“Share certificate” and “stock certificate” commonly describe a certificate for shares in a corporation. An LLC membership certificate describes a different kind of interest. Choose the company’s actual legal form, then follow its records and applicable rules.
Choose by the company, not the heading
Company shares
Share / stock certificate

Describes a holder’s shares, including the number and class or series. ShareCert uses the heading “Share Certificate” for company shares, including U.S. corporation stock. The fields change with the company’s jurisdiction and type.

Membership certificate

Describes an LLC membership interest using its records and operating agreement. ShareCert’s LLC path uses whole units, with an optional percentage. It does not support percentage-only or fractional-unit certificates.

A stock certificate for one company is not a universal template for another. Formation law, governing documents, share classes, restrictions and signing arrangements can all affect the document.
For example, Delaware’s corporation law addresses both certificated and uncertificated shares in § 158. An attractive PDF alone does not establish that a company needs, or has properly issued, a certificate.
Why an LLC has a separate path
Do not describe an LLC interest as corporation stock simply because the designs look similar. Confirm that a certificate fits the LLC’s operating agreement and records, including how units, percentages, rights and transfers are described.
Delaware expressly provides for certificates of LLC interest unless the LLC agreement says otherwise. That is one jurisdiction’s rule, not a statement that every LLC must issue one. Read § 18-702(c).
What ShareCert does—and does not do
ShareCert formats the information you provide into a PDF. It does not issue shares, admit an LLC member, transfer ownership, update a register, verify a holding or arrange signatures.
If you are looking for the document used to form a company, this is not that document. Check the company’s formation records first. Then use the information checklist to prepare the certificate details.
