# Cannot revise address region or city

You're trying to revise a transaction to update the city or region, but these fields are already set and can't be changed.

---

## Example

```json
{
  "error": {
    "type": "request_error",
    "code": "transaction_address_region_or_city_already_set",
    "detail": "Address city or region can't be revised if already present.",
    "documentation_url": "https://developer.paddle.com/errors/transactions/transaction_address_region_or_city_already_set"
  },
  "meta": {
    "request_id": "00000000-0000-0000-0000-000000000000"
  }
}
```

## Details

| Attribute | Value |
| --- | --- |
| Status code | 400 |
| Error code | `transaction_address_region_or_city_already_set` |
| Error message | Address city or region can't be revised if already present. |

## Common causes

- The transaction you are trying to revise has an address with city or region already set. These fields can be added if not set, but can't be changed otherwise.

## Common solutions

- If you're revising other details, send your request again without including address city and region.
