KYB Lookup
How KYB Lookup checks a KYB lookup
Quick answer. A KYB lookup is a stack of official sources. The legal entity comes from the state. The TIN match comes from the IRS. Sanctions come from OFAC. No single public page contains all three.
One fact, one source
People search “KYB lookup” hoping for one box. The useful version is a checklist with a URL for each line. Legal name and file number: secretary of state. Employer identification number: the company, confirmed through IRS TIN matching when you are eligible. Sanctions: OFAC Sanctions List Search.
Commercial data brokers republish pieces of this and add phone numbers and revenue estimates. Estimates are not records. If a field has no official source, label it as an estimate or leave it blank.
