Check EIN Application Status (2026) Guide

The IRS issues an Employer Identification Number (EIN), a 9-digit federal tax ID in the format XX-XXXXXXX, through Form SS-4. After you submit the form, the IRS gives no automated way to watch its progress. Online filings finish in the same session. Fax and mail filings sit in an IRS queue with no tracking number. Your only official status channel is the phone. This guide explains exactly when to call, what the IRS asks, what each status answer means, and how a non-resident applying without an SSN confirms an EIN. It also covers how ein.so removes the phone step by tracking your application for you. For the full filing process, see how to get an EIN.

Timelines

When Should You Check Your EIN Status?

You should check your EIN status only after the processing window for your filing method passes. Online filings finish instantly, so no check is needed. Fax filings take 4-7 business days. Mail filings take 4-6 weeks. Calling earlier wastes a long phone call.

The processing clock starts the day the IRS receives your Form SS-4, not the day you send it. Peak season from January through April adds 2-5 business days to fax and mail timelines. The table below shows when each method produces a checkable status.

Non-residents without an SSN cannot use the online tool, so they file by fax and follow the 7-business-day window. See EIN processing time for a full breakdown of each method's speed.

Delays

What Causes EIN Application Delays?

EIN application delays come from peak season volume, incomplete Form SS-4 fields, a wrong fax number, or a duplicate submission. Each cause adds days or forces a refiling. Most delays trace to errors a non-resident makes on the SS-4 address or responsible party lines.

The IRS processes a clean fax SS-4 in 4-7 business days. A single error resets that clock. The table below lists the four most common delay causes and their fixes.

Non-residents face the longest delays from address formatting. A 5-digit foreign postal code and city do not map cleanly to the SS-4 layout, and the IRS silently rejects malformed international addresses. ein.so reformats your address to an IRS-accepted style before filing. See EIN for non-residents and EIN without an SSN.

Non-Residents

How Do Non-Residents Check EIN Status Without an SSN?

Non-residents check EIN status by calling the international IRS line at 267-941-1099 and referencing the passport number entered on Form SS-4 Line 7b. No SSN or ITIN is needed to file or to verify. The IRS matches the application by entity name and responsible party.

The IRS online EIN tool requires an SSN, which is why non-residents file by fax to 855-215-1627 and follow the 7-business-day window. When you call, the agent confirms the EIN against your Line 7a responsible party name and your Line 7b passport number.

A non-resident pays $0 to the IRS for the EIN itself. ein.so charges $49 (Standard, 4-7 business days) or $97 (Express, 2-3 business days) to prepare, file, track, and deliver your EIN, so you skip the international call. Compare costs on the EIN cost page.

Next Steps

What Should You Do After Your EIN Status Is Assigned?

1. Request Letter 147C — written proof of your EIN that banks accept in place of the CP 575
2. Open a US bank account — Mercury, Relay, and Wise accept non-resident LLC owners with an EIN and passport
3. File your BOI report — required for most LLCs, filed free at fincen.gov/boi
4. File Form 5472 — annually for foreign-owned single-member LLCs, $25,000 penalty for non-filing
5. Confirm tax duties with a CPA — ein.so does not provide tax advice; pricing details on EIN cost
