YELLOW FEVER VACCINATION
If you’re traveling to Nigeria, you’ll need to get a Yellow Fever vaccination at least 10 days before your trip. Be sure to bring your Yellow Card, since you might need to show it when you arrive.
TIPPING / GRATUITIES

Tipping is appreciated but not always expected. In restaurants, a 5–10% gratuity is customary for good service. Some upscale establishments may include a service charge in the bill - check before adding a tip. Tipping service staff such as hotel porters, taxi drivers, and attendants is welcomed, usually in small denominations of local currency (e.g. ₦1000).

ELECTRICITY

Nigeria operates on a 230-volt supply voltage and 50Hz. The standard plug types are types D and G (UK-style three-pin). Visitors from countries using different voltage or plug types should bring a suitable adapter and voltage converter if necessary. Many hotels provide adapters upon request, and backup power systems (e.g. generators or inverters) are common due to intermittent outages.

WATER

Tap water in Lagos is not recommended for drinking. It is advisable to drink bottled or filtered water, which is widely available in hotels, restaurants, and stores. Most hotels provide complimentary bottled water for guests. Use bottled water for brushing teeth as an extra precaution.

SAFETY /SECURITY

Delegates are advised to take standard safety precautions. Avoid walking alone at night, especially in quiet or poorly lit areas. Use reputable ride-hailing services such as Uber or Bolt for transportation after dark. If unsure about the safety of a particular area, consult your hotel concierge or local host. Avoid drawing attention by displaying valuables such as cameras, expensive jewellery, or designer accessories when out and about. Use your hotel room safe or a secure deposit box to store passports and valuables.

SMOKING

Smoking is prohibited by law in enclosed public spaces in Nigeria, including airports, shopping malls, and restaurants. Some public venues may provide designated smoking areas - please observe local signage.

VALUE ADDED TAX

VAT is included in the price of most goods and services in Nigeria. There is no formal VAT refund scheme for tourists departing the country, however please retain your receipts for record-keeping or evidence of purchase when leaving the country.

MOBILE PHONES & SIM CARDS
A National Identification Number (NIN) is required to purchase a Nigerian SIM card. As NINs are issued only to citizens and residents, most foreign visitors will not be eligible.

Local SIM cards from providers such as MTN, Airtel, or Glo are widely available at airports, malls, and convenience shops. Ensure your phone is unlocked for compatibility. Airtime and mobile data bundles can be purchased easily via scratch cards or mobile apps.

WI-FI & INTERNAT ACCESS
Wi-Fi at the airport and in public places is often unreliable. To stay connected, consider using an eSIM service or set up roaming with your home provider before you travel.
VISAS

Delegates requiring a Nigerian visa should apply as early as possible, as processing times may vary. An invitation letter from the conference organizers will assist your application. Visa-on-arrival may be available for citizens of certain countries—please check with the Nigerian Immigration Service or the nearest Nigerian Embassy/Consulate for up-to-date requirements.
