The Advertising Standards Authority of Singapore (ASAS) is an advisory council to the Consumers Association of Singapore (CASE). It was set up in 1976 to promote ethical advertising in Singapore and is the self-regulatory body of the advertising industry.

ASAS regulates the advertising industry through the Singapore Code of Advertising Practice (SCAP). The responsibility of ensuring truthful advertising lies with both advertisers and consumers. This works in the interest of both advertisers and consumers because it ensures that through fair play, there is a balance of trust and responsibility between them.

What we do

  • Provide advice and guidance when advertisers, advertising agencies and media owners are in doubt over the acceptability of advertisements – particularly before publication. However, the ASAS is not intended to be a clearing-house for the approval of all advertising.
  • Handle consumer complaints about questionable advertising practices in all media.
  • Advise on any business-to-business advertisement feedback, provided that it is brought to the attention of the ASAS in accordance with the procedure of lodging a complaint. ASAS is able to rule on disputes between members of the Singapore Advertisers Association, the Association of Advertising and Marketing Singapore, Advertising Media Owners’ Association of Singapore and the Association of Broadcasters.
  • Issue sanctions by
    • withholding advertising space or time from advertisers, and withdrawal of the trading privileges from advertising agencies. Both these sanctions are applied by the media owners.
    • exercising the option of publishing details of the outcome of the investigations, i.e. naming advertisers who have breached the code. The adverse publicity would have an impact, particularly on recalcitrant offenders.
    • referring the matter to CASE for action to be taken under the Consumer Protection (Fair Trading) Act for recalcitrant advertisers who repeatedly ignore the SCAP by persistent marketing of false, misleading or unsubstantiated claims.
