The industry group formed to secure and weed out fraud in the digital advertising supply chain says it has seen a jump in companies interested in joining the program over the past few months.

More than 350 companies have now applied for verification registrations by the Trustworthy Accountability Group (TAG), with an application increase of more than 75 percent in just the past three months.

Applicants represent 26 countries on six continents, the group said in a blog post Monday.

Applicants undergo a proprietary background check and review process driven by Dun & Bradstreet before they can be approved by TAG.

Once approved, companies can be verified by other companies in the ecosystem by name or by their unique, persistent TAG-IDs in the TAG Registry.

“In less than three years, TAG has established itself as the preeminent global organization fighting crime and increasing transparency in digital advertising, and we are aggressively building out TAG’s staff and infrastructure to support our growing program and member needs,” said Mike Zaneis, CEO of TAG.
