Why verification can be requested

Identity or account checks may be used to confirm account ownership, reduce identity fraud or meet applicable obligations. The actual need for verification depends on the service, legal requirements and the reason for the review.

This guide explains general verification considerations; it does not claim that every type of document or check is required by W9.

Check where a request comes from

Before providing documents or personal information, confirm the request through an official entry point on the correct website. An unsolicited message, unfamiliar domain or request made with unusual urgency can be a warning sign.

Do not send documents to an individual account claiming to represent support without independently checking its authenticity.

Accuracy and matching information

An inconsistency between account information and payment details can lead to questions. Use accurate information and describe any legitimate mismatch rather than submitting modified or borrowed documents.

Identity records belonging to another person should never be used to misrepresent account ownership.

Document privacy and limited disclosure

Identity documents can reveal sensitive personal information. Provide only what is necessary for a legitimate and properly explained purpose, using a secure channel.

Check the Privacy Policy for general handling principles and seek clarification about retention, access and deletion where applicable.

Transaction-related verification

A transaction review may require an account holder to identify a reference number, payment time or other non-secret information. Payment method conditions and other checks vary.

Do not provide card PINs, banking passwords, recovery phrases or one-time passcodes as proof of a payment.

If a verification review is delayed

Keep a record of when the request was made and which verified channel was used. Ask official support for the current status and any additional lawful information needed.

Avoid repeatedly sending sensitive files through unrelated channels or public social media messages.

Your rights and further reading

Data protection and identity rules vary by jurisdiction. Relevant privacy rights and retention duties depend on the operator, processing purpose and applicable law.
