# Required documents

> Which files to upload during the incorporation checklist and how to prepare them.

Last updated: 2026-07-10 · [HTML version](https://docs.korp.ph/required-documents) · Korp Docs

During the **Supporting documents** step of your [incorporation checklist](/incorporation-checklist), you'll upload identity and address documents Korp needs to complete your SEC filing and eSECURE registration.

## Why we need these

The SEC and eSECURE require verified identity for everyone named on your incorporation documents. Korp collects these upfront so filing isn't delayed later.

## Per incorporator

For **each incorporator** listed in your capital structure, upload:

| Document | What to provide |
| --- | --- |
| **Valid government-issued photo ID** | Philippine passport, PhilID, driver's license, or other government ID with a clear photo |
| **TIN proof** | TIN card, BIR Form 1903/1904, or other official proof of tax identification |

### Foreign incorporators

If an incorporator is not a Philippine resident, a **passport** is usually the right government ID. They still need a Philippine TIN for SEC purposes — see [TIN registration for foreign incorporators](/tin-foreign-incorporators) for how that works.

## Company-level documents

Upload **proof of registered office address** — for example a lease contract, utility bill, or letter showing the address that will appear on your SEC records.

## File requirements

- **Formats:** PDF, JPG, PNG, or WebP
- **Size:** up to 10 MB per file
- **Quality:** full document visible, readable text, no heavy cropping of ID photos

## After you upload

Our team reviews each file. If something isn't acceptable, the upload is marked **Rejected** with a short note — replace the file and we'll review again. Uploading documents does not use the same “Request changes” flow as editing text fields; just upload a new file.

## Privacy

Documents are stored securely and used only for your incorporation filing. They are not shared outside what SEC registration requires.
