# `register_unavailable`: the register is not installed on this server

The register that would answer has not been synced here, so the lookup was not attempted.

- Appears in: `reason`
- Billing: Free. An identifier no register could answer for never costs a credit.

Registers are bulk files synced on a schedule. Until one has been installed, every identifier it would answer reports this rather than reporting that the entity does not exist.

Absence of data is never reported as absence of the company. Free, and never cached, so the next lookup answers as soon as the register lands.

**What to do.** Check /status, which lists every dataset this server holds with the date of its copy.

```json
{
    "identifier": "5493001KJTIIGC8Y1R12",
    "identifier_type": "lei",
    "found": false,
    "reason": "register_unavailable"
}
```
