ITIN Number Example: What an ITIN Looks Like (2026)

What Is a Standard ITIN Number Example in 2026?

A standard ITIN looks visually similar to a Social Security Number: 9 digits printed in a 3-2-4 pattern. The structural rule that separates an ITIN from an SSN is the first digit: an ITIN always starts with 9, and an SSN never does. The IRS assigns the remaining digits according to internal ranges.

Real issued ITINs are protected under 26 U.S.C. Section 6103 and cannot be published. Format samples use placeholder digits to illustrate the structure without disclosing private taxpayer data. See the underlying ITIN Number Format for the rule set.

What Are the Valid ITIN Middle-Digit Ranges?

The IRS uses the middle two digits (positions 4 and 5 of the 9-digit number) to mark which assignment cohort an ITIN belongs to. 4 ranges are valid in 2026.

Numbers outside these ranges are not valid ITINs. If a number claims to be an ITIN but uses a middle pair outside 50-65, 70-88, 90-92, or 94-99, it is either an SSN, a typo, or fabricated.

How Does the ITIN Example Compare to an SSN Example?

Both ITINs and SSNs are 9-digit numbers printed in 3-2-4 groupings, so visually they look similar. The difference is in the digit values, not the layout.

• ITIN example: 9XX-7X-XXXX — leading 9, middle pair in 50-65/70-88/90-92/94-99.
• SSN example: XXX-XX-XXXX — leading digit 0-8, never 9.
• EIN example: XX-XXXXXXX — 2-7 grouping, never 3-2-4.

The full side-by-side comparison lives on ITIN vs SSN and ITIN vs EIN.

Why Does Every ITIN Example Start With 9?

The Social Security Administration reserved the digit 9 for IRS use in 1996 when the ITIN program launched. By statute, the SSA does not issue Social Security Numbers that begin with 9. The IRS then uses 9 as the universal leading digit for all ITINs, which makes the two numbers programmatically distinguishable.

How Do You Verify That a Number Matches the ITIN Example Format?

A 4-step format check is enough to rule out transcription errors before submitting an ITIN to a bank, lender, or tax preparer.

1. Count the digits. Must be exactly 9.
2. Check the grouping. 3 digits, 2 digits, 4 digits with hyphens.
3. Verify the leading digit. Must be 9.
4. Verify the middle pair. Must fall within 50-65, 70-88, 90-92, or 94-99.
