greenID has been part of Australian identity compliance since 2005 and is one of the approved Gateway Service Providers on the Australian Document Verification Service, now sold by GBG plc after its 2018 acquisition of VIX Verify. That rail is Australia-only, it answers matched or not matched with no confidence score, and everything around it is quoted on an order form. Didit covers Australia and 219 more countries on one /v3/ API, publishes the price of every module, and adds Business Verification, Transaction Monitoring and Wallet Screening that greenID does not sell.
greenID's strength is the Australian Document Verification Service, which only checks Australian government records and returns a plain matched or not matched. The first country you open outside Australia and New Zealand needs a second vendor.
GBG's published greenID product terms run on negotiated order forms with an annual minimum commitment, an invoice for any shortfall, and an early-exit charge equal to the remaining minimum-commitment fees for the term.
The greenID API reference lives on a customer-only wiki with no open sandbox, so the first integration question goes through sales instead of a terminal.
greenID and GBG are trademarks of GBG plc and its subsidiaries. References on this page are nominative, for comparison only, and do not imply affiliation or endorsement. The comparison reflects publicly available information as of September 2026, including GBG's published greenID product terms, GBG product pages, and the Australian Government's register of Document Verification Service gateway service providers. GBG's pricing is negotiated per customer and is not published, so no per-check rate is claimed for greenID here.
