# E23xxx — Realtime

Error codes in the `E23xxx` range that the public Bird API returns. Each code links to its own page (the page its `doc_url` points at) with the cause and what to do. Retired codes stay listed; they are never renamed or reused.

| Code                                | Name                             | Status | Message                                                                  |
