Build US Credit History with an ITIN: Amex, Chase & More

An Individual Taxpayer Identification Number (ITIN) exists for US tax reporting, but a meaningful side benefit for non-resident founders is that it can serve as the personal tax ID some US financial institutions accept in place of an SSN when opening a personal credit product. An EIN identifies your business; an ITIN is what lets a bank or issuer evaluate you personally — which matters for any credit product tied to your individual name rather than your LLC.

For founders with no existing US credit history, a secured credit card — where you deposit cash collateral that becomes your credit limit — is the most consistently accessible starting point. Several major US banks offer secured cards that accept an ITIN in place of an SSN during application, and consistent on-time payment activity on a secured card is what typically builds the credit history needed to qualify for unsecured products later.

Major unsecured card issuers vary significantly in how they handle ITIN applicants, and policies change over time — some evaluate ITIN applications case by case, often wanting to see an existing US banking relationship, a verifiable US address, and sometimes an existing relationship with that specific bank (an existing deposit account, for example) before approving an unsecured card. Treat any approval as issuer- and circumstance-specific rather than a guaranteed outcome — this is exactly the kind of claim where 'guaranteed approval' offers from unrelated third parties should be treated with skepticism.

An ITIN alone doesn't create credit history — it's simply the identifier that lets credit activity be tracked against you. What actually builds your file is time: how long accounts have been open, payment consistency, and credit utilization. International founders sometimes expect an ITIN itself to unlock credit immediately; in practice it's the prerequisite that lets the clock start, not a credit history shortcut.

HynoGo's certified ITIN application service (via IRS Certifying Acceptance Agent review) gets your ITIN issued without mailing your original passport to the IRS, and our US LLC formation includes the banking documentation (Operating Agreement, Banking Resolution) that most secured and unsecured card applications ultimately want to see alongside your ITIN.
