Before buying the IDL or ID card from any company you have to know:

1. The IDL is a NON-Government document.
2. The IDL can't substitute a state-issued driver's license and a photo ID card.
3. The IDL can't verify your identity.
4. The IDL doesn't give you the permission to drive legally in the U.S. and any other country without a state-issued driver's license, a state-issued identification card, valid immigration documents, or a passport. ( Note: IDL is not recognized in all U.S. States )
5. The IDL can't be used in the country where you received your state-issued driver's license.
6. If you are a U.S. resident, an IDL is of no use within the U.S.
7. All rental car companies have their own corporation rules. If you plan to rent a car in some country, you have to call the rental company and observe the company's rules and regulations before you buy the IDL.
