The Security Industry Authority (SIA) says thousands of Scottish doorstaff have already signed up for the new SIA licence in Scotland.
Following SIA licensing in England and Wales, the extension to Scotland creates a single regulatory body for the private security industry in Great Britain.
In November 2007 it will become compulsory for those operating in designated security industry roles in Scotland to hold an SIA licence.
SIA Acting Chief Executive Andy Drane said: "I am pleased to officially launch SIA licensing for Scotland. This is good news for security companies, security operatives and the public.
"SIA regulation in Scotland will ensure standards of training and professionalism in the private security industry are the same across the whole of Great Britain."
Jennifer Pattinson, SIA head of investigation for Scotland said: "SIA licensing for Scotland will help protect the public by preventing unsuitable or poorly trained people from working in the private security industry and by raising standards of service.
Since July we have been communicating with all sectors of the security industry in Scotland to help them understand regulation. Between now and November we'll ensure that every person who requires a licence in Scotland has the support and guidance they need to obtain one."
