In a posting on its Web site, the company warned fans they might have one of the canceled tickets if they did not buy directly from Ticketmaster or a venue box office.

The company said it would send notices to e-mail addresses connected to the voided tickets.

Cities hosting shows with canceled tickets include Philadelphia, New York, Washington, Sunrise, Fla., Auburn Hills, Mich., Chicago, Atlanta, Las Vegas and Atlantic City, N.J.

“It is a serious violation of the law to try to buy concert tickets using stolen credit card information and, when successful, to resell those tickets to unknowing consumer victims through resale Web sites,” Sean Moriarty, Ticketmaster’s president and chief operating officer, said in a statement.
