The Costco App Complete Guide 2026: Every Feature, Every Trick and Why Most Members Only Use 20% of It

The Costco app is the most underused tool in the Costco member ecosystem. Most members who have it use it for one or two things — checking the current Member Savings coupon book, or viewing their digital membership card when they have forgotten their physical card. A small, more commercially savvy group of members uses it as a complete shopping and membership management platform that handles everything from prescription refills to custom cake orders to contactless payment at the warehouse register.

The gap between what the app can do and what most members use it for is significant. This guide closes that gap — covering every feature the Costco app includes in 2026, the specific setups that unlock the most useful capabilities, and the handful of features that most members have genuinely never discovered despite carrying the app on their phone for years.

Feature 1: The Digital Membership Card — The App's Most Important Function

The digital membership card is the reason to download the Costco app if no other feature convinces you. It is a complete digital replacement for the physical membership card — displaying your membership number, a scannable QR code, and your membership photo in a format that works at the warehouse entrance scanner, at the pharmacy counter, at the optical center, at the hearing center, at the tire center, and at the gas station pump.

It works without wifi. Once the digital card is set up and your membership is verified, the card is available offline — meaning you do not need a cell signal or wifi connection to access it at the warehouse entrance. This is a critical practical detail for members who have spotty coverage inside large warehouse spaces.

The auto-launch feature is the most commercially significant digital card capability that most members have never enabled. With your location turned on and set to Always in your phone settings, the digital membership card automatically pops up on your phone's lock screen when you arrive at a Costco warehouse. You do not need to open the app, navigate to the card section, or unlock your phone.

The card appears on the lock screen, ready to scan, as you approach the entrance.

The setup process: Open the Costco app → tap the Account icon → look for "Access your Digital Membership Card from your lock screen" → tap Set Up Now → enable Location (set to Always), Notifications, and Live Activities in your phone settings.

Once configured, the auto-launch experience eliminates the specific friction point that slows every line at every Costco entrance: the member who arrives, discovers they need their card, and then spends thirty seconds unlocking their phone, finding the app, and navigating to the card while people wait behind them.

Adding your Visa card to the digital membership card:

You can link your Costco Anywhere Visa Card (or any single Visa card) to your digital membership card in the app. Once linked, you can use your phone for contactless payment at warehouse registers — a single tap at the terminal completes both the membership scan and the payment simultaneously.

To add: open the digital card in the app → tap Add Visa Card → enter card information → verify. Once added, the linked Visa card works at warehouse registers, gas stations, pharmacies, and the tire center. It does not work at the food court — food court payment requires a separate card transaction.

Feature 2: The Member Savings Coupon Book — In Your Pocket Before It Arrives in Your Mailbox

The current Member Savings book is fully accessible in the app — updated the moment each new savings period launches, typically before the physical book arrives in most members' mailboxes.

The app's Member Savings section shows every featured item with its discount amount, the product description, the valid period dates, and — for many items — the ability to add the item directly to your digital shopping list.

The strategic value of the in-app coupon book: checking it before every warehouse visit takes three to five minutes and consistently identifies four to eight items on your shopping list that are currently discounted. Members who check it in the car before entering capture coupon savings they would miss by discovering the discount after purchase.

The price adjustment connection: checking the current book against recent purchases — visible in the app's Order History and Purchases section — takes ninety seconds and identifies any price adjustment claims from items purchased in the past 30 days that now appear in the Member Savings book at a lower price.

Feature 3: Warehouse Inventory and Pricing — The Shopping Intelligence Layer Most Members Miss

The Costco app includes a warehouse inventory and pricing feature that allows members to check whether specific items are available at their home warehouse before making the trip. The inventory display is not real-time with pinpoint accuracy — the app acknowledges that inventory information may not be 100 percent current — but it is accurate enough to avoid the frustration of a specific-item trip that ends with the item being out of stock.

The app also shows pricing for specific items, allowing pre-trip price research. For members comparing whether a specific product is worth buying at Costco versus an alternative source, checking the app before leaving home eliminates the need to make a warehouse visit to verify pricing.

The warehouse locator within the app includes location-specific details: hours, phone number, services available (pharmacy, optical, hearing center, tire center, gas station), and the current gas price at that specific location.

The current local gas price: One of the most consistently useful single data points in the app — the real-time gas price at your home warehouse, updated throughout the day as Costco adjusts its pump pricing to reflect wholesale market movements. Members who check the app before deciding whether to make a warehouse detour for gas can make a data-driven decision rather than guessing whether the savings are sufficient to justify the route.

Feature 4: The Digital Shopping List — Replace the Paper List

The app includes a digital shopping list that allows members to add items from the Member Savings section, search for specific products and add them from the product catalog, and manually add items by name. The list is accessible offline, syncs across devices, and is organized by the categories that match Costco's warehouse layout.

For members who currently shop from a handwritten or notes-app list, the Costco digital shopping list adds specific product information — item numbers, current prices, Member Savings discounts — that a handwritten list cannot include.

The most efficient pre-trip workflow in 2026: review Member Savings in the app → add discounted items that match your planned purchases to the list → add any additional needed items → arrive at the warehouse with a complete, organized, discount-aware shopping list.

