# Locales, Languages and Currencies

> How to configure locales to segment your referral campaigns by customer region, language, and currency.

A locale defines the customer's language, region, and currency. For example, the locale for UK English using GBP is `en_GB`.

With Mention Me, you can deliver specific campaigns or referral offers by locale, passed via your integration (JavaScript tags for websites, API calls for apps) using a set format.

You can configure locales within your campaign's triggering or qualifying rules.

## How to segment customers by locale

Prioritise key regions/locales based on volume or value. If your referral programme offers third-party rewards like Amazon vouchers, ensure those providers cover the relevant locales. Your Client Manager can help define an effective segmentation strategy.

### Different language and currency

Pass the correct locale via tags or API calls:

* British Campaign: `en_GB`
* French Campaign: `fr_FR`
* Spanish Campaign: `es_ES`
* German Campaign: `de_DE`

### Same language, different currency

Serve offers to regions using the same language but different currencies by targeting relevant locales.

Example: English-language campaigns in the UK (GBP) and the US (USD) using `en_GB` and `en_US`.

### Same region and currency, different language

Create localised campaigns for users in a region who select different languages on your site.

Example: Target both `es_ES` (Spanish) and `en_ES` (English) customers within Spain (EUR).

### Group regions by the same language and currency

Target multiple regions under a shared locale if they use the same language and currency.

Example: Use `en_EU` for all English-speaking users in Eurozone countries.

### Group regions with shared language and generic offers

Useful for smaller or less-active markets. Serve a general campaign across several regions using one shared locale with a non-market-specific offer (like a percentage discount or gift with purchase).

If using discount codes, ensure they're valid across all regions. This setup does not support fixed-amount offers (e.g. £10 off) or third-party vouchers. It limits your ability to run A/B tests across locales. Contact your Client Manager for consultation.

## Locale format

The format must follow:

* <a href="https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes" target="_blank" rel="noopener noreferrer">ISO 639-1 language code</a> + underscore (`_`)
* <a href="https://en.wikipedia.org/wiki/ISO_3166-1#Current_codes" target="_blank" rel="noopener noreferrer">ISO 3166-1 alpha-2 country code</a>

Examples:

* `fr_FR` = French / France (EUR)
* `en_IE` = English / Ireland (EUR)
* `en_GB` = English / UK (GBP)

Your active locales will be listed in your order form. Contact your Client Manager to add more.
