Does InterRent require an IDP in Guinea-Bissau?

InterRent's minimum rental age is typically 19-21 depending on country (19 in Spain, 21 in the UK and France), and drivers aged roughly 21-24 (24 and under in some markets) pay a young-driver surcharge that varies by location, for example around 8.50 EUR/day (max ~93 EUR) in Spain, 12.95 EUR/day (max ~181 EUR) in France, and about 35 GBP/day (max ~350 GBP) in the UK; some vehicle categories require drivers to be over 25.

A refundable security deposit is pre-authorised (held, not debited) on the main driver's credit card at pick-up; the card (Visa or Mastercard, sometimes Amex) must be in the main driver's name with an expiry date after the return date, and debit cards are not accepted because their rules do not fit InterRent's deposit policy.

Additional drivers must present their own valid driving licence at the counter and sign the rental agreement at pick-up; InterRent charges an extra-driver fee per day that varies by location, though it is frequently included in promotional/package rates. The main driver must have held a full, valid driving licence for a minimum of 12 months (one year) prior to picking up the vehicle.

Cross-border travel and one-way rentals are restricted and must be authorised in advance; cross-border fees and one-way drop-off charges apply and vary by route, with certain countries (typically higher-risk or non-EU destinations) excluded entirely under the rental conditions.

InterRent requires a full, valid driving licence held for at least 12 months; for licences not written in the Latin/Roman alphabet (or otherwise not understandable to the rental agent), an International Driving Permit (IDP) must be presented alongside the original national licence, as the IDP is a translation and never replaces the physical licence.

There is no functioning national motorway toll or vignette system; roads are funded publicly and you generally pay nothing to drive, though informal road barriers and checkpoints are common in the interior.

Parking in Bissau is largely informal and unmetered, with self-appointed attendants ('guardadores') expecting a small CFA-franc tip to watch the car; there are no painted paid-zone schemes or parking apps.

Enforcement is mostly by physical police/gendarme checkpoints rather than cameras; fines are usually negotiated and paid in cash on the spot, and the documented drink-drive limit is 0.15% BAC (15 mg/100 ml).

There is no reliable nationwide emergency line; in a serious crash do not move the vehicles if there are injuries, summon the Polícia de Ordem Pública locally and obtain a written police report (auto), which insurers and rental firms require.
