What does a NAATI certified translation look like? Every stamp, seal and signature explained

Before you submit a translated document to the Department of Home Affairs, a university, or a state authority, it's worth knowing exactly what they're checking for. A NAATI certified translation isn't just a translated page. It's a translated page carrying a very specific set of marks that prove a credentialed translator stands behind it.

If even one of those marks is missing or wrong, your translation can be rejected. Here's a complete breakdown of what should appear on the page, why each element matters, and how you can verify it yourself.

The short answer

A NAATI certified translation must include:

• The translator's NAATI stamp (physical or digital)
• The translator's full name and practitioner ID (CPN)
• The language pair and direction (for example, French into English)
• The type of certification (such as Certified Translator)
• The date of the translation
• The translator's signature, or "Digitally Authenticated by NAATI" for digital stamps
• A QR code and the NAATI verification web address on digital stamps
• A faithful reproduction of any original seals and stamps from the source document

Every NAATI translation we deliver at EzyTranslate carries all of these. Here's what each one actually means.

1. The NAATI stamp

The stamp is the centrepiece. It's issued directly by NAATI, the National Accreditation Authority for Translators and Interpreters, and given only to translators who hold a current NAATI credential.

There are two valid formats.

A physical stamp is a rubber stamp issued by NAATI, applied in ink, accompanied by a handwritten signature and date.

A digital stamp is a NAATI-generated digital seal with a QR code, the text "Digitally Authenticated by NAATI", and a verification URL printed below the QR code.

Both formats are equally valid. Australian government agencies, courts, and universities accept either.

One thing to know about the stamp itself: the "valid to" date refers to when the translator needs to recertify, not to when the translation itself expires. A translation done by a NAATI-certified translator remains valid indefinitely, even after that translator's credentials lapse.

2. The translator's name and practitioner ID (CPN)

Every certified translator in Australia is issued a unique Certified Practitioner Number (CPN) by NAATI. It appears on the stamp alongside the translator's full legal name.

This is what allows anyone (you, an immigration case officer, a university admissions team) to verify the translator's credentials independently. You don't have to take anyone's word for it. You can look the number up.

3. The language pair and direction

The stamp specifies which languages the translator is certified to work between, and in which direction. For example:

• French into English means certified to translate from French to English
• English into French is a separate credential

A translator certified only into English cannot legally certify a translation going the other way. This matters: a stamp that doesn't match the direction of the translation is grounds for rejection.

4. The type of certification

NAATI issues several credential levels for translators. The most common ones you'll see on official translations are:

• Certified Translator, the standard credential for most official document translations
• Certified Advanced Translator, for complex or specialised content
• Recognised Practising Translator, granted in languages where NAATI doesn't currently run a test, but the translator has demonstrated work experience

For Australian visa and government submissions, all three are accepted, provided the credential is current.

5. The date

The stamp must show when the translation was completed for physical stamps, or when the digital stamp was generated for digital ones. This is required by DFAT for any translation that will be apostilled or used in international processes.

6. The signature, or "Digitally Authenticated by NAATI"

This is the translator's personal attestation that the translation is true and accurate.

On a physical stamp, this is a handwritten signature next to the stamp. On a digital stamp, it's replaced by the phrase "Digitally Authenticated by NAATI" embedded in the stamp itself.

Either form is legally equivalent.

7. The QR code and verification URL (digital stamps)

Digital stamps include a scannable QR code linking to NAATI's official verification page, plus a clearly legible web address printed underneath. Scanning the QR code (or typing the URL) brings up the translator's profile on NAATI's directory, confirming:

• Their name and practitioner number
• The credentials they currently hold
• Whether those credentials are active

This is the single fastest way to confirm a translation is genuine.

8. The original document's seals and stamps

A certified translation isn't just about the words. It's about the entire document. Any seal, stamp, watermark, or signature on the original must be reproduced and described in the translation.

NAATI's guidelines are explicit on this. Official Australian and foreign government seals should be preserved in their original format, with explanations or translations added in brackets where needed. For example:

[Round seal: République Française, Mairie de Paris]

Skipping these is one of the most common reasons translations get rejected. Translating only the names and dates on a birth certificate, for instance, will get it sent back. Birth certificates, marriage certificates and academic transcripts must be translated in full, every stamp included.

9. A copy of the source document

Best practice, and the standard at EzyTranslate, is for the translator to attach a copy of the source document to the translation, stamped or signed by the translator. This lets the receiving authority compare the translated page to the original side by side, and confirms which document the translator actually worked from.

How to verify a NAATI translator yourself

You don't need to take anyone's word for it. NAATI maintains a public verification tool:

1. Take the practitioner number (CPN) from the stamp.
2. Go to NAATI's Verify a Practitioner tool on naati.com.au.
3. Enter the number.

You'll see the translator's name, language pair, credential type, and whether their certification is currently valid. If a translator can't provide a CPN, or the number doesn't return a result, that's a red flag. A QR code is also delivered on the translation.

Red flags to watch for

A certified translation should never be:

• Missing a NAATI stamp or practitioner number
• Stamped only with a translation agency's logo (agencies aren't certified, translators are)
• Missing a date or signature
• Provided without any reproduction of the original document's seals
• Sold at a suspiciously low price with no verifiable CPN

Self-translations, translations by friends or family, and translations by non-NAATI translators are routinely rejected for Australian official submissions, even when they're linguistically accurate. The credential is what makes them legally acceptable.
