Members of the public are being warned that penalty fines will apply from Friday as new laws on face coverings come into force across England.
Under latest guidelines, people will be required to wear face coverings in shops, supermarkets and high street outlets.
It comes in addition to fresh guidance on public transport and healthcare centres earlier this month - with face cover-ups now mandatory across the UK.
The current rules require anyone travelling by bus, coach, train, tram, Tube, ferry or plane to cover their face while on board.
The guidelines exclude school transport, though Uber and Addison Lee have both made face coverings compulsory for passengers and drivers.
The Government has been advising the public to wear face coverings on the high street since May 11.
However, now it's set to become the law.
A 'face covering' can be anything from a scarf to a shield, as long as it covers your mouth and nose - though children and some adults are exempt from the new guidelines.
The changes follow Scotland where face coverings have been mandatory in shops since last week.
The new rules will be enforced by the police, not shop workers who should instead "should encourage compliance", officials said.
The policy comes into play on July 24, although ministers made the announcement earlier in order to give "people time to prepare", according to the Environment Secretary George Eustice.
Health secretary Matthew Hancock said: "The death rate of sales and retail assistants is 75% higher amongst men and 60% higher amongst women than in the general population."

He added: "There is also evidence that face coverings increase confidence in people to shop."
Those who do not adhere to the rules face a fine of up to £100.
It will be reduced to £50 if paid within 14 days. In Scotland, a £60 on-the-spot fine applies instead.
