Twitter plans to roll out a new verification service this week, owner Elon Musk tweeted.
The social media company intends to manually authenticate verified accounts, providing gold check marks to companies, gray checks to government entities and blue marks to individuals.
"Painful, but necessary," Mr. Musk said in the Nov. 25 tweet. More details would be coming soon, he added.
After Mr. Musk's $44 billion takeover of the company, Twitter started charging $7.99 a month for blue check marks but stopped giving them out after a rash of impersonator accounts, including one posing as Eli Lilly offering free insulin. Several pharma companies later stopped advertising on the site.
