Most states already have some type of mask mandate, but some have no statewide rule — either leaving it as a recommendation or giving the authority to local officials.
Three states recently added face mask mandates: North Dakota, Iowa and Montana. Montana’s goes into effect November 20.
On November 13, North Dakota Gov. Doug Burgum announced a new measure requiring face coverings in indoor businesses and indoor public settings as well as outdoor public settings where physical distancing isn’t possible. The order is effective through December 13.
And on November 16, Iowa Gov. Kim Reynolds signed a proclamation that requires a face mask when people are in an indoor public space and unable to social distance for 15 minutes or longer.
Here are the states with no statewide mask requirement.
Gov. Doug Ducey, a Republican, allows individual counties to mandate a mask, but does not have a statewide initiative. Scottsdale was the first to make masks mandatory starting June 19. Other major municipalities with requirements include Phoenix, Tucson and Flagstaff.

Though there is no statewide mandate, Gov. Bill Lee, a Republican, signed an executive order granting the mayors in 89 counties the authority to issue mask requirements.
Masks are not a political statement, Biden says
In a speech Monday, Biden implored Americans to stop politicizing masks and social distancing.
“Please, I implore you, wear a mask,” the President-elect said. “Do it for yourself, do it for your neighbor. A mask is not a political statement but it is a way to start pulling the country together.”
“And if they refuse, I’ll go to the mayors and county executives and get local masking requirements in place nationwide,” he said.
“Wearing of face masks in public corresponds to the most effective means to prevent interhuman transmission, and this inexpensive practice, in conjunction with simultaneous social distancing, quarantine, and contact tracing, represents the most likely fighting opportunity to stop the Covid-19 pandemic, prior to the development of a vaccine,” researchers in Texas and California wrote back in June.
