How to fix Costco not working
Costco is up on our end, so if it won't work for you, the problem is most likely on your side. Work through these in order:
Your browser tries to reach costco.com over your own connection, right now. Nothing is sent to us or stored.
Reload the Costco item page
Reload the item page. Costco can stall on a weak connection, so switch from Wi-Fi to mobile data and open the item again from Search or your cart.
Open Costco in a private window
In Chrome, use the three-dot menu > New Incognito tab and sign in there. This skips stored cookies and extensions that can break the cart or checkout on your normal window; if the page loads, clear site data for the store in Chrome settings.
Clear the Costco app cache
On Android, open Settings > Apps > Costco > Storage > Clear cache. Then reopen the app and sign in. On iPhone, delete the app and install it again from the App Store because iOS has no per-app cache button.
Update and reinstall the app
Update the app from Google Play or the App Store. Sign out from the Account tab, sign back in, and retry checkout. If payment still fails, delete and reinstall the app, then sign in again; keep the item in your cart so you can retry without rebuilding the order.
While Costco is down: what to use instead
- Costco website Try the website if the app won't load; it can handle order tracking and account changes from a browser.
- Costco help centre Use the help centre when an order or membership problem needs a person and the app isn't working.
- Physical membership card Show your physical membership card at the door or register if the app won't load the digital one.
- Warehouse membership counter Go to the membership counter at a warehouse if you need a membership issue handled in person.

What happens when Costco goes down
Costco is a membership warehouse retailer with a website and app for shopping and account tasks. Members and small businesses rely on it for bulk supplies and household goods, so an outage interrupts browsing and checkout, and it can block order or membership access.
When the service has trouble, product pages and search often fail before checkout; you may get a blank page, a spinner, or a message that the page cannot load. Sign-in and membership account pages can reject a password or hang, and checkout may stall at payment or order review. Order history and tracking may lag behind or return an error, while the app can drop you back to sign-in mid-session. Problems are often regional or tied to one platform, and other parts of the service keep working.

How we track Costco
The status on this page comes from user-submitted problem reports for Costco, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for Costco, so a few complaints on a quiet day don't trigger anything, but a sudden jump well above normal does.
When reports climb well above normal, the status here changes to partial outage or major outage and the chart moves with it. Costco doesn't publish a public status page that we know of, so user reports are often the quickest sign that something is wrong on their side.
