The public are being urged to store a free helpline number in their phones this winter.
The number - 0800 027 7466 - could mean people sleeping rough or at risk getting the help they need.
If you see someone in need of help and you don’t know where to turn, the number will put you through to people who can assist.
Get Help Glasgow is a new campaign raising awareness of what services are available to vulnerable people on the streets.
The inaugural campaign has been launched by the Glasgow Alliance to End Homelessness.
People are more at risk of presenting as homeless during the winter months.
Get Help Glasgow is informing the public of tangible actions they can take if they, or someone they know, is sleeping on the streets to get immediate support.
It is also raising awareness of what help and further advice are available that can prevent someone from becoming homeless in the first place.
Alliance director Mark Kelvin said: "Glasgow is a compassionate and caring city, but it hasn’t always been clear where to look for help or know what to do when someone finds themselves, or someone they know, sleeping on the street.
“We have a huge number of organisations and services working across Glasgow ready to support people.
“Whether that’s information and advice on services in the community or practical support for things like food and money advice, all of which is now visible in one place at Get Help Glasgow.
“We’re encouraging people to save the Rough Sleepers and Vulnerable People (RSVP) helpline number in their phone this winter.
“So if somebody is rough sleeping and needs immediate support, the team can get them the right help."
Jim McBride is head of Adult Services (Criminal Justice and Homelessness) at Glasgow City Health and Social Care Partnership.
He said: "Nobody needs to sleep on the streets in Glasgow, so it’s vital that people get the support they need as soon as possible.

Get Help Glasgow encourages people to call the Rough Sleepers and Vulnerable People (RSVP) free helpline on 0800 027 7466.
The helpline is managed by Simon Community Scotland on behalf of Glasgow City Council.
