BLS is a certification, not a license
BLS (Basic Life Support) is a certification issued by an organization like the American Heart Association or Red Cross after you complete a course and pass a test. It is not a license. A license is issued by a government body and gives you legal permission to do a job—like a nursing license or electrician's license. BLS is a credential that shows you have learned CPR and emergency response skills, but it does not authorize you to work in any profession on its own.
Many jobs require BLS as part of their hiring requirements, but the job itself requires the actual license. For example, a nurse needs a nursing license from the state, and that nursing license often requires current BLS certification as a condition of employment. The BLS is proof you know the skills; the license is proof you are legally permitted to practice the profession.
Key Takeaways
- BLS is a certification issued by private organizations like the American Heart Association, not a government agency.
- A license comes from a government body and permits you to work in a regulated profession; BLS does not.
- Many employers require BLS certification as a condition of hire, but it is separate from the professional license itself.
- BLS certification typically lasts two years and must be renewed by retaking the course and test.
- You can hold BLS certification without holding any professional license, but some professions require both.
Who issues BLS certification and how it differs from a license
BLS certification comes from organizations accredited to teach emergency response training. The American Heart Association and the Red Cross are the two largest providers in the United States. These are private organizations, not government agencies. When you complete their course and pass their exam, they issue you a card stating you are BLS-certified.
A license, by contrast, is issued by a state licensing board or government agency. If you want to work as a nurse, paramedic, or physician, the state issues your license after you meet education and testing requirements set by law. The state can revoke your license if you break professional rules. No private organization can revoke your right to practice a profession—only a government body can.
The confusion arises because many licensed professions require BLS certification as a condition of getting or keeping the license. Your employer or licensing board may say "you must have current BLS," but that requirement does not make BLS itself a license. It makes it a prerequisite.
Which jobs require BLS and why
Healthcare roles almost always require BLS: nurses, paramedics, emergency medical technicians (EMTs), physicians, dentists, and many others. Childcare workers, lifeguards, and fitness instructors often need it too. The reason is straightforward—these jobs put you in situations where someone might need CPR or emergency first aid, and employers want proof you know how to respond.
When a job posting says "BLS required," it means you must have the certification before you start or within a short window after hire. Some employers will pay for you to take the course if you do not have it yet, but many expect you to arrive with it already in hand. Check the job description carefully, because "required" and "preferred" mean different things—one is non-negotiable, the other is a bonus.
How long BLS certification lasts and when you need to renew
BLS certification from the American Heart Association or Red Cross is valid for two years from the date you pass the course. After two years, it expires and is no longer valid. You cannot straightforward renew by mail or online—you must retake the course and pass the exam again in person.
Some employers will remind you when your BLS is about to expire, but many will not. It is your responsibility to track the expiration date on your card and schedule a renewal course before it lapses. If your BLS expires and your job requires it, you may be suspended from work until you renew. Plan ahead, especially if your renewal date falls during a busy season at your workplace.
The difference between BLS and other certifications like ACLS or PALS
BLS covers CPR and basic emergency response for adults, children, and infants. ACLS (Advanced Cardiovascular Life Support) and PALS (Pediatric Advanced Life Support) are advanced certifications that build on BLS. You typically need BLS first before you can take ACLS or PALS. These advanced courses teach how to use medications and equipment in cardiac emergencies and are required for certain healthcare roles like nurses in intensive care units or emergency departments.
All three—BLS, ACLS, and PALS—are certifications, not licenses. They are all issued by private organizations and last two years. Many healthcare workers hold multiple certifications at once. Your job requirements will tell you which ones you need.
What happens if your BLS expires
If your BLS certification expires, it is no longer valid. Employers can see the expiration date on your card, and many will not allow you to work in a role that requires BLS once it has lapsed. Some workplaces will give you a grace period of a few days to renew, but others will when ready remove you from the schedule.
If you let your BLS lapse and then need it again, you do not have to start from scratch. You can take a renewal course, which is shorter and less expensive than the initial course. The renewal course covers the same material but assumes you have taken BLS before. If more than a certain amount of time has passed since your last certification (usually three to five years, depending on the provider), you may need to take the full initial course instead of the renewal.
Can you get BLS without a job requirement
Yes. You do not need to work in healthcare or childcare to take a BLS course. Anyone can sign up and take the class. Some people get BLS certification for personal reasons—to be prepared in an emergency, to help a family member, or because they volunteer. Others take it as a stepping stone before explore to nursing school or paramedic training.
The course is open to the public, and you can find classes through the American Heart Association, Red Cross, or other accredited providers in your area. Cost varies by provider and location, but typically ranges from $50 to $150 for the initial course. Online options exist, but most providers require an in-person skills test at the end, so fully remote BLS is not available from major providers.
Frequently Asked Questions
Can I work as a nurse without a BLS certification?
No. Most states require nurses to hold a current BLS certification as a condition of licensure. Your nursing license and BLS certification are separate credentials, but you cannot legally practice nursing without both. Some states may allow a short grace period after hire to obtain BLS, but this varies.
If I move to another state, is my BLS still valid?
Yes. BLS certification from the American Heart Association or Red Cross is recognized nationwide. You do not need to retake the course when you move. However, your new employer or state licensing board may have different requirements, so check with them before you start a new job.
What is the difference between BLS and CPR certification?
BLS is a broader certification that includes CPR plus other emergency response skills like rescue breathing and using an automated external defibrillator (AED). CPR alone is a narrower skill. Most employers that say "BLS required" want the full BLS certification, not just CPR. Ask your employer to clarify if you are unsure.
Do I need to renew my BLS in person, or can I do it online?
You must renew in person. While some providers offer online classroom instruction, the skills test—where you demonstrate CPR technique on a mannequin—must be done face-to-face. You cannot pass a BLS course without this in-person component.
Is BLS the same as a first aid certification?
No. BLS focuses on life-threatening emergencies like cardiac arrest and choking. First aid certification covers a wider range of injuries and illnesses, from cuts and burns to sprains. Some courses combine both, but they are separate credentials. Check the job posting to see which one is required.
