# E12062 — SMSKeywordRuleAlreadyExists

A keyword rule for this operation already exists at this scope.

- **HTTP status**: `409`
- **Type**: `conflict_error`
- **Name**: `SMSKeywordRuleAlreadyExists`

## What to do

Update the existing rule instead of creating a second one. Opt-out, opt-in and help allow one rule per country, language and number, because two would cover the same keywords with no way to tell which wins. Rules with the `custom` operation have no such limit.