Feature 5: Pharmacy Prescription Refills and Management

The Costco app includes a full pharmacy management suite — one of the most useful features for members who regularly fill prescriptions at Costco Pharmacy and one of the most consistently overlooked.

Refill prescriptions through the app: select the prescription you want to refill from your pharmacy account, choose the pickup location, and submit. The pharmacy receives the refill request and notifies you when the prescription is ready. No phone call to the pharmacy. No in-person request. A three-tap process.

Manage family accounts through the app: members who manage prescriptions for household dependents — children, elderly parents — can add family members to the pharmacy account and manage their prescriptions alongside their own in the same app interface.

Medication reminders: the app supports setting dose reminders for medications — a genuinely useful health management tool that extends the app's utility beyond the commercial shopping use cases.

View medication history: the full prescription history tied to your Costco Pharmacy account is visible in the app, providing a convenient reference for any member who needs to review their prescription record without calling the pharmacy.

Feature 6: Custom Bakery Orders — The Feature Nobody Talks About

This is the app feature that generates the most surprised reactions from members who discover it for the first time: you can order custom cakes and cookie trays through the Costco app.

Costco's bakery produces custom half-sheet cakes for events — the same $24.99 half-sheet that serves 48 people and has made Costco one of the most popular sources of celebration cakes in America.

Custom cakes require advance ordering — they are not available same-day. The app provides the ordering interface: select the cake size, choose the flavor and filling, specify the inscription text, select a pickup date, and submit. The bakery receives the order and prepares the cake for the requested pickup time.

Cookie trays — the large-format cookie trays that make Costco's baked goods practical for group events and office gatherings — can also be ordered through the app with advance notice.

For members who regularly use Costco's bakery for events — birthdays, celebrations, office gatherings — the app ordering capability eliminates the in-person deli counter order that previously required a warehouse visit specifically to place the order.

Feature 7: Same-Day Delivery Integration

The app connects to Costco's same-day delivery service powered by Instacart, allowing members to place delivery orders directly from the app. The integration shows current warehouse inventory for deliverable items, displays the free delivery threshold ($75), and allows selection of delivery windows from as fast as one hour.

For Executive members, the $10 monthly credit for orders of $150 or more is visible and trackable in the app's delivery section — confirming whether the current month's credit has been used.

Feature 8: Costco Travel — Vacation Booking in the App

The Costco Travel section of the app provides access to the full Costco Travel vacation package inventory — Hawaii, Mexico, Caribbean, Europe, cruises, and rental cars — with member pricing applied automatically and the current promotional deals (Shop Card offers, More Stay Less Pay bundles) visible in the app interface.

For the Executive member who uses Costco Travel regularly and wants to monitor the current Hot Buys before they sell out, the app's Travel section provides the fastest access to the promotional inventory — faster than navigating Costco.com's full website on a mobile browser.

Feature 9: Order History and Purchase Tracking

Every warehouse purchase, Costco.com purchase, and pharmacy transaction tied to your membership account is visible in the app's Order History and Purchases section. This complete purchase history serves several commercially valuable functions:

Price adjustment research: compare recent warehouse purchases against current Member Savings items to identify adjustment claims.

Return documentation: if a return is needed, the purchase record in the app eliminates the need for a paper receipt — the transaction record serves as the documentation that membership services uses to process the return.

Spending tracking: for members tracking their annual Costco spending to evaluate whether the Executive upgrade is worth the cost, the purchase history provides the data for the calculation.

Executive reward tracking: the app displays the current year-to-date Executive reward balance — so members can see in real time how their 2 percent accumulation is progressing toward the February certificate.

Feature 10: Passwordless Sign-In — The 2026 App Update That Removes Friction

In 2026, Costco updated the app to support passwordless sign-in — allowing members to access the app using biometric authentication (fingerprint or Face ID) rather than entering a password. This update specifically addressed the friction that password-based login created for members of the Costco demographic who found the password management step a barrier to regular app use.

The passwordless login makes the app significantly more accessible to members who previously found logging in every few visits too cumbersome and simply returned to carrying the physical card.

Once biometric login is configured, app access is as simple as pointing your phone at your face or pressing your thumb — no password, no email address, no forgotten credential.

The Setup Checklist: Everything to Configure Before Your Next Visit

For members who have the app but have not maximized its configuration:

Enable the digital card auto-launch (location always on, Live Activities enabled). Link your Visa card to the digital membership card for contactless payment. Set your home warehouse as default.

Enable pharmacy account and add household members. Set up medication reminders for any current prescriptions. Configure passwordless biometric login. Enable notifications for Member Savings updates and warehouse announcements. Save your digital shopping list with recurring staples.

For members who do not yet have the app: download from the App Store (iOS) or Google Play (Android), create a Costco.com account if you do not already have one, enter your membership number and verify your membership, and set up the digital card in the first five minutes.

The entire setup process — downloading the app, creating an account, verifying membership, enabling the digital card auto-launch, and linking a Visa card — takes approximately fifteen minutes and eliminates at least five recurring friction points from every subsequent warehouse visit.

At MOJO Sales & Branding, we understand every dimension of the Costco member experience — from the app that makes every visit more efficient to the roadshow brands that create the discovery moments that make the warehouse worth visiting every week.
