Irish Document Apostille in the U.S. — 2026 Guide

Ireland and the United States are both parties to the Hague Apostille Convention, so the route is clean in both directions. A U.S. document used in Ireland needs an apostille from the Secretary of State of the issuing state. An Irish document used here is authenticated by the Department of Foreign Affairs in Dublin.

Quick facts

This matters most for the foreign birth register, where U.S. certificates from several generations have to be produced in acceptable form.

Fees breakdown

Long-form birth certificates are the ones Irish files generally require, not the short abstracts some U.S. states issue by default. Order the long form from the outset.

How to prepare a document for Ireland

1. Order the long-form certified copy from the issuing state office.
2. Notarise private documents first, since the apostille certifies the notary’s signature.
3. File with that state’s Secretary of State, or with Washington for federal records.
4. Check whether the Irish office receiving it wants the original or will accept a certified copy.
5. Send by a tracked service and keep the reference.

Required documents

• Original certified copy with signature and seal.
• Completed state authentication request and payment.
• Prepaid return envelope for mail filings.
• Photo ID for in-person service.

What the missions do

They provide consular assistance, information on citizenship and visas, and authentication of documents where it is needed. Passports are handled online and civil certificates come from the register office in Ireland.

Additional notes

Long form, not short form

This is the commonest document error in Irish files. A short-form certificate that omits parents’ details will not establish a line of descent.

Originals travel

The foreign birth register asks for original certificates, which are returned. Use tracked post in both directions and keep copies of everything first.

Order two copies

Where several generations are involved, a duplicate set saves months if anything goes astray.

Never apostille a photocopy

The certificate attaches to an original or a certified copy from the record keeper.
