• In the U.S., there is no national requirement for non-citizens to obtain an IDP. Same goes for the rest of the world, although many countries, especially in Europe, are more receptive to the IDP and more familiar with it than we are.
• There are countries that recognize the IDP, but not your original driver license, and there are also car rental agencies abroad that would much prefer to see an IDP than some strange license from an estate.
• The IDP is about the same size as your passport book. It lists your name with photo identification, and it translates your driving privileges into 10 different languages, including French, German, Italian, Spanish, Russian, Chinese, Arabic, and the Scandinavian languages. It's recognized by more than 150 countries
• IDPs remain valid for one year from their date of issuance, and you must obtain them in your country of origin. If you establish residency abroad, the IDP will no longer suffice, and you'll need to take steps to obtain a local license.

• Full name
• Date of birth
• Address
• Valid driver license

The international driver permit translates your license into a standard format, and a host of languages, that allows foreign officials to better understand your driving privileges. It does not replace your license. The IDP, in and of itself, confers no driving privileges to you, although you must provide a valid license to obtain one. It's important to remember to carry both your driver license and your IDP with you whenever you make another foray on the roads of a foreign country.

There are countless organizations looking to make an extra buck off the IDP process. Remember that the State Department has authorized two motor clubs, AAA and NAC, to issue IDPs, and that you should pay no more than $15 for your permit.
If you fear that you've become the victim of IDP fraud, contact the Federal Trade Commission (FTC), the Better Business Bureau, or your local Attorney Generals office.
The State Department also recommends that you check with the embassies and consulates of the countries you plan to visit and inquire about specific licensing and insurance requirements, and local rules of the road.

This document can be used only as a driver license abroad.
