How to Prevent Shoplifting: A Guide for Store Managers and Owners

The shoplifting guide published by the ASU Center for Problem-Oriented Policing, written by Ronald V. Clarke and Gohar Petrossian (second edition, 2013), describes shoplifting as one of the least detected and reported crimes and notes that only about one in 150 incidents leads to the offender’s apprehension and subsequent police action. Because so few thefts end in an arrest, the most dependable gains come from changing the store itself: what can be reached, what can be seen and where staff are positioned.

Recent industry data shows progress alongside new pressure. In The Impact of Retail Theft & Violence 2026, the National Retail Federation (NRF) and the Loss Prevention Research Council (LPRC) reported that surveyed retailers saw a 12.4% decrease in shoplifting incidents in 2025 compared with 2024. The same study found that 40% of respondents reported higher rates of organized retail crime incidents and 50% reported a rise in repeat offenders. More figures are collected on the retail theft statistics page.

The Framework Behind Effective Prevention

Situational crime prevention starts from a practical premise: offenders respond to the opportunities a setting presents. The Center for Problem-Oriented Policing describes five ways to change a situation, expanded into the Twenty-Five Techniques of Situational Prevention. Each has a direct retail equivalent.

The LPRC organizes its research along similar lines, around three zones of influence: affecting an offender’s choices through signage, lighting and cameras; detecting threats through technology, personnel and systems; and connecting what is learned from an incident with law enforcement, community organizations and other retailers.

Opportunistic Theft and Organized Theft

The Clarke and Petrossian guide separates petty shoplifters, who differ little from a store’s regular customers, from determined thieves who steal regularly and sell through fences, and from organized groups whose members divide the work among boosters, handlers and those who manage transport and logistics. The distinction matters because opportunistic and organized theft respond to different measures.

Opportunistic theft responds well to good layout, attentive service and basic merchandise protection. Organized crews plan around those measures. The guide notes that sophisticated offenders know how to defeat electronic article surveillance and that professional shoplifters are increasingly resorting to violence. NRF’s 2026 study concludes that retail theft still indicates theft for greed rather than need. Organized activity calls for stronger documentation, coordination with police and, often, trained security personnel. State laws that treat it as a separate offense are summarized on the organized retail crime laws by state page.

Store Layout and Sightlines

The guide identifies aisles that staff cannot easily survey from one end, high displays that conceal shoppers, and goods near entrances as risk factors. Its layout recommendations include:

• Fewer exits, blind corners and recesses
• Lower displays and clear aisle sightlines
• Good, even lighting
• Carefully placed mirrors
• Less clutter and obstruction
• Goods placed away from entrances and exits
• Less crowding near high-risk displays
• Faster checkout to reduce congestion and waiting

A useful test is to stand at each register and service point and note which parts of the floor cannot be seen. Those areas should hold lower-risk merchandise or receive more frequent staff presence.

Protecting Merchandise Without Losing Sales

Theft concentrates on what the guide calls hot products, items that are concealable, removable, available, valuable, enjoyable and disposable (CRAVED). Recommended measures include keeping high-value items in locked displays or securing them with cable locks and security hangers, moving hot products into higher-security zones with more staff attention, electronic article surveillance and ink tags.

Each of these measures has a cost. The guide observes that abandoning self-service would be impossibly expensive for stores, that shoppers who cannot inspect goods at leisure may not buy them, and that some security practices are unpopular with staff and customers alike. A sound approach applies the heaviest protection only to the items with a documented loss history, makes sure a locked case can be opened quickly by staff on the floor, and reviews the list of protected items as loss data changes.

Greeting and Engaging Shoppers

Attentive service is among the least expensive deterrents available. The guide recommends that stores train staff to be attentive to customers and alert for thieves, and hire enough staff to oversee goods and customers properly. It also quotes a retail asset protection executive’s observation that approaching a customer and asking whether they need help tends to inhibit criminal behavior. In practice, this means acknowledging every shopper at the door, assigning associates to zones rather than leaving them behind registers, and returning to shoppers who linger in high-risk areas. Engagement should be offered to every customer in the same way: it is good service, and it keeps attention on behavior rather than appearance.

High-Risk Times

According to the guide, most shoplifting occurs when stores are busiest, with the majority of incidents late in the week, between Wednesday and Saturday, and much of it in the periods before Easter, summer and Christmas. Because juveniles commit much shoplifting, high-risk times also include late mornings on non-school days and afternoons into the evening. Managers should compare their own incident records against the staffing schedule. Where losses cluster in periods of thin coverage, adjusting breaks and shift overlaps is a low-cost first step.

