# CARF Requirements in the EU

## What is CARF?
CARF is the OECD’s Crypto‑Asset Reporting Framework. It’s a global tax-transparency standard that requires crypto-asset intermediaries to identify their consumers’ tax residencies and report their consumers’ crypto transactions to tax authorities, which then automatically exchange that information across borders.
## Why does it matter in the EU?
The EU has chosen to implement CARF through its own law, called DAC8 (Council Directive (EU) 2023/2226), aligning EU rules with the OECD standard and the updated Common Reporting Standard (CRS).
## What does this mean when making an onramp purchase in the EU?
When completing the Crypto Onramp checkout, in addition to our KYC requirements, we'll prompt you to provide:
* Your country of tax residence
* Your tax resident number (TIN)
* CRS & CARF Declaration
### What if I don’t have a TIN?
Providing a TIN is a requirement for using Crypto Onramp. If you do not have a TIN,  you will not be able to complete any crypto onramp purchases.
