Filling in a car hire agreement in California can feel surprisingly high stakes. After a long flight, you are asked for a US address and phone number, even if you are only visiting for a few days. The good news is that most rental desks are used to international travellers. The less good news is that systems, staff training, and fraud checks vary by brand and location, so the “right” answer is really a set of acceptable options, plus a few common mistakes to avoid.
This guide explains what address and phone number tourists should put on a California car hire agreement, what typically gets accepted at the counter, and how to avoid the most common friction points.
Why rental desks ask for a US address and phone number
In California, car hire companies collect contact details for three practical reasons, identity and fraud checks, a way to reach you during the rental (breakdown, vehicle recalls, lost property), and a location to associate with the agreement for tax and compliance purposes. Many booking systems are designed around US residents, so they display required fields like “State” and “ZIP code” even when the driver is visiting from abroad.
That does not usually mean you must have a permanent US address or an American phone plan. It means you need to provide a contactable address for your stay, and a phone number the desk can record, plus any additional contact method they can use if they cannot reach you.
What US address should tourists use in California?
For most visitors, the safest and most widely accepted option is the address where you will be staying for the first night or two in California. That gives the rental company a real, verifiable location in the state, and it avoids the appearance of using a random address you cannot explain.
Option 1, your hotel address (recommended for most trips)
Using your hotel address is normal and widely accepted at major airports and city locations. Bring the booking confirmation on your phone, or have the details accessible offline. If the agent asks, simply say it is your accommodation during your stay.
Make sure the address is complete. Include hotel name, street number, street name, city, state (CA), and ZIP code. Many desk systems will not accept the entry without a ZIP code, even if the rest is correct.
Option 2, Airbnb, serviced apartment, or holiday rental address
Also acceptable, as long as it is a real address. If you are staying in multiple places, use the first accommodation where you will be reachable soonest. If your host uses a lockbox and there is no reception, that is still fine for the address field, but it makes the phone number field more important, since there is no front desk to relay messages.
Option 3, a friend or family member’s California address
If you are visiting someone locally, their home address is usually acceptable, especially if you will be there at some point during the rental. Only use this option if it is genuine and you can explain it. Do not use an address you found online, some desks will ask how you are connected to that address.
Option 4, your UK home address (only if the system allows)
Some agreements allow an international address and will simply record your UK address as-is. Others force “CA” and a five digit ZIP code. If the desk can accept an international address, using your home address can be sensible because it matches your driving licence and often matches your card billing profile.
However, if you are asked specifically for a US address in California, do not argue the point at the counter. Provide your accommodation address in California instead.
Common address pitfalls that cause counter delays
Missing ZIP code. A surprising number of check-in delays are simply because the address is incomplete. Look up the ZIP code for your hotel in advance, or copy the address from the hotel’s official confirmation.
Using the airport address. Some travellers put the airport terminal address, thinking it is “close enough”. That often looks suspicious and does not help the company contact you.
Using a random US address. Fraud screening can flag addresses that do not match the narrative of your trip. If asked, you should be able to say where you are staying and for how long.
Mismatch across documents. Your agreement address does not have to match your licence address, but mismatches combined with other issues (name variations, card discrepancies, missing middle name) can increase scrutiny. Keep your details consistent wherever possible.
What phone number should tourists use on a California car hire agreement?
Phone number requirements vary more than address requirements. Many desks will happily accept a UK mobile number with the international dialling code, but some locations prefer or require a US number, especially if their system is configured for domestic rentals or they rely on SMS verification.
Option 1, your UK mobile number (often accepted)
Give your UK mobile in international format, for example starting with +44. If the form will not accept the plus sign, ask the agent how they prefer it entered. The key is that the number must be reachable while you are in California. That means you should have roaming enabled or a way to receive calls.
If you use a UK number, keep your phone charged and unmuted at the counter and during the first day. If the rental company tries to call to confirm details, missing that call can slow things down.
Option 2, a travel eSIM or US SIM number (good for longer trips)
If you have a US travel eSIM number, that is typically the smoothest option because it looks like a standard domestic contact. This can also help if the desk sends texts about vehicle pickup, changes, or toll administration.
