# Registration Session Expired

> The customer registration session has expired

## Cause

The verified-phone registration session has expired. Guile will not complete registration with that session token; no account was created from this call.

## Fix

Start a new phone challenge, verify the code, then complete registration with the new session token and a new idempotency key where required.

## Retry safety

Not retryable until the underlying state or request changes.

## Raised by

These operations can return this problem:

* [Complete customer registration](/api-reference/registration/complete-customer-registration)
