Quick Summary:

- Bring a passport or government photo ID matching the licence name.
- International visitors may need an International Driving Permit with licence.
- All additional drivers must be present to be added on-site.
Adding a second driver can make a California road trip far more comfortable, especially on longer routes between cities or when dealing with traffic around major airports. The key is that most rental desks treat an additional driver almost like a second renter. They usually need to meet the same identity and licence checks, and they must be added to the rental agreement before they drive.
This checklist focuses on documents for car hire pick-up in California, so you can add an extra driver at the counter without delays. Keep in mind that exact requirements vary by supplier, location, vehicle class, and your residency status. If in doubt, bring more identification than you think you will need.
Core documents an additional driver should bring
1) A valid driving licence
The additional driver must bring their physical driving licence. In most cases, a digital licence on a phone is not accepted. The licence should be current, legible, and suitable for the class of vehicle being rented. If the licence is damaged, has missing information, or is close to expiry, it can lead to delays or refusal to add the driver.
2) Photo identification that matches the licence
Expect the counter agent to verify identity, not just the licence. A passport is widely accepted for visitors. US residents often use a state-issued ID as well, but a passport can still be the most universally recognised option. The name on the ID should match the name on the driving licence. If there is a difference because of marriage or a legal name change, bring supporting documentation such as an official name change document, as mismatches can slow down processing.
3) International Driving Permit for some visitors
If the additional driver holds a non-US licence, they may be asked for an International Driving Permit (IDP) alongside the original licence. An IDP is not a licence on its own, it is a translation aid. Requirements can vary, but the safest approach is for international drivers to carry both documents to avoid a counter refusal.
What the rental desk usually checks, beyond the documents
Presence at the counter
In California, additional drivers typically must be present at the time of pick-up to be added to the agreement. This allows the desk to check the person’s documents and confirm they meet conditions such as minimum age. If your second driver arrives later, you may need to return to the branch together, which can be inconvenient if you have already left the airport area.
Age eligibility and licence history
Even with perfect documents, the additional driver must meet age rules and may need to have held their licence for a minimum period. These checks are policy based rather than document based, but they are a common reason an additional driver is not accepted. Bringing the correct documents helps you clear the identity side quickly, so any policy questions can be resolved faster.
Name matching and readability
Delays often happen when the agent cannot read key details on a licence, or when names differ between documents. If your additional driver uses two surnames, middle names, or different character sets, bring a passport and make sure the booking details reflect the licence as closely as possible.
Document checklist by traveller type
US residents driving in California
Bring a current US driving licence and a secondary photo ID if available. While a state driving licence is usually enough, having another form of ID can help if the system flags the record for any reason. The additional driver should also know their current address, as it may be requested during verification.
UK and EU visitors
Bring your photocard driving licence plus your passport. If your licence is not in English, or if you are unsure how the supplier treats foreign licences, carry an International Driving Permit as well. It is also helpful to have a copy of your travel itinerary accessible, as the desk sometimes confirms travel dates during check-in.
Other international visitors
Carry your passport, your home driving licence, and an International Driving Permit if applicable. If your licence uses a non-Latin alphabet, an IDP can reduce the chance of a delay. The additional driver should also be prepared to confirm their date of birth and home address as shown in official documents.
Do additional drivers need a credit card?
Usually, the primary renter provides the deposit and payment card, not each additional driver. However, policies differ by supplier and booking type. An agent may still ask for the additional driver’s details for verification, and some locations may require the additional driver to be listed and approved in the same way as the main driver. If your additional driver does have a credit card, it can be useful to have it available, but it is not typically the core requirement for being added.
Practical tips to avoid delays at California pick-up counters
Bring original documents, not photos
Photo scans and screenshots rarely satisfy counter checks. The additional driver should carry the original driving licence and original passport or ID.
Check expiration dates before you travel
A licence or passport that expires soon can cause problems. Even if it is technically valid on the day, some suppliers may not accept documents that expire during the rental period.
Arrive together and allow time
Airport pick-ups can be busy. When travelling through major hubs, like Los Angeles, allowing extra time helps if the desk needs to review an IDP or confirm a name match. If you are collecting near LAX, it can help to review local pick-up guidance on pages like car hire at Los Angeles Airport and car hire in California near LAX.
Consider where you are picking up and dropping off
Requirements are often consistent, but desk processes can vary slightly by location and brand. If you are collecting in Northern California, you may want to review the local branch information for car rental in San Jose. If your plans include a people carrier or larger vehicle, the same identity rules generally apply, and details can be found on van hire in San Jose.
Know what you are agreeing to
When you add a driver, they are legally bound by the rental terms. That is another reason they must be present with documents, so the agreement can be updated accurately. If your trip involves Southern California and you are comparing suppliers, you can also check pick-up expectations on pages such as Dollar car rental in San Diego.
Common issues that cause additional driver delays
The additional driver forgot their licence
This is the most common problem and usually cannot be solved at the counter. Plan for the additional driver to carry their licence on their person, not in checked luggage.
The licence is temporary or paper-only
Temporary documents may not be accepted. If your additional driver recently renewed their licence, bring the permanent card if possible, plus any official supporting document issued by the licensing authority.
IDP missing or incorrect
If an IDP is required, it must typically be issued in the driver’s home country before travel. Getting one after you arrive in California can be difficult. The IDP must accompany the original licence.
Name mismatches
Even small differences can trigger extra questions. Double-check that your booking and your additional driver’s documents align, especially where there are two surnames, middle names, or hyphenation.
