The country code in some Zimbabwean passports were not printed in accordance with the
ISO code for
Zimbabwe. The country code in these passports is listed as ZIM when it should otherwise be ZWE; this has led to frustrating encounters for Zimbabweans with airline, immigration, and border control officials. This error has often led to officials suspecting such passports to be fake. When the passport's
MRZ is scanned, the immigration and checking systems fail to recognise the country code ZIM. Airlines have issued circulars to their staff and published information on their websites highlighting this issue. ==Visa requirements==
