More Wells Fargo & Co customers may have been affected by a scandal over phony accounts than previously believed, the third-largest U.S. lender said in a regulatory filing on Wednesday.
Wells Fargo had previously estimated that up to 2.1 million customers may have had checking and credit-card accounts opened in their names without their permission over a period of several years.
As part of an expanded review there could be “an increase in the identified number of potentially impacted customers,” Wells said.
The search for unauthorized accounts now covers a broader time frame, from 2009 to September 2016. An ongoing analysis of customer data may also be turning up more affected customers, according to Wells’ annual 10-K filing with the U.S. Securities and Exchange Commission.
