505/515

What begins on social media as tough-looking edits and cryptic numbers such as 505 or 515 turns out to be anything but harmless. In reality it appears to be part of a broader subculture in which 505 and 515 function as symbols of origin, honour and group loyalty. Young people present these codes as a badge of pride, but also as a signal of "who belongs with whom".

In various cities we see that digital bravado sometimes ends in conflicts between groups, in which two groups in particular can end up facing each other:

1. Young people with a Syrian background (505/515)
- Use the numbers 505 or 515 as a symbol of origin, group identity and honour.
- Online, they show who belongs to their group and display pride, strength and status.
- Conflicts sometimes arise from provocations or threats by rival groups.
- Trend in Germany: some young people say explicitly that they are not afraid "because I am 505 and my cousins are from 515", thereby projecting a sense of collective protection and power.

2. Young people with a Chechen background
- Formed the main opposing side in the dynamic of online provocations and offline confrontations.
- In Vienna, conflicts have grown into violent incidents, including fights, use of knives and firearms, intimidation and loitering in the neighbourhood.
- Several young people were injured and police investigations have been launched.
- The group also uses symbolism and family ties to emphasise its own safety and status, but the rivalry with 505/515 can quickly escalate into a physical threat.

The conflict (often) begins online: status, videos, provocations, but can turn offline into fights, intimidation or loitering with heightened tensions. The aesthetic is recognisable: military music, weapon symbolism, masks, group formations, and the numbers 505 or 515 prominently in view. For many young people this feels like pride and recognition; for others it becomes a means of commanding respect or fuelling rivalry. Behind the scenes, themes such as honour, loyalty, protection of one's own group and feelings of marginalisation play an important role.

• Physical and emotional bonding: online and offline group formation creates loyalty. Young people feel stronger in a collective that understands them.
• Symbolism: numbers, colours, music and codes create a shared identity and a clear line between "us" and "them".
• Experience of insecurity: young people who carry experiences of discrimination, poverty or flight experience these groups as protection and something to hold on to.
• Honour and reputation: images of strength or threat are strongly rewarded on social media, increasing peer pressure to "join in".
• Escalation mechanisms: small online taunts, challenges or provocations can quickly grow into real conflicts between groups or neighbourhoods.
• Collective pride and protection: statements such as "I am 505 and my cousins are from 515" illustrate how group bonds and ties of family and friendship give young people a sense of invulnerability.

• Young people who suddenly use 505 or 515 in usernames, clothing, photos or videos.
• Online posts with violent language, weapons, threats or strongly hostile us-versus-them thinking.
• Masks, censored faces, military-looking poses or group photos with concealed identities.
• Young people who clearly set themselves against other groups (e.g. Syrian vs. Chechen, neighbourhoods or clans).
• Increased secrecy around gatherings, Telegram groups or night-time meeting places.
• Changes in behaviour: quicker to anger, more competitive, more focused on restoring honour or reputation.

Escalate to GEVAARLIJK (dangerous) in the event of violent language, weapons, threats or concrete rivalry between groups: in Vienna, similar rivalries have grown into fights and the use of knives and firearms, with injuries and ongoing police investigations. In the event of signals of weapons or incitement to violence/revenge: coordinate immediately with safety partners and the police.

• Acknowledge the appeal: pride, identity and group connection are healthy in themselves. Name what young people value before you discuss it as a risk.
• Be alert to language, symbolism and rivalry: small signals can be early indications of escalation.
• Encourage critical thinking: discuss peer pressure, sense of honour and reputation without being too moralising.
• Collaborate within the network: coordinate with school, the neighbourhood team (wijkteam), safety partners and parents when signals increase.
• Offer alternatives for status and connection: sport, culture, music, media production, mentoring programmes — activities in which young people build strength and pride without thinking in terms of enemies.
• Stay close: even after incidents or escalations, young people need support to return to healthy patterns.

In a group setting
- "What do those numbers actually mean to you?"
- "When does pride in your origins become a risk to others?"
- "How do images online affect how you behave offline?"
- "What happens when groups challenge each other and nobody wants to back down?"

One-to-one
- "What draws you to 505 or 515? What does it give you?"
- "Do you ever feel that others decide how you should behave?"
- "When does it feel safe in your group, and when doesn't it anymore?"
- "What would you do if someone was being pushed towards violence or revenge?"

Stay calm and non-judgemental. For many young people this is not necessarily crime, but a search for safety, recognition and identity. Rejection often pushes them deeper into the subculture.
