NEW YORK — Uber is offering riders a four-digit pin code to help ensure they’re getting into the right car.

The ride-hailing company rolled out the new feature Tuesday across the U.S. and Canada and said riders there will be able to use pin codes by the end of the week.

The development follows the death of 21-year-old Samantha “Sami” Josephson, who was murdered in March after getting into the car of a man impersonating an Uber driver. Her body was later found in the woods 65 miles away.

In New Jersey, where Josephson grew up, the state passed a law requiring ride-hailing drivers to display identification signs on the car’s front windshield and rear window. North Carolina passed a law requiring Uber and Lyft drivers to display lighted signs.

Uber has long provided riders with license plate numbers and the make and model of cars, and the pin code offers an additional layer of security, said Rebecca Payne, senior product manager at Uber. The best way to ensure you’re getting into the right car is to check the license plate, she said.
