How to Call France from the USA in 2026: +33 Dialling Guide

What should you dial for a French number?

Keep the digits after the domestic leading zero. Do not dial both + and 011, and do not add +33 twice to a number already written internationally.

The patterns below are illustrations, not complete phone numbers. Each X stands for a digit in the recipient's actual number.

Do landlines and mobiles use different country codes?

Both ordinary mainland French landlines and mobiles use +33. Arcep lists ten-digit domestic numbers, with 01–05 and 09 used for multipurpose numbers and mobile ranges beginning 06 and parts of 07. The prefix can help identify the category; it does not tell you the caller's current location.

Do not assume an 01–05 number proves where an office is based. Arcep removed geographic location restrictions for these fixed numbers within the relevant French territory in January 2023. Use the business's own contact page to confirm which office or department answers.

How to place a US-to-France browser call

Prepare the contact details before opening the dialer. For a reservation or appointment, keep your booking reference and the name of the person or department you need nearby.

1. 1. Get the official number. Copy it from the recipient's website, confirmation email or established contact record. Choose a normal international contact number where one is offered.
2. 2. Convert it to +33. Remove the first domestic 0 from a standard mainland number. If +33 is already present, remove only an optional (0) shown after the country code.
3. 3. Check the price. Look up the destination and number type on the rates page. Review your available credits; a country code alone does not establish a rate or guarantee that every prefix is supported.
4. 4. Prepare the audio. Sign in, allow microphone access and select the intended microphone and speaker. A headset helps keep an office call private and reduces echo.
5. 5. Call and enter any extension afterwards. Dial the main number first. Keep an extension separate rather than appending it to the international number, then use keypad tones when the business prompts you.

What about French overseas, short and premium numbers?

This guide's +33 conversion covers ordinary mainland French numbers. Some French overseas territories use different country codes. Confirm the exact destination's international number rather than changing an overseas contact to +33 because its address says France.

Arcep also lists 08 service numbers and shorter assistance or information numbers. Their domestic availability and charges do not prove that a US carrier or browser service can reach them. If a business publishes only a short code or special number, ask for its regular international contact line.

When should you call a French business from the USA?

Check the office's local time and its published opening hours for the actual date of your call. The USA spans several time zones, so a morning call from New York and a morning call from California reach France at different times.

Use a calendar with both your US city and the French city selected. Daylight-saving changes can shift the gap for part of the year. For a hotel arrival or appointment, specify the date and French local time in your notes to avoid discussing different days.

What should you check if the call does not connect?

First check for +33 0, a duplicated country code, a missing digit or an extension pasted into the main number. Then check whether the published contact is a short, premium or domestic-only service number. A correctly formatted number may still be unavailable through your chosen provider.

If you connect but cannot hear the other person, inspect the selected speaker and microphone permissions. If the number fails repeatedly, use the recipient's official email or contact form to request an ordinary international number. Avoid making repeated paid attempts without checking the cause.
