"License" vs "certificate": understanding the distinctions

What is similar?

Both "license" and "certificate" are official documents issued by an authority. They serve as proof that an individual or entity has met certain standards or qualifications. Both may be required to engage in specific activities or professions, validating compliance with legal or professional requirements.

What is different?

"License" is a document that grants permission to perform a particular activity, often legally required and sometimes needing periodic renewal (e.g., driver's license, business license). It typically confers the right to do something. "Certificate" is a document that attests to a fact or completion of a course or achievement (e.g., birth certificate, graduation certificate). It usually serves as evidence of a qualification or accomplishment but doesn't necessarily grant permission to perform activities.
