The company said more than 3.5 million Swifties, as her followers are known, registered in advance as "verified fans" in the hope of getting tickets for her 52-city US tour in the pre-sale.
Despite issues during the pre-sale that Ticketmaster estimated affected about 15% of interactions across the site, the company said it still sold more than 2 million tickets - the most ever for an artist in a single day.
