Translating a Chinese birth certificate (出生医学证明)
The Medical Certificate of Birth is the primary relationship document in most Chinese immigration files. It is short, which makes people careless with it, and it is the parents' block rather than the child's that the reader is checking.
The 出生医学证明 — Medical Certificate of Birth — is issued by the hospital where the birth took place, on a national form administered by the health authority. It has been in national use since 1996, with several form revisions since; the field set below is stable across them, though the layout moves.
It is what USCIS, consulates and universities use to establish parentage. That is worth keeping in mind while translating it: the child's name and date of birth are the part everyone looks at, and the parents' identity block is the part that does the evidentiary work.
Field by field
| Chinese field | English | Notes |
|---|---|---|
| 出生医学证明编号 | Certificate number | One letter followed by digits, e.g. O123456789. The letter encodes the issuing batch — copy it |
| 新生儿姓名 | Name of newborn | Often blank or provisional on older certificates if the child was not yet named |
| 性别 | Sex | 男 male · 女 female |
| 出生时间 | Time of birth | Year, month, day, hour and minute. Translate the time too — it is printed and it is part of the record |
| 出生地点 | Place of birth | Province, city, district |
| 出生孕周 | Gestational age at birth | In weeks, e.g. 39 weeks |
| 健康状况 | Health status | Usually 良好 good |
| 体重 | Weight | In grams on most forms |
| 身长 | Length | In centimetres |
| 母亲姓名 | Mother's name | |
| 母亲年龄 | Mother's age | Age at the birth, not current age |
| 母亲国籍 | Mother's nationality | |
| 母亲民族 | Mother's ethnicity | Ethnicity, not nationality |
| 母亲有效身份证件类别 / 号码 | Type and number of the mother's valid identity document | Usually resident identity card |
| 父亲姓名 / 年龄 / 国籍 / 民族 / 证件类别 / 号码 | Father's name, age, nationality, ethnicity, identity document type and number | Same structure as the mother's block |
| 接生机构名称 | Name of the institution that attended the birth | |
| 接生人员签字 | Signature of the attending midwife or physician | Render as [Signature] — do not attempt to read a handwritten name |
| 签发单位 | Issuing institution | |
| 签发日期 | Date of issue | |
| 出生证明专用章 | Medical Certificate of Birth special seal | Round red seal, must be described |
Later revisions of the form also carry a barcode and a 打印序列号 (print serial number) distinct from the certificate number. If both are printed, both are transcribed.
The values that must be exact
- The certificate number, letter included. This is the value a verifying officer would use.
- Both parents' identity card numbers, 18 characters each, final character possibly an uppercase X.
- The date and time of birth, matching the passport and the hukou to the day.
- The mother's and father's names, matching every other document in the package — the same romanisation, in the same order, every time.
Things that go wrong
The parents' ID numbers are skipped as "not relevant". They are the most relevant thing on the page. The certificate proves parentage by tying two identified adults to one child, and the identification is the ID number.
民族 rendered as "nationality" next to 国籍 also rendered as "nationality". The document then contains two nationality fields with different values. 民族 is ethnicity; 国籍 is nationality.
出生时间 reduced to a date. The hour and minute are printed on the form. Dropping them makes the translation incomplete, and completeness is the actual legal requirement.
A handwritten attendant's name transcribed as a guess. If it is a signature, write [Signature]. Inventing a name that a verifier cannot match is worse than admitting it is a signature.
The seal skipped because "it's just a stamp". The seal names the issuing hospital. It is the source of the document's authority.
A replacement certificate translated as if it were the original. If the certificate is a 补发 (reissued) copy, the form says so, often with the original number referenced. Say so.
Second and third children
Certificates issued during the one-child policy era occasionally carry annotations relating to birth permits. If anything is written or stamped on the certificate, it goes in the translation. Deciding that an annotation is politically awkward and omitting it converts a complete translation into an incomplete one, and the omission is more conspicuous than the annotation.
Notarial route
For use abroad, the common route is not to translate the certificate loose but to obtain a 出生公证书 — a notarial certificate of birth — from a Chinese notary office, which packages the notary's attestation, a copy of the certificate and, if you request it, an English translation. That booklet is what gets the apostille.
Ask for the bilingual version. See apostilles on Chinese documents for what the apostille does and does not cover, and notarial certificates for how the booklet is structured.
FAQ
Is the 出生医学证明 the same as a birth certificate?
It is the Chinese equivalent and it is what receiving institutions mean when they ask for a Chinese birth certificate. Translating the title as "Medical Certificate of Birth" and noting that it is the birth certificate issued in China avoids a reader wondering whether they have the right document.
My certificate has no name for the child. Is that a problem?
Older certificates were sometimes issued before the child was named. Translate what is printed — blank stays blank. The hukou then carries the name, which is one reason both documents are usually submitted together.
What if the certificate is lost?
Reissue is handled by the health authority in the province of birth, and for many purposes a notarial certificate of birth based on the hukou and archival records is accepted instead. Which one the receiving institution wants is worth asking before spending on either.
Do I need to translate the back of the certificate?
If anything is printed or written on it, yes. Some revisions carry instructions or a change record on the reverse.
Does the translation need the hospital seal reproduced?
No — described. [Round red seal: XX Maternity Hospital, Medical Certificate of Birth Special Seal] satisfies completeness without copying an official seal into a document you produced.
Translating this document yourself?
CertTwin turns an uploaded document into a side-by-side draft you check yourself: tables kept intact, every digit frozen before translation and verified back into place by code, seals described rather than copied. US$1.00 per page.
