Iquique — now a Chilean city — was briefly the site of a Peruvian bank branch during the 1870s, when the nitrate-rich Tarapacá region still belonged to Peru. The War of the Pacific (1879–1884) ended that arrangement decisively: Chilean forces occupied Iquique in 1879, and Peruvian banking operations in the city were effectively finished. Notes issued from this branch exist in a narrow window of time, which makes the Iquique suffix on any Banco Nacional del Perú note historically significant rather than merely a branch notation.

P#341 is among the scarcer provincial issues from this bank precisely because the occupation cut the normal circulation and redemption cycle short.
