Seller verification that’s fast, accurate, and affordable
There’s no comparison: Middesk has the most complete, most accurate, and most recent business identity data on the market. Power your marketplace trust and safety strategy with the highest-quality KYB data available.
Fast
Every second counts during onboarding. Immediately approve, step up, or reject sellers in-flow based on authoritative data verification with Middesk’s unmatched 500 ms response time. No other KYB API provides business insights this comprehensive, this fast.
Accurate
With direct connections to the Secretary of State offices, the IRS, and other US government agencies, Middesk has official data on 100% of US businesses. Most business records are updated as often as every 2 hours, so you get the latest data sooner.
Affordable
Middesk for Marketplaces is a lightweight solution for top-of-funnel verification at a fraction of the cost of a full KYB identity report. Start with a Signal Score and only introduce step up verifications if greater risk is detected, or reject the riskiest sellers outright.
The INFORM Consumers Act compliance made easy
Middesk makes it easy to meet your regulatory obligations under the INFORM Act by verifying the required information on your high-volume third party sellers, and monitors for changes to help ensure your seller information remains current and compliant.
Tax IDÂ number
Validate the TIN and match it to the business name. If it doesn't match, we’ll perform a series of lookups to identify alternate name possibilities.
Business address
Match the submitted address to the SOS, NPI, or FMCSA records. Verify the address is a physical address or flag if the address belongs to a registered agent, CMRA, private mailbox, or PO box.
Valid government record or tax document
Remove an onboarding step by automatically retrieving documentary evidence such as Articles of Incorporation and Certificate of Good Standing associated with a business.
First and last name
Verify the submitted person matches the officers in the SOS filing, or perform KYC and fraud checks on sole proprietorships with Socure — all through the Middesk API.
Email address and phone number
Verify the submitted email address and phone number matches the person and evaluate email and phone risks.
IDÂ verification
Confirm the authenticity of a government-issued ID, match the PII extracted from the ID against the input information, and match the ID headshot to a seller-submitted selfie.
