Certified vs Notarized Translation: Which One Do You Actually Need?
A certified translation is stamped by a translation provider to attest accuracy; a notarized translation adds a notary office's certificate. Visas and registrations usually take certified; Chinese civil documents used abroad usually need notarization, often plus an Apostille. Here's how to tell which you need.

If you're preparing documents for use abroad — or foreign documents for use in China — you'll eventually hit the same question: does the office want a certified translation or a notarized one? The two sound similar but represent two different kinds of endorsement. Pick the wrong one and you may redo the work, or worse, delay a visa or registration. Here's the difference, and how to tell which you need.
1. What a certified translation is
A certified translation is a translation issued by a qualified provider, carrying a certification of accuracy — a signed and sealed statement that the translation is complete and faithful to the original, plus the provider's official translation seal (and, where needed, business license and translator credentials). The party standing behind it is the translation company, and what it certifies is accuracy.
- Commonly accepted by: immigration and visa offices, universities, admissions bodies, and many courts and employers.
- Example: U.S. Citizenship and Immigration Services (USCIS) generally requires a certified English translation — a statement of accuracy — and does not require notarization for most filings.
2. What a notarized translation is
A notarized translation adds a second layer — an endorsement from a notary. One point is easy to miss:
- In many countries a notary public only attests to the translator's identity or signature, not to whether the translation itself is correct.
- In China, a notary office (公证处) issues a notarial certificate (公证书) that binds the original and the translation together and attests that the translation conforms to the original (most offices require a translation they approve). You can look up notary offices across China in our notary directory.
Typical uses: degrees, police clearance, birth, marriage and kinship documents used abroad — these usually need a notarial certificate, and often a further layer of authentication on top.
3. The difference in one line
| Certified translation | Notarized translation | |
|---|---|---|
| Who endorses it | Translation provider | Notary / notary office |
| What is endorsed | Accuracy of the translation | (China) translation conforms to the original; certificate issued |
| Typical use | Visas, registration, admissions | Chinese civil documents used abroad |
| Further authentication? | Usually none | Often Apostille / consular legalization |
4. One layer up: Apostille and legalization
After notarization, a document headed abroad may still need an Apostille or consular legalization. Since the Hague Apostille Convention took effect in China on 7 November 2023, an Apostille alone is usually enough between China and other member states — consular legalization is no longer required in most cases. See our companion piece, Apostille vs Three-Level Authentication.
5. So which do you actually need?
A rough guide (always defer to the receiving institution):
| Situation | Usually needs |
|---|---|
| Visa / immigration filing (e.g., USCIS) | Certified translation |
| Foreign birth certificate for China household registration | Certified translation (a few localities want notarization) |
| Chinese degree / police clearance used abroad | Notarized translation + Apostille depending on country |
| Court, property, inheritance documents | Usually notarized |
| University applications, transcripts | Usually certified |
6. Ask these three questions before you order
- Does the receiving office want a stamped/certified translation or a notarial certificate?
- Is an Apostille or consular legalization also required?
- Any specific requirement on target language or format (must it be bound to the original)?
Getting these answers first prevents most rework. Requirements vary by region — always follow the current rules of the destination and the receiving institution. If you're unsure, tell us the destination country, the purpose, and the receiving body, and we'll help you work out which route you need.
