The physical card and what's printed on it

An Illinois driver license is a wallet-sized plastic card, roughly the size of a credit card. The front displays your photograph in the upper left corner, your full name, date of birth, and address. Below that are your driver license number, the issue date, and the expiration date. On the right side you'll see your eye color, height, and sex. The card also shows any restrictions or endorsements that explore to your license — for example, corrective lenses required, or a commercial license designation.

The back of the card contains your signature, a barcode, and a magnetic stripe. These allow police officers and other officials to scan your information during traffic stops or age verification. The barcode and stripe hold the same data that appears on the front, so they're a quick way to confirm your identity without reading the card manually.

Illinois licenses are printed on a durable polycarbonate material that resists wear and fading. The card includes security features like a hologram and microprinting to prevent counterfeiting. Your license will remain valid until the expiration date printed on the front — typically four years from the issue date for a standard license.

Key Takeaways

  • Your Illinois driver license displays your photo, name, date of birth, address, and license number on the front, with your signature and barcode on the back.
  • The card includes your eye color, height, sex, and any restrictions or endorsements that affect how you can drive.
  • Illinois uses polycarbonate cards with security features like holograms to prevent forgery.
  • Your license remains valid until the expiration date printed on the front, which is typically four years from issue.
  • The barcode and magnetic stripe on the back allow officials to scan your information quickly during stops or verification checks.

License number format and what it means

Your Illinois driver license number is an 11-digit code that uniquely identifies you. The first digit is a check digit used to verify the number's validity. The next nine digits are derived from your name, date of birth, and sex using a formula that the Secretary of State's office applies to all licenses. The final digit is another check digit.

You cannot choose your license number — the Secretary of State assigns it based on your personal information. Two people with the same name and date of birth will receive different numbers because the formula accounts for sex as well. This number stays the same throughout your life unless you renew your license, at which point you receive a new number.

Restrictions and endorsements on your license

If your license includes restrictions, they appear as codes on the front. Common restrictions include "corrective lenses required" (code 2), "hearing aid required" (code 3), and "automatic transmission only" (code 4). These restrictions mean you must follow those conditions every time you drive, or your license is invalid for that trip.

Endorsements are different — they expand what you're allowed to drive. A commercial driver license (CDL) endorsement, for example, allows you to operate trucks or buses. Motorcycle endorsements allow you to ride motorcycles. These appear as letter codes on your license and are earned by passing additional tests beyond the standard written and driving exams.

How to read the dates on your license

Your Illinois license shows two key dates: the issue date and the expiration date. The issue date is when the Secretary of State printed and mailed your license. The expiration date is when your license stops being valid for driving. Standard licenses expire four years after issue. Licenses for drivers under 21 expire on their 21st birthday, and licenses for drivers 75 and older expire one year after issue.

You can continue to drive until midnight on the expiration date. After that, driving with an expired license is illegal, even if you've already submitted a renewal request. If you plan to renew, start the process at least two weeks before expiration to avoid a gap in validity.

Security features that prevent counterfeiting

Illinois driver licenses include several anti-counterfeiting measures. A hologram appears on the front of the card and changes appearance when you tilt it. Microprinting — tiny text visible only under magnification — is embedded in several places on the card. The polycarbonate material itself is difficult to replicate without specialized equipment.

The back of the card contains a barcode that encodes your personal information. When scanned, it must match the information printed on the front. If someone has altered or forged your license, the barcode will not match, and the scan will fail. This is why bars and retailers often scan licenses during age verification — the scan confirms the card is genuine and unaltered.

Differences between standard, commercial, and motorcycle licenses

A standard Illinois driver license allows you to operate passenger vehicles up to a certain weight. A commercial driver license (CDL) allows you to operate larger trucks and buses and requires additional testing and medical certification. The CDL designation appears on your license as an endorsement code.

A motorcycle endorsement allows you to legally ride motorcycles and appears as a separate code on your license. You can have both a standard license and a motorcycle endorsement on the same card. A CDL and motorcycle endorsement can also appear together, though this is less common. Each type requires passing its own written test and, in most cases, a separate driving skills test.

What happens when your license is suspended or revoked

If your license is suspended or revoked, you will receive a notice from the Secretary of State's office. A suspension is temporary — your license will be valid again after a certain period or after you meet specific conditions. A revocation is permanent, and you must reapply for a new license and pass all tests again to drive legally.

During a suspension or revocation, your physical license card remains in your possession, but it is no longer valid for driving. Driving with a suspended or revoked license is a criminal offense. If you're stopped by police, they can check the Secretary of State's database and will see that your license is not valid, even though the card itself looks normal.

Frequently Asked Questions

What does it mean if my license has a red bar or stripe?

A red bar on an Illinois license indicates that you are under 21 years old. This alerts retailers and bartenders that you are a minor, even if your appearance might suggest otherwise. The red bar disappears when you turn 21 and renew your license.

Can I use my Illinois driver license as a form of identification outside of driving?

Yes. Your Illinois driver license is a valid form of government-issued photo identification and is widely accepted for age verification, bank transactions, airport security, and other situations where ID is required. However, some organizations may ask for additional forms of identification depending on the context.

What should I do if my license is damaged or the information is hard to read?

Contact the Secretary of State's office to request a replacement card. You can do this online, by mail, or in person at a Driver Services facility. There is a fee for a replacement license, and you will receive a new card with a new expiration date.

Does my license number change if I renew my license?

Yes. When you renew your Illinois driver license, you receive a new license number. The old number is no longer valid. This is why it's important to update your license number with your employer, insurance company, and other organizations that have it on file.

What if I notice an error on my license after I receive it?

Contact the Secretary of State's office when ready with proof of the correct information — for example, a birth certificate if your date of birth is wrong, or a utility bill if your address is incorrect. The office will issue a corrected license at no charge if the error was their mistake.
