Frequently Asked Questions (FAQ)

What is an OUI?

OUI (Organizationally Unique Identifier) is a 24-bit number that uniquely identifies a vendor, manufacturer, or organization. It forms the first half of a MAC address and is assigned by the IEEE Registration Authority.

Why can't I find my MAC address?

Some possible reasons:
  • The MAC address format might be incorrect
  • The device uses a locally administered address
  • The OUI might be recently assigned and not yet in our database
  • The device might use randomized MAC addresses for privacy

Is this tool accurate?

Yes, our tool uses the official IEEE OUI database, which is the authoritative source for MAC address vendor assignments. The database is regularly updated to ensure accuracy.

Can I use this for commercial purposes?

Yes, this tool is free for both personal and commercial use. No registration or licensing is required.

Does this tool store my MAC addresses?

No, all lookups are performed locally in your browser. We do not store, log, or transmit your MAC address data to our servers.
