Start application

Tell us about your ITIN application

Four short steps (about 5 minutes), then upload your passport and pay securely by Razorpay. We book your CAA video verification and your client dashboard tracks everything after that.

What happens next

Upload your documents
Right after you save the application, upload a clear scan of your passport, plus your tax return or exception documents if you have them. Missing something? You can add it later.
Pay securely
Razorpay’s secure checkout opens for the fixed package price. Debit and credit cards accepted; PayPal if your card doesn’t work.
Specialist review
We check your eligibility and documents within one business day and email you if anything is missing.
CAA video verification
Our Certifying Acceptance Agent examines your original passport on a short recorded video call and certifies a copy. You don’t mail your original passport to the IRS.
W-7 prepared and filed
You review and sign the W-7, we file it with the IRS and keep you updated until your ITIN is assigned.

Your passport and details are encrypted in transit, used only for your application, and never sold.
Full refund if you change your mind before we file your W-7 with the IRS.
Priority and Complete include one free resubmission if the IRS rejects the application.

Two clocks apply to every ITIN. Ours: we prepare and certify your application within 1–3 business days of receiving your documents and completing the video verification. The IRS’s: it says to allow 7 weeks, or 9–11 weeks from January 15 to April 30 or when you apply from abroad — and nobody can speed that up. We track your application through the IRS wait, follow up once the IRS window has passed, and tell you as soon as your ITIN is assigned. All prices are listed in USD with no hidden fees, and payments are made securely by debit or credit card through Razorpay. The IRS charges nothing for the ITIN itself.

ITINNumber.io is a private service provider that works as an IRS Certifying Acceptance Agent under an agreement with the IRS. We are not the IRS, not part of the U.S. Department of the Treasury or any government agency, and not a law firm, CPA firm, or bank. The IRS issues ITINs free of charge to applicants who apply directly. Our fees cover professional preparation, document certification, filing, and follow-up — not the ITIN itself. The IRS decides every application and sets its own processing times, which cannot be guaranteed or shortened.
