The advert in question, which appeared in the national press from 12 February to 22 April this year, aimed to create public awareness of the scheme.
It stated: "Do you give to charities? Look for the tick. Charities with the Fundraising Standards Board tick have committed to be honest, respectful and accountable in their fundraising. Next time you support a charity, look for the tick so you can give with confidence".
One complainant claimed the ad implied that charities that were not members were generally untrustworthy. Another argued that the advert suggested that charities that were FRSB members were generally trustworthy in areas other than fundraising.
The ASA adjudication stated: "We considered that the ad made clear that the FRSB scheme related to fundraising only and merely encouraged people to look out for the FRSB tick before donating."
A spokeswoman for The Fundraising Standards Board said: "We are pleased that the ASA has not upheld the complaint regarding our national advertising. The national advertising campaign, and in particular the ‘tick' logo, was clear and unambiguous. We took advice from the Code of Advertising Practice Copy Advice Team prior to launching the campaign."
