Can You Use Scan & Go at Costco? A Practical Guide

What Scan & Go is at Costco

Scan & Go at Costco is a mobile checkout option that lets you scan items with the Costco app as you shop, pay in-app, and exit through a dedicated gate. According to Scanner Check, this capability is intended to speed up the in-store experience for busy shoppers while preserving cart integrity and price accuracy. Availability varies by store, region, and whether the location supports the Scan & Go workflow. The program covers most everyday groceries, household items, and bulk products, but certain categories may be restricted at the store's discretion or due to local regulations. Before you visit, ensure your app is updated to the latest version and your device is compatible with Costco's scanner interface. Not every item may be eligible for Scan & Go; alcohol and some restricted items may require standard checkout.

Can you use Scan & Go at Costco? Availability & eligibility

The practical answer is yes in many Costco locations for members with the official Costco app. The functionality is typically available at participating warehouses, and you can see in-app notices which stores support it. Members should verify store eligibility in the app before arriving; some locations may have phased rollouts or temporary outages. Alcohol, cigarettes, or certain high-value items may be excluded from the Scan & Go flow. The app may also require minimum versions and device compatibility (iOS/Android). Some regions may require a screen at the door for identity verification; be prepared for occasional adjustments during busy periods.

How to start: the in-app setup

To begin, open the Costco app and sign in with your member credentials. Navigate to the Scan & Go section and enable the feature if prompted. Grant the app permissions it requests (camera, notifications, and location if asked). Once enabled, the in-app camera will scan barcodes, and your cart will appear in real time. If you cannot locate Scan & Go, update the app or check the store's aisles signage for availability. Once set up, you’re ready to scan as you shop.

In-store flow: scanning, bagging, and exit

As you move through the aisles, press the scan button and scan each item as you place it in your cart. The app displays item name, price, and any applicable discounts. Bag the items or place them in your cart in a way that makes the digital list match what you physically carry. When you’re ready to pay, review the cart in-app, apply any coupons or promotions, and complete payment securely in-app. At the exit, use the designated Scan & Go gate or present a digital receipt to staff for verification and exit.

Limitations and caveats

Scan & Go is not guaranteed at every Costco; store participation may vary day-to-day. Some items might be non-eligible due to size, location, or regulatory restrictions. Alcohol and tobacco policies may require traditional checkout in certain jurisdictions. Returns and exchanges may have different procedures when purchased through Scan & Go, so review receipt data in the app and keep a digital copy. Always have a backup payment method if the app encounters issues.

Security and privacy considerations

Using Scan & Go involves transmitting purchase data and your membership identity through the Costco app. Ensure your phone is secured with a passcode or biometric lock and keep the app updated to minimize vulnerabilities. Costco and the app provider typically use encryption in transit and at rest. Be mindful of public Wi‑Fi when performing payments; prefer a secure network or cellular data. If your device is lost, report it and remove access to the Costco app quickly.

Tips for a smooth Scan & Go experience

• Update the Costco app to the latest version before shopping.
• Make sure your membership is active and linked in the app.
• Use a stable internet connection and keep your phone charged.
• Scan items as you add them to your cart to minimize miscounts.
• Review the cart often for pricing, promotions, and discounts.
• If you see a mismatch, use the app’s help feature or contact staff.

Common mistakes to avoid

• Scanning items after you bag them; this can cause price misreads.
• Skipping verification of eligibility for the store you’re in.
• Relying on the app in areas with poor connectivity; offline scanning can fail.
• Forgetting to pay in-app before exiting; ensure payment completes.
• Not updating the app or device permissions; this can block camera access.
