Mail-In Service

Gulf Apostille provides a secure, convenient, and reliable mail-in service for clients anywhere in Texas or outside the state. Most of our clients use mail-in because it saves time and ensures their documents are processed accurately, without wasted trips or rejected paperwork. Follow the steps below to submit your document safely and efficiently.

1. Upload Your Document First (Required)

Before mailing anything, upload a clear copy of your document through our Start Your Apostille Request page. We review your file to confirm:

• Whether your document is eligible for apostille or authentication
• Whether notarization or a certified copy is required
• Whether it is a state-level or federal document
• Estimated processing time
• Estimated service and government fees

This step prevents delays, incorrect submissions, and rejected documents. It protects both your time and your original paperwork.

2. Review Time & Mailing Instructions

After you upload your document, we review it and send you:

• Your exact mailing address
• Any required forms (if needed)
• Payment instructions
• Packaging guidelines

Most documents are reviewed within 1–3 hours during business hours. Uploads sent after hours are reviewed the next business morning. We will clearly confirm whether your document is ready to mail and what the next step is.

3. Mail Your Original Document

Once you receive approval and instructions, mail your document using any trackable shipping method:

• USPS Priority or Express Mail
• FedEx
• UPS

We recommend placing your document inside a protective sleeve or folder and then inside a sturdy envelope. We will notify you as soon as your envelope arrives.

4. Processing Timeline

Processing times depend on the type of document and destination country. Typical timeframes are:

• Texas Apostille: approximately 3–5 business days
• State Authentication: varies by agency and country requirements
• Federal Authentication: depends on the specific federal office
• Consulate Legalization: varies by consulate and country

We will confirm the expected timeline for your specific document after review.

5. Return Shipping

When your document is complete, we return it using your preferred method:

• USPS Priority or Express Mail
• FedEx
• UPS
• International shipping (where available)

You may include a prepaid return label or envelope if you prefer. Otherwise, we can arrange return shipping and include it in your total.

Before sealing your envelope, make sure you include:

• Your original document (only after we approve it for mailing)
• Any forms or cover sheet we emailed you
• Your full name
• Your email address
• Your phone number
