The Give With Care campaign will echo a scheme that ran in England in 2009, which encouraged people to keep an eye out for fake charity clothing collection sacks.
Details of the Scotland campaign were discussed at a meeting on charity bag fraud and theft last week convened by the IoF and the FRSB.
Gregor McNie, Scotland manager for the IoF, told Third Sector after the meeting that letters would be sent to MSPs and the local press in Scotland to ask them to raise awareness of charity bag fraud and theft, and leaflets would be posted through doors to encourage people to be wary of bogus collectors.
"It’s a problem that’s been reported to us by a lot of our members, so we’ve reacted to that," he said. "We’ve also recently had a meeting with Scottish police chiefs to discuss the issues, and they’re supportive of the campaign."
The leaflets say: "Your contributions are invaluable to good causes, but bogus collectors sometimes take donations from where they’re needed most."
They also tell people to look out for a charity number and the FRSB logo on charity collections bags.
McNie said leaflets would be posted to 60,000 households in Scotland by the collection agency Clothes Aid in areas where collections usually took place.
He did not know how long the campaign would run for, but said it would be kept under review to see if it was working.
The 2009 campaign in England was supported by what was then Office of the Third Sector.
Delegates at the meeting also called for the campaign to be repeated in England. Asked whether this would be possible, Nick Hurd, the Minister for Civil Society, who gave a presentation, said: "If people can make a robust case for that, then my mind is open."
