+ * NIF, sometimes N.I.F. (Numéro d'Identification Fiscale, Algeria tax number).
+ *
+ * The NIF was adopted by the Algerian tax authorities on 2006, replacing the NIS
+ * number.
+ *
+ * The NIF applies to physical persons, legal persons, legal entities,
+ * administrative entities, local branches for foreign companies, associations,
+ * professional organisations, etc.
+ *
+ * The NIF consists of 15 digits, but sometimes it can be 20 digits long in order
+ * to represent branches or secondary establishments.
