Where to find your class and credential number on your license

Your Massachusetts driver's license shows your class in the upper right corner of the front side, printed as a single letter (A, B, C, D, or M). The credential number — a unique identifier for your specific license — appears in the upper left corner, also on the front. Both are straightforward to spot once you know where to look, and you will need them if you are renewing by mail, updating your address, or checking your driving record online.

If you cannot find these numbers on your physical card, you can also look them up through the Massachusetts Registry of Motor Vehicles (RMV) online portal or by calling the RMV at 857-368-8000. Have your Social Security number and date of birth ready when you call.

Key Takeaways

  • Your license class (A, B, C, D, or M) is printed in the upper right corner of the front of your card.
  • Your credential number is a unique identifier printed in the upper left corner of the front of your card.
  • You can look up both numbers through the RMV online portal or by phone if your physical license is lost or damaged.
  • Your class determines what vehicles you are legally allowed to drive in Massachusetts.

What each Massachusetts license class means

Class A allows you to drive any vehicle, including tractor-trailers and buses. You must be at least 18 years old and pass additional testing beyond the standard road test.

Class B covers most commercial trucks and vehicles over 26,000 pounds gross vehicle weight rating (GVWR). Like Class A, it requires you to be 18 or older and pass commercial driving tests.

Class C is the standard passenger vehicle license. It covers cars, small trucks, and vans up to 26,000 pounds GVWR. Most new drivers in Massachusetts receive a Class C license after passing their road test.

Class D is a restricted license for drivers who do not meet the vision or medical standards for a full Class C license. It may come with conditions, such as wearing corrective lenses or driving only during daylight hours.

Class M is a motorcycle license. You must pass a separate motorcycle road test and meet additional safety requirements to receive this class.

Why you need your credential number

Your credential number is a permanent identifier tied to your driving record in Massachusetts. The RMV uses it to track your violations, accidents, points, and license status. When you renew your license by mail, you will need to provide this number so the RMV can match your process to your existing record.

You will also need your credential number if you are checking your driving record online, requesting an official copy of your record, or disputing a violation or accident report. Insurance companies sometimes ask for it when you are getting a quote, and employers may request it if the job involves driving.

How to look up your information online

The Massachusetts RMV offers an online portal where you can view your driving record and license information without calling. Go to mass.gov/rmv and select "Check Your Driving Record" or "License Information." You will need to log in with your Social Security number, date of birth, and license number (which is the same as your credential number).

The online portal also lets you renew your license, update your address, and request copies of your record. If you do not have internet access or prefer to speak with someone, call the RMV at 857-368-8000. Wait times are typically shorter early in the morning on weekdays.

What to do if your license is lost or damaged

If you cannot read your credential number or class because your license is worn, faded, or damaged, you can request a replacement card from the RMV. You can do this online through mass.gov/rmv, by mail, or in person at an RMV branch. The replacement fee is typically $25 to $30, though this varies depending on how long your current license is valid.

When you request a replacement, the RMV will issue a new card with the same credential number and class. Your driving record and all associated information stay the same — only the physical card is replaced. You should receive your new card within two to three weeks if you explore by mail.

Understanding your license expiration and renewal

Massachusetts driver's licenses are valid for five years from the date of issue. Your expiration date is printed on the front of your card, below your photograph. When your license is about to expire, the RMV will send you a renewal notice in the mail about 60 days before the expiration date.

You can renew by mail, online, or in person at an RMV branch. If you renew by mail or online, you will need your credential number and current license number. Your new license will have the same class unless you have requested a change or the RMV has determined you no longer meet the medical or vision standards for your current class.

Frequently Asked Questions

Is my credential number the same as my license number?

Yes. Your credential number and license number are the same thing. Both refer to the unique identifier printed in the upper left corner of your Massachusetts driver's license. You will see this number used interchangeably on RMV documents and online portals.

Can I change my license class without taking another road test?

It depends on the change. If you want to add a motorcycle endorsement (Class M), you must pass a separate motorcycle road test. If you want to downgrade from Class A or B to Class C, you typically do not need a new test. Contact the RMV to confirm what is required for your specific situation.

What happens if I drive a vehicle that is not allowed by my license class?

Driving a vehicle outside your license class is a violation in Massachusetts. You could face fines, points on your record, and license suspension. For example, driving a commercial truck with only a Class C license is illegal, even if you are otherwise a safe driver.

How do I know if my Class D license has restrictions?

Your restrictions are printed on the back of your Class D license card. Common restrictions include "corrective lenses required" or "daylight driving only." You must follow all restrictions listed on your card. If you believe a restriction is incorrect, contact the RMV to request a review.

Can I look up someone else's credential number and driving record?

No. The RMV only releases driving record information to the license holder, their attorney, or an insurance company with a signed authorization. You cannot look up another person's information without their permission, even if you are a family member.
