Your passport and file are handled by our own team, on-site. Zero offshore subcontracting, guaranteed.

We guide you in English at every step — from the W-7 form to the final IRS letter.
Your gateway to US credit
Without an ITIN, no access to US credit cards (Amex, Chase, Capital One...). It's the first step to building your US credit history and much more.
The ITIN (Individual Taxpayer Identification Number) is your personal tax identification number in the United States. Essential for accessing US credit, opening certain bank accounts, and fulfilling your IRS tax obligations. Altixia handles the entire procedure for you — in-house, no outsourcing.
- Complete IRS file prepared by our team in 24 to 48 hours
- Direct CAA certification — your passport stays with you
- Tracking until the IRS letter is delivered
- Support in English at every step
- Access to US credit cards once your ITIN is granted
- IRS processing time: ~7 weeks after complete submission
