This estrildid finch is a resident breeding bird in drier regions of tropical Sub-Saharan Africa. Red-cheeked cordon-bleu has an estimated global extent of occurrence of 7,700,000 km2.

He used the French name Le Bengali and the Latin Bengalus. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the red-cheeked cordon-bleu. Linnaeus included a brief description, coined the binomial name Fringilla bengalus and cited Brisson's work.
