以下内容均转录自该机关自己发布的官方资料，并按原文表述呈现。若某项内容无法在官方页面上得到确认，会标有"未经核实"标记——但没有该标记，并不代表该事实已经过核实；来源自身存疑之处也会照录于本页所附的说明中。发送文件或款项前，请务必向该机关确认费用、地址与截止日期。

- **附加证明书手册:** District of Columbia, 美国
- **核实日期：** August 9, 2026

## 由谁签发附加证明书

Office of the Secretary of the District of Columbia — Office of Notary Commissions and Authentications (ONCA)

## 该机关接受哪些文件

- **来源原文:** Only documents notarized by a DC notary public OR certified/signed by a DC government agency Department Head (e.g., DC birth certificates, DC Public School diplomas, MPD FL-20 police clearances); court documents only if issued by DC Superior Court (marriage certificates, divorce decrees, etc.); most federal documents (FBI results, passports) not accepted — US Dept. of State handles those

## 可能需要先行办理的认证

申请附加证明书前，无需额外的认证步骤。

## 申请表

PDF申请表。 获取方式: https://os.dc.gov/sites/default/files/dc/sites/os/page_content/attachments/Mail-In%20Request%20for%20Authentications_Updated.pdf

## 在线申请

没有在线申请渠道——该机关仅接受纸质申请。 No true portal — ONCA "Mail In Services Request Notification Form" (Microsoft Forms) is a notification step only; nap.os.dc.gov portal covers notary commissions

## 现场办理地点

- **Washington** — ONCA, 899 North Capitol Street, NE, Suite 8100, Washington, DC 20002 接受无需预约到访办理。 办公时间: Walk-in hours 9:00 AM–1:00 PM Mon–Fri (except holidays) 当日办结服务: 提供此服务。 No appointment needed, first come first served; same-day processing

## 费用

- **$15.00 USD** 每份文件 — "$15 per document" (apostilles, Department Head Certificates, Foreign Certificates)

## 如何付款

- **邮寄:** 支票或汇票
- **现场办理:** 支票, 汇票、或银行卡付款
- **付款抬头（收款人）:** DC Treasurer — 请按原文一字不差地抄写。
- 付款须开自美国银行账户。
- Walk-in: checks, money orders, Visa, MasterCard, Discover, American Express (credit card in person); mail: "only checks or money orders" from a US financial institution in US dollars, payable to "DC Treasurer"

## 文件邮寄地址

- **邮寄地址:** DC Office of Notary Commissions and Authentications (ONCA), 899 North Capitol Street, NE, Suite 8100, Washington, DC 20002
- **来源原文:** Authentications page also prints "NW" in one instance; NE is the address used everywhere else

## 办理时长

- **邮寄办理:** Mail: FAQ says "2-3 business days," Authentications page says returned to mail "in five (5) business days from receipt of completed requests"
- **现场办理:** Walk-in: same day, "usually takes about 5-10 minutes"
- No paid expedite option stated

## Checking status and verifying an apostille

- 该机关未公布可供公众查询的核验登记系统。这并不代表附加证明书无法核验——请向该机关询问其核验方式。

## 远程在线公证

- 此地允许远程在线公证。
- **法律依据:** D.C. Code § 1-1231.13a (RULONA, D.C. Law 22-189), remote provisions added/amended by D.C. Law 24-178 (eff. Sept. 21, 2022) and D.C. Law 24-194 (eff. Dec. 13, 2022); implementing rules 17 DCMR 2416–2417 (per NNA, adopted Nov. 3 — year not confirmed on an official page) (unverified)
- **公证员须登记的事项:** No separate RON endorsement, but before the first remote act the notary must notify the Mayor and identify the technologies to be used (D.C. Code § 1-1231.13a(k); 17 DCMR 2416.1). Separate electronic-notary endorsement: $30 application fee + mandatory training (per NNA/E-Notary Handbook)
- **如何核实签署人身份:** Personal knowledge (§ 1-1231.06(a)); or credible witness on oath/affirmation; or at least 2 different types of identity proofing (§ 1-1231.13a(b)(1)). Per 17 DCMR 2417 (via NNA): credential analysis (automated authenticity testing + visual comparison) and dynamic KBA (min. 5 questions, 80% pass, 5-minute window). Biometric not specified
- **标准公证行为：** $5.00 USD
- 此处未记录远程公证行为的收费上限。未记录上限并不等于“没有上限”——具体原因见下方备注。
- **来源原文:** Max RON fee: no statutory cap found; E-Notary Handbook: e-notaries "may charge a reasonable fee based on the electronic technology... if that fee is agreed to in advance... and itemized separately" (unverified whether a numeric RON cap exists in rules). "Notaries may charge up to $5 per notarial act" (ONCA FAQ). Conflict: DC E-Notary Handbook (July 2023) states "E-Notaries cannot notarize documents remotely in Washington, DC. At present, all parties are required to be present" — predates the remote-notarization rulemaking cited by NNA (17 DCMR 2416–2417); statute clearly authorizes remote acts

> **RCW 42.45.230(5):** 我不是本州执业律师。我无权起草法律文件、就法律事务(包括移民)提供建议,也无权为这些活动收取费用。
