The US Company Lookup Tool is NOT TO BE USED to determine if a business or its Industry Codes are Valid. Only Companies that have acquired a DUNS Number, a complete record, and opted into the Marketable File appear in the Database. This means there are plenty of Valid Organizations that will not appear in our system.

Furthermore, any Company may assign any NAICS/SIC code(s) to themselves at any time, and change them at any time, without fulfilling any prerequisite or registering the change with a particular system. This means that the Primary source to confirm the Validity of an Industry code is typically with the Company itself. The only time NAICS/SIC codes aren’t completely self-assigned is when the Organization has to meet rules set forth by a government entity in order to do business in a Given Industry code in the given locale.

If trying to establish a Business relationship with someone, please direct them to this page if they are hesitating to progress due to Information found or lacking in the Company Lookup Tool.

Again, This is tool is not intended to be a Determining factor in establishing Business relationships.

Not all Organizations will appear in The Company Lookup Tool. Records are derived from the Marketable Database at Dun&Bradstreet (D&B), so only Organizations with a DUNS Number may appear in the Company Lookup Tool. Typically D&B Company Records aren’t included in our system if they are lacking information, opted to be delisted from the marketable file, or are being held off the Marketable list for an undisclosed reason by D&B.
If you have a DUNS Number, try finding your record on Once you Verify and Authenticate your identity, you should be able to access and update your information as needed there. If you have any issues, contact the Phone number in the link. If lacking a Record with D&B, you can sign up at their site.
