The company's CEO, Craig Jelinek, said those who are unable to wear a face mask due to a medical condition will need to wear a face shield.
Jelinek said the new policy is to help provide a safer environment for Costco's members and employees.
The retailer was one of the first companies to issue a blanket requirement for face coverings at the start of the pandemic.
