1. Signatory / Account Holder (Authorized Representative)

The Signatory is the individual legally authorized to represent your organization — typically an Executive Director, CEO, or CFO.

Required Information:

• Full legal name (must match government ID)

• Date of birth

• Nationality / country of residence

• Legal home address (no PO Boxes)

• Last 4 digits of SSN (for U.S. citizens)

• Government-issued photo ID (passport or driver’s license – clear image, front and back)

• Email address and phone number

Best Practice:
✔ Use the same name and address that appear on your organization’s official registration documents.
✔ Avoid nicknames or shortened names, as Adyen will flag inconsistencies.

2. Nonprofit Organization (Legal Entity)

Required Information:

• Legal entity name (exactly as registered)

• EIN / Tax ID number

• Registered business address (no PO Boxes)

• Official website URL (optional but recommended)

• Certificate of incorporation or nonprofit registration document

• Recent bank statement (dated within the last 3 months) — must display:

  • The organization’s legal name

  • Account number

  • Bank logo

• Routing number and account number

• Short description of your organization’s purpose

Best Practice:
✔ Use a bank account owned by the nonprofit itself — not a fiscal sponsor, individual, or DBA.
✔ If operating under a fiscal sponsor, prepare a signed authorization letter from the sponsor allowing the use of the account.

3. Preparation & Technical Details

Before the onboarding link is sent, make sure to:

• Verify that the organization name, bank name, and signatory name match exactly across all documents.

• Disable any PDF password protection — Adyen cannot open encrypted files.

• Use accepted file types: .jpg, .png, .pdf (each under 10 MB).

• Complete the onboarding form in one sitting — it times out after approximately 30 minutes.
