In most states, a certificate of incorporation and articles of incorporation are the same document under two different names. Delaware and New York call the founding filing a “certificate of incorporation.” Most other states call it “articles of incorporation.” The content is nearly identical, and the purpose is identical: it’s the document filed with the state that brings a corporation into legal existence. So the certificate vs articles of incorporation question almost always turns out to be a labeling difference, not a difference in what you actually file.
Why the Two Names Exist
The split traces back to how states wrote their business formation statutes. Most states adopted language from the Model Business Corporation Act, which uses “articles of incorporation” for the document filed with the Secretary of State. Delaware wrote its own corporate code and chose “certificate of incorporation” instead.1Justia. Delaware Code Title 8 Chapter 1 Subchapter I Section 104 – Certificate of Incorporation; Definition New York followed a similar path: a business corporation is formed by filing a certificate of incorporation with the Department of State.2Department of State.

The requirements the two labels cover are largely the same. Only the name on the form changes.
The Other Thing People Call a “Certificate”
A second layer of confusion comes from what the state sends back after you file. Once the filing is accepted, the state typically returns a stamped copy, a certified copy, or a filing receipt as proof the document went through. Some people call this confirmation a “certificate of incorporation” even in states where the filing document is called “articles of incorporation.”
That confirmation is proof of filing, not a separate governing document. In New York, for example, the Department of State issues a filing receipt showing the date of filing, the corporation’s name, and an extract of the information provided.2Department of State.

Keep whatever the state sends back somewhere safe. Banks, lenders, and business partners will ask to see it when you open accounts or sign contracts.
What the Filing Document Contains
Whether your state calls it articles or a certificate, expect to provide the same core information:
- Corporate name, including an identifier like “Inc.,” “Corp.,” or “Incorporated,” and distinguishable from other businesses already on file with the state.
- Registered agent: a person or company with a physical street address in the state of incorporation who agrees to accept legal documents on the corporation’s behalf. P.O. boxes and virtual offices generally don’t qualify.3Oregon Secretary of State. Articles of Incorporation Form Instructions
- Authorized shares: the maximum number of shares the corporation can issue, along with any classes of stock. The corporation can never issue more shares than the document authorizes without filing an amendment.
- Business purpose. Most states accept a broad statement covering “any lawful business activity.” A few require a more specific description, particularly for professional corporations like medical or legal practices.
- Incorporator information: the name and address of at least one incorporator, who signs and submits the document.
Delaware’s statute adds optional provisions that many incorporators use, such as limiting director liability for monetary damages or granting the board power to amend bylaws without a shareholder vote. That flexibility is one reason Delaware attracts so many incorporations.4Delaware Code.

Documents That Are Not the Same Thing
A few other documents get pulled into this question because their names sound similar. They aren’t interchangeable with articles or certificates of incorporation.
Articles of Organization
“Articles of Organization” is the formation document for a limited liability company, not a corporation. The names are close enough to cause real problems. If you file articles of organization when you meant to form a corporation, you’ve created an LLC instead, with different tax treatment, management, and ownership rules. Confirm which form you’re filing before you submit.
Certificate of Authority
A Certificate of Authority is not proof of incorporation. It authorizes a corporation already formed in one state to do business in a different state. It has nothing to do with creating the corporation in the first place.
Bylaws
Bylaws are the corporation’s internal operating rules. They cover how board meetings run, how directors are elected, and what officers do. Bylaws are not filed with the state. They’re adopted at the corporation’s first organizational meeting, usually by the initial directors. The articles or certificate of incorporation are the public filing that creates the corporation; bylaws are the private rules the corporation writes for itself.
Filing Cost and Timing
State filing fees for articles or certificates of incorporation range roughly from $35 to several hundred dollars, with most states charging between $50 and $150. Some states also assess fees based on the number of authorized shares or the par value of stock, which can raise the cost for corporations authorizing large amounts of stock.
Standard processing times vary. Some states process filings within a few business days; others take several weeks. Most states offer expedited processing for an additional fee, typically between $50 and $750 depending on the turnaround requested, with same-day or 24-hour service costing the most. Many Secretary of State offices now accept online filings, which tend to be processed faster than paper submissions.
The Short Version
If you’re incorporating in Delaware or New York, your founding document is called a certificate of incorporation. If you’re incorporating in most other states, the same document is called articles of incorporation. And if someone hands you a document labeled “certificate of incorporation” after filing in a state that uses “articles,” that’s almost certainly the state’s filing confirmation, not a second document you need to produce. One filing, one legal effect, two names.
