Does Alamo require an IDP in Guinea-Bissau?

Alamo's standard minimum rental age in the US is 21 (18 in Michigan and New York where state law requires it); renters aged 21-24 pay a "young/youthful driver" surcharge that averages about $25 per day but varies by location (for example roughly $13/day in Michigan and $20/day in New York), and under-25 renters may be restricted to certain car classes.

A major credit card in the primary renter's name is required at most locations; debit/check cards bearing a Visa, Mastercard or Discover logo are accepted at airport locations only with a ticketed return travel itinerary (Discover not accepted in Canada), and the name/address on the card and license must match, with a hold placed at pickup that reduces available funds.

Additional authorized drivers typically cost about $15 per day each (around $5/day in New York), and every additional driver must also meet the minimum-age and license requirements; some promotions or contracted/corporate rates waive the fee. Alamo requires each driver to hold a valid, unexpired driver's license; the license must have been issued before the rental and held for the qualifying period, with locations commonly expecting it to have been held for at least 1 year.

Vehicles rented in the US may typically be driven throughout the US and Canada but cannot be taken into Mexico; vehicles rented in Canada may be driven in Canada and the US. Cross-border and one-way rentals must be disclosed and authorized at the counter, and one-way availability and drop fees vary by location.

Alamo states an International Driving Permit cannot be used on its own and the home-country license must always be presented; an IDP is recommended (not required) when the license uses Roman/English letters, but is required when the license is in a non-Roman alphabet (e.g. Russian, Japanese, Arabic), with a typed professional translation as a substitute if no IDP is available.

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.