Not all travel eSIMs include a voice and SMS capable US number. If you have data-only service, do not claim it is your phone number for the agreement.
Option 3, your hotel front desk number (useful fallback)
If the desk insists on a US phone number and you do not have one, ask whether they can record your hotel front desk number as an additional contact. Many are willing to do this, especially when you can also provide your UK mobile and email. It is not perfect, but it is a legitimate, local number tied to your accommodation.
When using a hotel number, add your room number or booking name details to your own notes, and tell the hotel you may receive a call related to your rental. Some hotels will not disclose guest information by phone, but they may pass a message to your room.
Phone number pitfalls to avoid
Giving a number you cannot answer. If you provide a UK number but do not have roaming or you plan to keep the SIM off, you risk being uncontactable when the rental company needs you.
Using a messaging-only number. Some virtual numbers cannot receive standard verification texts or calls. If the desk relies on SMS, this can fail.
Letting the desk guess the format. International numbers can be entered incorrectly. Say the country code clearly and check what is printed on the agreement before you sign.
What happens if the counter requires a US phone number?
If a desk agent says their system requires a US number, stay calm and treat it as a process issue rather than a personal one. Ask if they can enter your UK mobile as the primary number and the hotel front desk as an alternate. If they cannot, and you have time, a US eSIM with a real number can solve it quickly for longer stays.
It also helps to pick up at major hubs where staff see more international rentals. If you are comparing California pickup points, Hola Car Rentals has location pages that help you understand the desk setup and airport process, such as Dollar car rental at San Francisco SFO and Avis car rental in San Diego. Even when requirements are similar, the on-the-ground experience can differ.
How to complete address fields correctly on US forms
California car hire agreements usually separate address into multiple boxes. Here is how to map UK style details into US fields without confusion.
Street address: Put building number and street name, plus apartment or unit if applicable.
City: Use the city where you are staying, for example Los Angeles, Anaheim, Santa Ana, or San Francisco.
State: Select CA.
ZIP code: Use the five digit ZIP for your accommodation. If you only have ZIP+4, the first five digits are usually enough.
Country: If there is a country field, choose United Kingdom for your home address, but for accommodation address you may choose United States if required. If the system only supports US addresses, stick with the California accommodation address.
Will the address affect insurance, deposits, or payment?
Usually, the address and phone number fields are administrative, not pricing drivers. Deposits and payment approval depend more on card type, driver age, licence validity, and whether the cardholder is present. However, inconsistent information can contribute to additional questions at the desk.
One practical tip, if the agreement is being set up under your name, try to ensure your name matches your driving licence and passport. Small differences, such as missing a middle name, are common but can cause delays when combined with other inconsistencies like an odd address choice.
Common pitfalls at the counter, and how to avoid them
Pitfall, arriving without accommodation details. If you cannot quickly provide a California address, the agent may have to pause the process. Save your first night address in your notes app, including ZIP code.
Pitfall, giving a UK number but having no signal. If your phone is not receiving calls, it can look like the number is wrong. If you plan to use a UK mobile, confirm you can receive calls in the US before you travel.
Pitfall, expecting the desk to accept any format. Some systems reject non-US formats. Ask the agent to read back what they entered, then check the printed agreement.
Pitfall, mixing driver and payer details. The agreement details should correspond to the main driver. If another person’s card is used, extra requirements often apply. Keep the contact details aligned with the person named on the agreement where possible.
If you are flying into Southern California, it can help to review your pickup location in advance. Hola Car Rentals provides airport and brand pages like car hire at Santa Ana SNA and Hertz car hire at Santa Ana SNA, which can reduce surprises on arrival.
A simple checklist for tourists before picking up in California
Have your first accommodation address ready with ZIP code, confirm your mobile will be contactable in the US, and carry booking and identification documents that match the driver details. If you suspect the desk may insist on a US number, consider arranging a US-capable number for the trip or plan to use your hotel front desk number as a backup contact.

Q: What if the desk says they need a US phone number?
A: Ask if they can add your hotel front desk number as an alternate contact, alongside your UK mobile and email. If they cannot, a US eSIM with a real number may be required.
Q: Should the address on the agreement match my driving licence address?
