The Process

1

Enter your input

Type a VIN, select a vehicle, search a product, or enter values for calculation.

2

We validate and check

GearVerify validates your input and checks against public data sources or runs calculations.

3

Review your results

Get clear warnings, next steps, and official source links to verify further.

4

Verify with official sources

Always confirm critical information with the official agency, manufacturer, or dealer.

Data Sources

We use official government databases including:

  • NHTSA - Vehicle identification and recall data
  • CPSC - Consumer product recall data
  • FCC, FDA, USDA - Additional verification sources (where applicable)

All data sources are credited and linked in our Data Sources page.

Calculators

Our calculators use standard formulas validated by industry standards:

  • Tire Size Calculator - Standard tire geometry formulas
  • Towing Capacity - Official towing and payload guidelines
  • Wheel Offset - Industry-standard fitment calculations

All formulas are documented and can be verified independently.

Limitations

GearVerify is a verification helper, not a guarantee. Important limitations:

  • Recall data can be delayed or incomplete
  • VIN decoding provides model-level data, not complete vehicle history
  • Calculators are estimates based on user-entered values
  • A "no match" result does not guarantee safety

Always verify with official sources before making critical decisions.

Privacy

GearVerify tools run in your browser. We don't store full VINs, personal information, or sell your data.
