The ISS is a unique identifier your state assigns to your driver's license, separate from your driver's license number

ISS stands for "Issuance" and refers to a number printed on your driver's license that tracks when that specific card was issued. It is not your driver's license number itself — that is a different number on the same card. The ISS helps your state's motor vehicle department distinguish between multiple licenses you may have held over time, and it appears on every license you receive, whether it is your first one or a renewal.

The ISS is primarily a record-keeping tool for the state. When you renew your license, you get a new ISS number because you are receiving a new physical card. If you replace a lost or damaged license, that replacement also gets its own ISS number. This creates a paper trail that allows the Department of Motor Vehicles (DMV) to track the history of your licenses and catch fraud or duplicate licenses issued in error.

You will rarely need to reference your ISS in daily life. It does not appear on your insurance card, your vehicle registration, or documents you submit to employers or banks. It is there mainly for the state's internal use and for law enforcement if they need to verify the authenticity of your license or look up your complete licensing history.

Key Takeaways

  • ISS stands for Issuance and is a separate number from your driver's license number, printed on the front or back of your card depending on your state.
  • Each time you renew your license or replace a lost card, you receive a new ISS number because you are receiving a new physical license.
  • The ISS helps your state track which licenses belong to you and detect duplicate or fraudulent licenses issued under your name.
  • You do not need to provide your ISS to insurers, employers, or banks — it is used almost entirely by the DMV and law enforcement.

Where the ISS appears on your license and what it looks like

The location and format of the ISS varies by state. In most states, it appears as a small number printed on the front of the license, often near the bottom or in a corner. Some states print it on the back. The number is typically between two and six digits, though the exact length depends on your state's system.

On your license, you will see multiple numbers: your driver's license number (the main identifier), your date of birth, your license class, and your ISS. The ISS is usually labeled or positioned in a way that distinguishes it from the license number itself. If you are unsure which number is which, your state's DMV website lists the layout of the license and explains each field.

Why each renewal gives you a new ISS number

When you renew your driver's license, you receive a new physical card with a new ISS number. This happens even if your driver's license number stays the same. The reason is that the ISS is tied to the card itself, not to you as a person. A new card means a new issuance, and therefore a new ISS.

This system allows the DMV to maintain a complete record of every license card ever issued to you. If you renew every five or ten years (depending on your state), you will accumulate multiple ISS numbers over your lifetime. Law enforcement and the DMV can use this history to verify that a license is current and legitimate, and to spot patterns if someone tries to commit fraud using your identity.

How ISS helps prevent fraud and duplicate licenses

One of the main reasons states track ISS numbers is to catch errors and fraud. If a license is issued twice by mistake — for example, if a DMV employee processes your renewal twice — the duplicate will have a different ISS number. The state's system can flag this and cancel one of the licenses before it causes problems.

ISS also helps law enforcement verify that the license in front of them is genuine. A valid license will have an ISS number that matches the state's records for that card. If someone presents a forged or altered license, the ISS number may not match, or it may not exist in the system at all. This is one of several security features states use to make licenses harder to counterfeit.

The difference between ISS and your driver's license number

Your driver's license number is your primary identifier and usually stays the same throughout your life, even as you renew. It is the number you provide to insurance companies, employers, and law enforcement. Your ISS, by contrast, changes with each new card you receive.

Think of it this way: your driver's license number is like your name — it identifies you. Your ISS is like a serial number on a specific object — it identifies that particular card. When you renew and get a new card, you keep your name and your license number, but the card itself gets a new serial number (ISS).

When you might need to reference your ISS

In most everyday situations, you will not need to know or provide your ISS. Insurance companies ask for your driver's license number, not your ISS. Employers verify your identity using your license number. Banks and government agencies do the same.

The main time you might reference your ISS is if you are working with the DMV directly — for example, if you are disputing a record, requesting your complete licensing history, or investigating fraud. Law enforcement may also ask about it during a traffic stop if they are verifying the authenticity of your license, though this is uncommon. If you lose your license and need to report it, the DMV may ask for your ISS to help locate the correct record in their system.

How to find your ISS if you need it

Your ISS is printed directly on your driver's license. Look at the front and back of the card for a number labeled "ISS" or "Issuance." If you cannot locate it, your state's DMV website includes a diagram showing where each field appears on the license. You can also call your local DMV office and provide your driver's license number — they can look up your ISS in their system and read it to you over the phone.

If your license is lost or stolen, you can still find your ISS by logging into your state's DMV online portal if one is available. Many states allow you to view your license information and history online after you create an account. This is also useful if you need to verify your ISS for any reason without having the physical card in front of you.

Frequently Asked Questions

Does my ISS number change if I move to a different state?

Yes. When you transfer your license to a new state, you receive a new license card with a new ISS number. Your old state's ISS is part of your history in that state's system, but your new state assigns you a fresh ISS for your new license. Your driver's license number will also change because each state has its own numbering system.

Can I use my ISS number to look up my driving record?

No. Your driving record is tied to your driver's license number, not your ISS. If you need to order a copy of your driving record, you will provide your license number. The ISS is an internal tracking number and is not used for public record requests.

What happens to my old ISS numbers after I renew?

Your old ISS numbers remain in the DMV's database as part of your licensing history. They are not deleted or reused. This creates a complete record of every license card ever issued to you, which helps the state detect fraud and verify the authenticity of your current license.

Is the ISS the same as a security feature on my license?

No. The ISS is a record-keeping number, not a security feature like a hologram or watermark. However, the ISS works alongside other security features to help verify that a license is legitimate. A real license will have an ISS that matches the state's records; a forged license will not.
