Licensing minister Gerry Sutcliffe wrote to local authorities this week outlining plans to limit the increase in the number of lap-dance clubs and asking for their support.
The Fawcett Society and Object have pledged to contact local authorities across England and Wales to ask that they back the government plans.
Applications for lap-dance clubs are currently treated in the same category as karaoke bars and coffee shops. The government wants to recategorise them as "sex encounter establishments" for licensing purposes
Kat Banyard, campaigns officer at the Fawcett Society, said: "We will be getting in touch with all local authorities to ensure that they know the current situation and make their voices heard.
"We urge the Government to untie the hands of local authorities by licensing lap-dance clubs as sex encounter establishments, as sex shops and sex cinemas are."
The number of lap-dance clubs in the UK has soared to more than 300 since the first one opened in 1995, said Banyard.
