Dear Costco Member,
The U.S. Centers for Disease Control recently announced new guidance regarding COVID-19 and vaccines. Among other things, the CDC now says that fully vaccinated people no longer need to wear a mask in most settings, except where required by state and local laws. People are considered fully vaccinated 2 weeks after their second dose in a 2-dose series, or 2 weeks after a single-dose vaccine.
Based on this new guidance regarding vaccine effectiveness, beginning May 14, 2021, we are modifying our policy regarding face coverings in some U.S. Costco locations.
U.S. locations with no state or local mask requirements - revised policy
In Costco locations where the state or local jurisdiction does not have a mask mandate, we will allow members and guests who are fully vaccinated to enter Costco without a face mask or face shield. We will not require proof of vaccination, but we ask for members’ responsible and respectful cooperation with this revised policy. Face coverings will still be required in healthcare settings, including Pharmacy, Optical, Hearing Aid. Costco continues to recommend that all members and guests, especially those who are at higher risk, wear a mask or shield.
U.S. locations with state or local mask requirements - no policy change
In those Costco locations where the state or local jurisdiction does have a mask mandate, we will follow the state or local regulations and continue to require members and guests to wear a face mask or face shield. Children under the age of 2 are exempt. If a member or guest has a medical condition that prevents them from wearing a mask, they must wear a face shield.
As before, our goal is to continue to provide a safe shopping environment for our members and guests and to provide a safe work environment for our employees, while following public health advice and applicable laws.
Thank you for your continued cooperation and support.
President and CEO
