Note that the official URL for Ethiopian e-visas is the government website www.evisa.gov.et.
It now carries a warning: “We have come to know that there are some fraud websites which have similar look and feel to our official visa website. Please note that the Ethiopian Government doesn’t have any agreement with the owners of those websites. Any visa application submitted or payment made through these websites is not acceptable. Please do not submit visa application on http://www.ethiopiavisa.com, http://www.ethiopiaonlinevisa.com, http://www.evisaforethiopia.com or others”.
Repeat: the ONLY official e-visa website for Ethiopia www.evisa.gov.et.