Fitting Rooms

The guide lists changing rooms among the store features that raise theft risk. It recommends clear rules for their use and placing retail associates in changing-room stations. Common practices include counting items in and out, keeping unattended rooms locked, and clearing left-behind merchandise and empty hangers promptly so that missing items are noticed the same day.

Self-Checkout

The guide notes that self-scan presents new opportunities for shoplifting despite security features such as transaction cameras and irregularity detection software, for example scanning one item and taking more of the same item without paying for them. A 2019 LPRC research highlight on self-checkout theft, based on offender interviews, reported that public view monitors deter some people and that less attention from employees is among the factors that make offenders feel it is easier to get away with theft. Self-checkout areas work best with a dedicated attendant and a clear line of sight from the attendant’s position.

Staff Training and a Safety-First Response

As a matter of policy, store employees should not chase, block, grab or physically confront a suspected shoplifter. The risk to people outweighs the value of the merchandise. NRF’s 2025 study reported that threats or acts of violence during shoplifting or theft events increased 17% in 2024 compared with 2023 among surveyed retailers, and the Clarke and Petrossian guide notes that mistaken apprehensions can result in lawsuits.

Training should give employees a clear and limited role: offer service, observe, note descriptions and direction of travel, notify the manager and call 911 when anyone’s safety is at risk. NRF’s 2026 study found that, to address workplace violence, retailers are investing in management training (72%) and employee training (65%), among other measures. Retailers in New York should also review the state’s Retail Worker Safety Act.

Documenting Incidents

The guide cautions that police records rarely allow shoplifting offenses to be identified among other reported thefts, so a store’s own records are often the only reliable picture of its losses. Each incident report should capture the date and time, location in the store, items and retail value, a factual description of the people and their actions, direction of travel and any vehicle, whether video was preserved, and the police report number. Consistent records reveal patterns by time, department and product, and they allow separate incidents to be linked when a case is built.

Working With Police

The guide is direct on this point: police can do little on their own to prevent shoplifting, and retailers themselves have to act. Police are most useful when stores report consistently and provide organized evidence. Because organized groups rarely operate within one jurisdiction, the guide also points to task forces and to same-day early warning systems through which merchants notify one another about mobile groups of organized shoplifters. Managers should know the local precinct or district contact and join any retail or business crime network in the area.

When Uniformed Officers Help

The guide acknowledges that little is known from research about the effectiveness of uniformed security guards. It adds that guards who move around, creating an active, visible presence, are likely to be more effective, and that poor guards have no effect on shoplifting. Officer quality and post design matter as much as presence.

Uniformed officers tend to add the most value when incident records show repeated losses, when organized groups are active in the area, when a store carries high-value goods, when employees have faced threats, and during peak trading periods. In most retail settings, the post should be built around observation, reporting and deterrence rather than apprehension. At McCray, officers complete a five-stage screening process and tier-based training before assignment, including de-escalation and, for retail posts, organized retail crime recognition. Supervisors make unannounced site visits, and the McCray Operations Desk answers 24/7/365. Incidents are documented on scene, time-stamped and GPS-verified.

Common Questions

What is the most effective way to prevent shoplifting?

No single measure works alone. The research supports a combination of clear sightlines, attentive staff, protection targeted at high-risk products and consistent incident records, adjusted as the store’s own loss data changes.

Should store employees try to stop a shoplifter?

No. Employees should observe, record details, notify a manager and call 911 when safety is at risk. Physical confrontation exposes staff and customers to injury and the business to liability.

When does most shoplifting happen?

The ASU Center for Problem-Oriented Policing guide reports that most shoplifting occurs when stores are busiest, mostly between Wednesday and Saturday, with seasonal peaks before Easter, summer and Christmas.

Do security guards reduce shoplifting?

Research is limited. The guide suggests that guards who move around and maintain an active, visible presence are likely to be more effective, and that poor guards have no effect on shoplifting.

Does locking up merchandise hurt sales?

It can. Shoppers who cannot inspect goods freely may not buy them. Locking should be limited to items with a documented loss history, with staff ready to open cases quickly.

What should a store do after a shoplifting incident?

Confirm everyone is safe, preserve video, complete a written report the same day and file a police report. Consistent records allow related incidents to be linked later.
