Your security guard license (guard card) is a legal requirement in most states — list it first with your state and expiration date. Follow with any additional credentials: armed permit, CPR/AED certification, First Aid, or facility-specific clearances. Employers screening security candidates often filter by certification status before reading anything else.

Security guard roles vary enormously in scope — from a single retail store to a multi-building corporate campus. Give employers context: state the facility type, square footage, number of entry points monitored, and patrol frequency. This tells a potential employer whether your experience matches the complexity of their site.

The most valuable thing on a security guard resume is a proven track record of incident handling. List specific incident types you've responded to — theft, trespassing, medical emergencies, disturbances — and note the outcomes. Even a clean record ('zero incidents during tenure') is a metric worth stating explicitly.
