EasyPost has been highly reliable recently: StatusBird's independent monitoring recorded 100.0% availability and zero major incidents over the last 90 days.
Numbers alone do not tell you whether to worry, so this post also covers what actually breaks when EasyPost has problems and how to get warned early.
What is EasyPost?
EasyPost is a shipping API that gives developers a single integration to buy labels, fetch rates, verify addresses, track packages, and insure shipments across USPS, UPS, FedEx, DHL, and dozens of other carriers. E-commerce stores and shipping platforms use it behind the scenes to power checkout rates and warehouse label printing.

What happens to your store when EasyPost goes down?
An EasyPost outage cuts off every carrier at once for stores that route all shipping through its API, which makes it a bigger single point of failure than any one carrier. Label purchases fail, so fulfillment stalls across the whole warehouse, and checkout shipping rates error out or disappear if quoted live. Tracking webhooks stop flowing, so your store's tracking pages and shipment notifications go stale even though carriers keep delivering.
Typical symptoms during a EasyPost outage:
- Label purchase API calls fail or time out for every carrier, not just one
- Checkout shipping rates fail to load or show errors
- Address verification requests fail during checkout
- Tracking webhooks stop arriving and tracking pages go stale
- 5xx errors from api.easypost.com in your application logs

Frequently asked questions
EasyPost is down and I ship with multiple carriers. Why are all of them failing at once?
Because EasyPost is the single API layer between your store and every carrier, an EasyPost outage looks like a total carrier failure even though USPS, UPS, and FedEx themselves are fine. You can still buy labels directly from each carrier's own tools while the API is down.
Will I get charged for label purchases that errored out during the outage?
Requests that failed outright do not create labels, but requests that timed out after being accepted can. Once EasyPost recovers, list your recent shipments through the dashboard or API, match them against your orders, and refund any unused duplicate labels.
How this data is measured
StatusBird checks EasyPost's status every 2 minutes, around the clock, independently of the vendor. The availability figure counts major and critical outages only; minor degradation is excluded so numbers are not skewed by vendors that report small blips near-continuously. Grades run from A+ to F. See the live numbers on the EasyPost reliability page and current status on the EasyPost status page, or browse all 84 service grades.
Know before your customers do
StatusBird monitors EasyPost and 83 other services online stores depend on, plus your own storefront, every 2 minutes. When something goes down you get an SMS, email, or Slack alert with plain-English context, usually before the official status page catches up.
