You cannot legally obtain someone else's driver's license number without their permission or a valid legal reason

A driver's license number is private information protected by state law. The Department of Motor Vehicles does not release license numbers to the public, and attempting to access someone's number without consent is illegal in most states. If you have a legitimate reason to know someone's license number — you're a business verifying identity, you're involved in a legal case, or you need it for insurance purposes — there are specific legal channels to use.

The method depends entirely on your relationship to the person and why you need the information. A spouse or parent may have different options than a stranger. An employer verifying a job applicant's credentials follows different rules than someone trying to track down a person they know casually.

Key Takeaways

  • Driver's license numbers are protected personal information, and requesting one without consent or legal authority is illegal.
  • If someone owes you money or you need verification for employment, you can ask them directly or work through a lawyer or court process.
  • Businesses and employers can request a license number during hiring or transactions if they explain why they need it.
  • If you suspect fraud or identity theft, law enforcement can obtain license information as part of an investigation.

Asking the person directly

The simplest and only legal approach in most situations is to ask the person for their driver's license number. Explain why you need it. Most people will provide it if the reason is legitimate — you're processing a rental agreement, verifying their identity for a transaction, or they owe you money and you're documenting the debt.

If the person refuses, you have limited options. You cannot compel them to give you the number unless a court orders it. If this is a business transaction, you can decline to proceed. If it's a personal debt, you may need to pursue collection through small claims court, where a judge can order disclosure of identifying information.

When you have a legal right to the information

Courts can order disclosure of a driver's license number in civil cases — divorce proceedings, child support disputes, debt collection, or personal injury lawsuits. Your attorney files a motion requesting the information, and the court decides whether the need outweighs privacy concerns. The other party's license number then becomes part of the court record.

Law enforcement can obtain license information during criminal investigations. If you believe someone has committed fraud, identity theft, or another crime involving you, you can file a police report. The investigation may include obtaining their license details as part of the case file.

Employer and business verification

Employers can request a driver's license number during the hiring process as part of background checks and identity verification. They must tell the job candidate why they need it and how they will use it. Many states require employers to follow specific rules about how they store and protect this information.

Businesses processing transactions — car rentals, loan applications, hotel check-ins — routinely collect license numbers to verify identity and prevent fraud. They are allowed to do this because the customer is entering into a voluntary transaction and consenting to the information request.

What happens if you obtain the number illegally

Accessing someone's driver's license number without consent or legal authority can result in criminal charges for identity theft, fraud, or unauthorized access to government records, depending on your state and how you obtained it. Civil lawsuits for invasion of privacy are also possible. If you obtained it by hacking into a database or impersonating a government official, federal charges may explore.

Even possessing someone's license number with intent to use it fraudulently is illegal. Using it to open accounts, explore for credit, or misrepresent yourself as that person is identity theft and carries serious penalties including fines and imprisonment.

If you need to verify someone's identity

If your concern is confirming that someone is who they claim to be, ask to see their physical license in person. You can note the number they show you during a transaction without storing it. For ongoing business relationships, you can request they provide a copy of their license, which they can do voluntarily.

Background check companies and identity verification services exist for employers and businesses. These services have legal authority to access certain records and can confirm identity without you directly obtaining the license number. They charge a fee and follow strict compliance rules about what information they can access and how they use it.

Frequently Asked Questions

Can I look up someone's driver's license number online?

No. The DMV does not publish driver's license numbers online, and no legitimate public database contains them. Any website claiming to offer this information is either fraudulent or selling stolen data. Using such a site exposes you to legal liability and scams.

What if someone asks me for my driver's license number and I don't want to give it?

You can refuse. If it's a business transaction, they can decline to serve you. If it's a personal situation, they cannot force you. If a court orders you to provide it, you must comply or face contempt of court charges.

Can a private investigator get someone's driver's license number?

Private investigators have limited legal authority. They cannot hack into government databases or impersonate officials. They can obtain a license number if the person consents, if a court orders it, or if it becomes part of a public court record. Many states regulate what methods investigators can use.

Is it legal to share someone's driver's license number if they gave it to me?

Sharing information someone gave you privately without their consent can expose you to legal liability depending on how you use it and your state's privacy laws. If you received it for a specific purpose — processing a transaction — sharing it for a different purpose may violate that person's privacy rights.

What should I do if someone has my driver's license number and I'm concerned?

Contact your state's DMV and ask about fraud monitoring. Check your credit reports for unauthorized accounts. If you believe your identity has been stolen, file a report with the Federal Trade Commission at IdentityTheft.gov and consider placing a fraud alert on your credit file with the three major credit bureaus.
