Money & costs
The unit of currency is the naira. Bring only US dollars cash to Nigeria – travellers cheques are useless, although ATMs are becoming more widespread in cities. Avoid using a credit card in Nigeria because of fraud.
There are banks aplenty, but virtually none offer currency exchange – you’ll have to change on the street. Moneychangers are almost always Hausa, so it’s usually a safe bet to ask around at the town’s mosque. In our experience, the moneychangers are among the most honest in Africa. Western Union branches are everywhere if you need to get money wired to you.
