DoorDash will require its drivers to verify their identities more often as part of a larger effort to crack down on unauthorized account sharing.
DoorDash has been under pressure to ensure its drivers are operating legally. Over the summer, for example, it pledged to do a better job identifying and removing dangerous drivers after a flood of complaints of dangerous driving from cities.
Officials in Boston, New York and other cities have said that in many cases, people with multiple traffic violations continue to make deliveries using accounts registered to others.
The San Francisco delivery company said Thursday it was requiring some drivers to complete real-time identity checks immediately after they complete a delivery. Previously, drivers were occasionally asked to re-verify their identities before or after a shift.
DoorDash has introduced the new system in Los Angeles, Denver, Seattle and other cities, and said it planned a wider rollout next year.
DoorDash said it also has developed an advanced machine learning system that can flag potential unauthorized account access, including login anomalies and suspicious activity. If the company detects a problem, it will require drivers to re-verify their identity before they can make more deliveries.
U.S. drivers must verify their identities with a driver's license or other government-issued identification, and upload a selfie that matches their identification photo before they can do work for DoorDash. They also must submit to background checks, which require a Social Security number.
The company said it found that some drivers were getting around the requirements by sharing accounts with authorized users. In some cases, drivers who were not authorized to drive for DoorDash paid authorized users for access to their accounts.
