# `missing_postal_code`: the country requires a postcode and none was given

The operator treats the postal code as mandatory and the address does not carry one.

- Appears in: `reason`
- Billing: Free. An address that cannot stand as written never costs a credit.

Where the postcode is required it is what sorts the item, so an address without one is incomplete however precise the rest of it is.

Spaw takes the postcode out of the line that carries it, from whichever end that country writes it, or reads the `postal_code` field. A postcode typed into the town line in an unusual position can be missed: send it separately when you hold it separately.

**What to do.** Fill in `postal_code`. A directory-covered country can supply it from the rest of the address only where a licensed address-list partner is configured; Spaw never invents one.

```json
{
    "valid": false,
    "reason": "missing_postal_code",
    "country": "GB",
    "postal_code": null,
    "locality": "London",
    "risk_score": null
}
```
