hide major repairs.

  • Safety Hazards: Unregistered equipment might lack proper maintenance or safety certifications—jeopardizing your crew and project.

  • Legal Issues: Purchasing stolen equipment can lead to legal repercussions and financial losses—even if you were none the wiser.

So, How Do You Verify the Serial Number for Equipment?

Ready to start checking digits? Here are some useful methods of verifying construction equipment serial numbers.

1. Manufacturer Databases

Head to the Source
Most manufacturers maintain online databases where you can enter the serial numbers and access details like model year, specs, and sometimes even ownership history. Think John Deere's "Equipment Technologies" or Caterpillar's "Product Identification System." We've included a list of some of these sources below.

2. Third-Party Registries

National Equipment Register (NER)
The National Equipment Register (NER) US-based registry helps track and verify construction equipment across the country. A paid search reveals ownership status, theft reports, and maintenance records.

Check the serial number plate for any discrepancies between the listing and the actual equipment. Look for signs of tampering or alteration.

Ask for Proof of Ownership
Request registration documents or bills of sale to verify the seller's legitimacy.
