About us
ITIN help for people outside the U.S., without mailing your passport
ITINNumber.io is a private service that prepares, certifies and files Form W-7 ITIN applications and renewals for non-U.S. applicants, working as an IRS Certifying Acceptance Agent. We're focused — this is all we do here — and we'd rather lose a sale than help someone who's better served elsewhere.

Why this service exists
For years our team has helped non-U.S. founders form U.S. LLCs and get their EINs, through FormLLC and EINNumber.io. Many of those clients then needed an ITIN of their own — for a partnership return, a treaty claim or a spouse on a joint return — and asked how to get one without posting their passport to the IRS.
Applying yourself means mailing Form W-7 with your original passport, or a copy certified by the office that issued it, and waiting weeks to get it back. Notarized copies aren’t accepted. Small mistakes — a name that doesn’t match, the wrong reason box, a missing exception document — end in a CP567 rejection, and the wait starts again.
A Certifying Acceptance Agent removes the hardest part: the agent examines your original passport and sends the IRS a certified copy instead. ITINNumber.io is the same team’s ITIN service, built around that role, with the same plain-English, no-surprises approach our clients know from our other services.

Who’s behind ITINNumber.io
The same team that runs EINNumber.io and serves clients as FormLLC on Trustpilot and as Tousif Akram on Fiverr. Same people, same process — ITINNumber.io is where we focus on ITIN applications alone.
Based in India.

Our CAA status
We work as an IRS-authorized Certifying Acceptance Agent. Our listing details are available on request, and you can read how the program works on the IRS Acceptance Agent Program page (opens in a new tab).
Being a CAA means we can examine your original documents and certify copies for the IRS. It doesn’t make us part of the IRS, and the IRS still decides every application.

The same four steps for every client. You always know what stage you’re at, whose clock is running and who is handling it.
Day 1
Eligibility check
You tell us why you need an ITIN and upload your passport. We confirm you qualify and whether you need a tax return or an exception — or tell you honestly that you don’t need us.
At a time you choose
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.
Within 1–3 business days
W-7 prepared and filed
We prepare the W-7, you review and sign it, and we file it with the IRS together with the certified copy and your return or exception documents.
IRS: 7 weeks (9–11 weeks from January 15 to April 30 or from abroad)
Tracked until assigned
We follow the application through the IRS wait, follow up once the window has passed, and help you read the CP565 that confirms your ITIN.
How we run this business
Honesty first
If you don’t need an ITIN — many platforms only need a W-8BEN, and an LLC can get its EIN without one — we tell you before you pay.
Direct communication
No ticket queues, no chatbots. You talk to the people handling your application, and we aim to reply within one business day.
Specialists, not generalists
On ITINNumber.io we do one thing — Form W-7 applications and renewals for people outside the U.S. Tax returns go to an enrolled agent or CPA.
Realistic expectations
We show two clocks on every page: our 1–3 business days and the IRS’s 7 weeks or more. There are no IRS shortcuts, and we won’t pretend otherwise.
How we keep our information accurate
Our guides and service pages are written by the people who prepare these applications — and every IRS fact on them is checked against the IRS itself.
- IRS addresses, phone numbers, processing times, document rules and W-7 exceptions come from the official IRS pages listed below. Last checked .
- We re-check them whenever the IRS revises Form W-7 or its instructions, and at least every quarter — the IRS changes procedures without notice.
- We keep IRS rules separate from our own experience. When something is our observation rather than an IRS rule, we say so.
- Where a question is really about tax, law or immigration, we say that too and point you to a qualified professional.

“Super service! I needed an EIN for my LLC, and Tousif handled everything smoothly and professionally. He was responsive, answered all my questions clearly, and delivered the EIN with the official 147C confirmation letter faster than expected. He also made sure everything was done correctly and in my name. Thank you!”
The things we explicitly say no to
Clear boundaries are part of the service. Here is what you will never get from us.
Guarantee approval or dates
The IRS decides every application and sets its own timeline. We prevent avoidable mistakes — we can’t promise an ITIN, a week or a date.
Sell you an ITIN
The ITIN comes from the IRS, free. Our fee is for the work around it.
Pretend to be the IRS
We are a private service that works as a Certifying Acceptance Agent under an agreement with the IRS. We are not the IRS or any government agency.
Give legal or immigration advice
We help with ITIN applications. An ITIN doesn’t change immigration status, and for legal or complex tax questions we refer you to professionals.
Take cases that don’t need us
If you can get an SSN, don’t need an ITIN at all, or would do better applying another way, we’ll tell you.
Want a straight answer about your case?
Tell us your situation and we'll tell you honestly whether you need an ITIN at all.

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.
