Clear communication keeps security teams safe, prepared, and professional. The 10 codes for security

system is the backbone of radio talk for security guards, officers, and dispatchers across Ontario. These

short codes let teams pass vital information quickly, whether they’re at a busy festival near Toronto’s

Yonge-Dundas Square or working a quiet night shift in a Mississauga mall. With Alpha Security Services,

learning these codes becomes second nature, helping every guard sound confident on the job.

10 Codes for Security: Speak Like a Pro in Ontario

Ontario is Canada’s most active province, known for its crowded events, busy shopping centres, and

expanding residential neighborhoods. Security guards need a fast, reliable way to talk—especially when

seconds matter. That’s where 10 codes for security help. Instead of long explanations, a guard can use

codes like “10-4” for “Message received” or “10-33” to signal an emergency to every team member

nearby.

Using 10 codes keeps conversations short and clear, even when there’s background noise or stress. This

is true whether you’re posted at a bustling sports venue or covering a quiet business in downtown

Ottawa. Alpha Security Services ensures every trainee learns these radio codes so Ontario’s guards stay

connected and ready.

What Security Guards Should Know About 10 Codes for Security

New security guards sometimes feel nervous about radio communication. The good news: most teams

use the same basic ten codes for security. Some of the most common codes are easy to remember and

used every day. “10-7” means “Out of Service” when ending a shift. “10-20” means “What is your

location?” Others, like “10-80” (pursuit in progress), are for rare but urgent moments.

Ontario security guards often practice these codes during training. It helps them respond faster to

dispatch and to each other on shift. Security officers sometimes add their own site-specific codes, but

the main set stays the same across much of Canada. Alpha Security Services teaches both universal 10

codes and the unique needs for guards working in cities like Hamilton, Windsor, or smaller communities.

How 10 Codes for Security Improve Real Work Scenarios

A night at the Toronto Eaton Centre can turn unpredictable. Loud music, crowds, and the buzz of events

mean guards must rely on quick radio calls. When a guard says “10-9,” the team knows to repeat the

last message. If a situation gets tense, “10-33” gets everyone’s attention right away.


With Alpha Security Services, Ontario guards learn why these codes matter. Imagine a sudden medical

emergency—a guard radios “10-52” for an ambulance, and help gets moving without confusion. In a

parking lot, “10-92” signals an illegally parked car, so the response is direct. Using the 10 codes for

security saves time, limits mistakes, and keeps everyone focused.

Alpha Security Services prepares guards with hands-on radio code drills. You’ll know what to say, how to

say it, and when to stay quiet. Teams who train together with these codes build trust and stay ready for

anything, from routine patrols in Scarborough to major events in downtown Toronto.
