A certified copy and a notarized copy are not interchangeable, and the difference between a certified copy vs. a notarized copy decides whether an agency accepts your paperwork or sends you back to start over. A certified copy is produced and sealed by the government office or court that holds the original record. A notarized copy is a photocopy that a notary public has compared against your original and stamped as a true reproduction. Federal agencies that handle vital records almost always demand the first and reject the second.
What a Certified Copy Is
A certified copy comes directly from the office that stores the original document. For a birth certificate, that is the state or county vital records office. For a court order, it is the clerk of the court that issued it. The custodian of records reproduces the original, attaches a written statement that the copy is a true and complete reproduction, and applies an official seal or stamp. That seal gives the document the same legal weight as the original for most purposes.
The seal is the whole point. It tells every downstream agency that the copy was produced by someone with legal authority over the original file, with no intermediary in between. Under Rule 902(4) of the Federal Rules of Evidence, certified copies of public records are self-authenticating, meaning a court accepts them without additional testimony about their genuineness.1Legal Information Institute. Federal Rules of Evidence Rule 902 – Evidence That Is Self-Authenticating
What a Notarized Copy Is
A notarized copy involves a different chain of trust. You bring your original document and a photocopy to a notary public. The notary compares the two, confirms they match, and completes a certificate stating the copy is a true reproduction of the document you presented. The notary signs the certificate and applies their official stamp.
Here is the critical difference: the notary is not vouching for the authenticity of your original. They are only confirming that the photocopy matches whatever you showed them. If the original is itself a forgery, the notarized copy carries that same defect. That is why agencies that need absolute confidence in a document’s origins require certified copies from the issuing office.
Not every state even authorizes notaries to certify copies. Several states prohibit the act entirely, and others restrict it to documents that are not available as certified copies from a government source. When a certified copy exists from an official custodian, that version almost always takes priority.
When You Need a Certified Copy
The general rule is simple. If the document was originally created or filed by a government agency or court, you need a certified copy from that same office. Ordinary photocopies and notarized copies will be rejected.
Passports
The U.S. Department of State requires a birth certificate issued by the city, county, or state of birth that lists both the applicant’s and parent’s full names, bears the registrar’s signature, and carries the seal or stamp of the issuing authority.2U.S. Department of State.

Social Security Benefits
The Social Security Administration requires original documents or copies certified by the issuing agency when you apply for retirement benefits or a Social Security number. The agency’s instructions are explicit: “We cannot accept photocopies or notarized copies.”3Social Security Administration. Retirement Planner: What Documents Do You Need to Apply for Retirement Benefits? That covers birth certificates, citizenship proof, and other identity documents.
Employment Verification (Form I-9)
If you use a birth certificate as your List C document on Form I-9 to prove employment authorization, it must be an original or a certified copy bearing an official seal.4U.S. Citizenship and Immigration Services. Form I-9 Acceptable Documents A notarized copy is not acceptable. Other List C documents like a Social Security card must also be originals.
Court Filings
Federal courts treat certified copies of public records as self-authenticating under Rule 902(4). A notarized photocopy of a court order or government filing would need additional foundation testimony to be admitted, and many courts will not accept it when a certified copy is available.
When a Notarized Copy Works
Notarized copies fill the gap for private documents that were never filed with a government office. No official custodian holds the original, so there is no agency that can issue a certified copy. The notary steps in as the next-best verification.
Common examples include university diplomas, professional licenses issued by private organizations, employment contracts, corporate bylaws, and personal financial records such as bank statements. When a company asks for a notarized copy of your degree during a hiring process, they want assurance that you showed a real diploma to an impartial witness rather than submitting a doctored image.
International school admissions frequently require notarized copies of academic transcripts. Private business deals may call for notarized copies of organizational documents. Landlords sometimes accept notarized copies of pay stubs or tax returns as part of a rental application. In each case, the notary’s stamp adds a layer of trust that a plain photocopy lacks, without pulling in a government office.
The key limit: a notarized copy is generally not acceptable as a substitute for a certified copy when the certified version exists. If a government agency holds your original record, go to that agency. Save the notary for documents only you possess.
Documents You Cannot Freely Copy
Some documents carry legal restrictions on reproduction regardless of which type of copy you want. The most important category is immigration and naturalization records.
Under federal law, making unauthorized reproductions of a certificate of naturalization, certificate of citizenship, or declaration of intention to become a citizen can carry criminal penalties of up to 10 years in prison for a first offense. The penalty increases to 20 years if connected to drug trafficking and 25 years if connected to international terrorism.5Office of the Law Revision Counsel. 18 U.S. Code 1426 – Reproduction of Naturalization or Citizenship Papers A notary should refuse to make or certify copies of these documents, and you should not photocopy them on your own without authorization.
If you need a verified copy of a naturalization certificate for use outside the U.S. government, USCIS requires an in-person appointment at a local office. You must bring the original certificate, a photocopy, and photo identification. USCIS does not process these requests by mail or electronically.6U.S. Citizenship and Immigration Services. How Do I Obtain an Authenticated Copy of a Certificate of Naturalization For routine U.S. government business like a passport application, you submit the original certificate itself rather than any copy.
Many states also restrict notaries from certifying copies of vital records such as birth, death, and marriage certificates, or court-issued documents. The reasoning is consistent. When an official custodian can provide a certified copy, there is no reason for a notary to create a competing version of uncertain provenance.
Using Documents Internationally
When you need to use a U.S. document in another country, neither type of copy may be enough on its own. Most countries require an additional layer of authentication called an apostille.
An apostille is a certificate issued under the 1961 Hague Convention that verifies the signature and seal on a public document so foreign governments will accept it. There are 129 countries that participate in the Hague Apostille Convention.7HCCH. Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents For documents issued by the U.S. federal government, the apostille comes from the U.S. Department of State. For state-issued documents like birth certificates, the apostille comes from the secretary of state (or equivalent office) of the state that issued the document.8U.S. Department of State. Preparing a Document for an Apostille Certificate
If the destination country is not part of the Hague Convention, you need a different process called authentication, which involves both the state and the U.S. Department of State. The federal authentication fee is $20 per document.9U.S. Department of State. Requesting Authentication Services Processing times vary, so build in extra weeks when planning international applications.
The practical order for international use is usually to obtain the certified copy from the issuing government office first, then get the apostille or authentication from the appropriate authority. A notarized copy of a private document going overseas may also need an apostille on the notary’s certificate, depending on the receiving country’s requirements.
What Each Type Costs
Certified copy fees are set by the government office that issues them. For vital records like birth and death certificates, fees vary by state and county but generally fall in the $10 to $35 range for a single copy. Some offices charge extra for expedited processing. Court-certified copies of legal filings often carry per-page charges on top of a base certification fee. You can usually find the exact cost on the issuing office’s website before you apply.
Notary fees for copy certification are regulated by state law and are considerably cheaper. Most states cap fees for notarial acts between $2 and $15, though the exact ceiling depends on your state. Some states charge per page while others charge per notarial act. Mobile notaries who travel to your location frequently add a travel fee that is not subject to the same statutory caps.
For international use, add the apostille or authentication fee. The U.S. Department of State charges $20 per document for federal authentication. State-level apostille fees vary but are usually modest. The real cost of international document authentication is often the processing time rather than the dollars.
Quick Decision Guide
If the document was created or filed by a government agency or court, get a certified copy from that office. If the document is private and only you hold the original, a notarized copy is the right move. If the document is going overseas, plan for an apostille on top of whichever copy you need. And if the document is a naturalization or citizenship certificate, do not copy it yourself. Go through USCIS for an authorized reproduction.
