In the guide Tell Google about localized versions of your page --> Supported language/region codes, Google says:
The value of the hreflang attribute identifies the language (in ISO 639-1 format) and optionally a region (in ISO 3166-1 Alpha 2 format) of an alternate URL. (The language need not be related to the region.) For example:
- de: German language content, independent of region
- en-GB: English language content, for GB users
- de-ES: German language content, for users in Spain
DZ is the entry for Algeria in ISO 3166. Therefore, your markup is correct for French for Algeria.
