This move comes after several warnings following the mushrooming of internet cafes operating without licenses countrywide.
ZICTA Acting Public Relations Manager Edward Mulenga said it was illegal for any Internet café to operate without a trading certificate from ZICTA.
Mr Mulenga disclosed this to ZANIS in a telephone interview in Lusaka, on October 28.
The PRM added that the agency has started closing down internet cafes that are operating without trading licences, because the practice is unlawful.
He said all those who want to venture into the running of internet cafes should first register their company with Zambia Information and Communication Authority (ZICTA).
And Mr Mulenga further appealed to internet café owners to formally come on board and register their businesses with ZICTA, to avoid the risk of being closed down.
