It is not safe for children to go trick or treating without adult supervision, according to advice issued by Northumbria Police.
Any children seen out and about by themselves could be escorted home and their parents spoken to by officers.
The custom of Penny For The Guy also comes with a safety warning, with officers concerned about youngsters hanging around outside pubs and clubs asking strangers for cash.
Northumbria Police Assistant Chief Constable Greg Vant said:"Responsible parents know they need to plan ahead for Halloween and arrange visits for their youngsters at the homes of friends and family.
"Young children alone out in the dark without an adult can be very vulnerable.
"Parents should realise that it can be quite frightening for vulnerable and elderly residents to have a series of callers coming to their door at night and asking for sweets.
"This is particularly unwelcome if they don't know the youngsters, or if they are persistent and become unpleasant if the householder has nothing to offer them."
Police are asking the public, shopkeepers and the licensees to contact them if they see children in circumstances that makes them vulnerable.
Officers will take children home if necessary and speak to the parents about their child's safety.
Anyone with any concerns about crime or disorder where they live can contact their Neighbourhood Policing Team on 101 ext 69191.
