Nod Ardal Dim Galw Diwahoddiad yw amddiffyn trigolion agored i niwed a lleihau nifer yr achosion o drosedd ar stepen y drws. Rydym yn ceisio cynyddu nifer yr ardaloedd lle nad oes croeso i alwyr stepen y drws. Eu bwriad yw rhoi’r hyder i drigolion a chymunedau lleol ddweud “na” i werthwyr diwahoddiad neu rybuddio masnachwyr twyllodrus a galwyr diwahoddiad bod rhywun yn eu gwylio.
No Cold Caller Zones are aimed at protecting vulnerable residents and reduce the number of doorstep crime incidents. Our aim is to Increase the number of areas in which doorstep callers are not welcome. They are intended to give local residents and communities the confidence to say "no" to uninvited salespeople or to warn rogue traders and cold-callers they are being watched.
