Discover Decline Code 87: Network Unavailable

What Discover Decline Code 87 Means

Discover decline code 87 (Network Unavailable) indicates that the network required to process the transaction was unavailable.

Where the Response May Come From

Code 87 means the network needed to authorize the transaction was temporarily unavailable. It is an infrastructure condition rather than an account problem, so the processor response and a later attempt are the reference.

Common Reasons for This Response

Common causes include temporary outages or connectivity problems on the processing network.

Should the Merchant Retry the Payment?

A retry after a short wait often succeeds once network availability is restored; repeated immediate retries add little during an outage.

Recommended Merchant Action

Wait briefly and retry, and if code 87 persists, check network status with your processor before continuing to reattempt.

What to Tell the Customer

Let the customer know a temporary network issue occurred and ask them to try again shortly.

How to Reduce Similar Payment Failures

Monitoring code 87 frequency helps distinguish brief network blips from broader outages so you can pause and resume processing sensibly.

Important Limitations

Decline-code meanings vary by processor, gateway, and payment environment, and issuers do not always disclose the specific reason behind a response. The retry classification on this page is Payment Defender editorial guidance, not an official network rule. Merchants should confirm handling with their processor or gateway.
