Short answer
Digital Signature & Electronic Document Certification is available in all 77 Thai provinces, using the route that fits each area: an in-office appointment, a travelling team, or courier handling with a video identity check. Usually 2–5 business days before any further certification layers. Start by sending document photos for review so no courier round or trip is wasted.
Three routes — which one fits your area
| Route | Best for | Note | Provinces |
|---|---|---|---|
| In-office appointment | Within same-day travel of one of our offices | Signatory appears in person before the attorney | 27 |
| We travel to you | Multiple signatories, or executives who cannot travel | Booked ahead; the document set is verified before we depart | 6 |
| Courier + video identity check | Provinces far from our offices | We review document photos on LINE before anything ships, so no courier round is wasted | 44 |
Documents to prepare
- The original PDF with the digital signature still embedded — not a printed-and-rescanned copy
- Provenance evidence such as the issuing system's email or verification link
- Passport or Thai ID of the signatory
- The receiving authority's rule on digital versus paper acceptance
- Any verification code the issuing system provides
How the process runs
- 1.Verify the digital signature integrity and the file's provenance
- 2.Confirm with the receiving side which form is accepted: digital, certified print-out, or both
- 3.Produce a printed set with a certification that references the source file and how to verify it
- 4.Run the required certification layers such as notarisation and consular legalisation
- 5.Deliver the digital file and/or hard copies in the format requested
Pitfalls that get work rejected
- Printing and rescanning, which destroys the digital signature and the audit trail
- Assuming every authority accepts digital files when many still require certified hard copies
- Sending a file whose verification link has expired, leaving the receiver unable to confirm it
We check whether your file can still prove its provenance and whether the digital or paper route fits — choosing wrong at the start usually costs a full round. If you would rather not handle the runaround yourself, send document photos to LINE @thainotary or call 094-8958999 — our team of 15+ years assesses the matter and manages it end to end.

Can I complete this without travelling to Bangkok?
In most cases yes. Any matter that does not legally require the signatory to appear before the attorney can run end-to-end by courier. Where an in-person signature is required, we either book the nearest office or send the team to you.

Usually 2–5 business days before any further certification layers. That window excludes inter-province transit and depends on the queue at the authorities involved at the time. We give you an assessed timeline before work begins.
