How Long Does It Take to Get an EIN? (Timeline by Application Method)
Gary Gal
In my work helping businesses get started, clients constantly ask how long it takes to get an EIN. At Andemax, we’ve seen delays mostly due to choosing the wrong application method or submitting incomplete forms.
The timeline depends on your chosen application method, with online applications providing immediate issuance and mail requests taking up to several weeks. Fax submissions usually take about four business days, while international applicants can complete phone requests during the call.
Knowing these timelines lets you plan your business setup efficiently and avoid unnecessary waiting. Next, read the key takeaways below to quickly understand what actually impacts your EIN timeline and how to avoid delays.
Key Takeaways
Your filing method controls your timeline. Online is immediate, fax takes a few days, and mail takes weeks. Choose wrong, and you delay banking and tax setup.
Errors on Form SS-4 cause most delays. Wrong entity details or taxpayer IDs trigger rework. Fixing mistakes often takes longer than filing correctly.
Entity classification mistakes slow approvals. Small mismatches can trigger a manual IRS review. This can stall your EIN without clear notice.
Accuracy drives speed. Complete and verified information reduces IRS follow-ups. Clean submissions move faster every time.
Now, let’s take a closer look at each application method and where delays actually happen in practice.
What Actually Affects EIN Processing Time?
EIN processing time refers to the duration required for the IRS to review and assign a business identification number. This timeline varies based on submission method, data accuracy, administrative workload, and verification requirements.
The following factors outline how each element directly influences processing speed:
Factor | How It Affects Your Timeline |
Application method | Determines if you get your EIN instantly or wait weeks |
Accuracy of information | Errors can delay processing or require resubmission |
IRS workload | High demand can slow down processing times |
Business structure | Some entities need extra review before approval |
Time of submission | Late or weekend submissions may add delays |
Because many of these factors are directly tied to how the application is completed, understanding the correct process is critical. For a detailed walkthrough, refer to our guide on how to apply for an EIN for first-time business owners.

Online Application Timeline
Online applications are the fastest way to get an EIN if you meet eligibility rules. This method works best for businesses located in the United States. You can complete the process in one session if you prepare your information ahead of time.
Immediate Issuance
When you apply online, your EIN is issued right after you finish the form. This makes it the best option if you need your EIN quickly. However, you must complete the application in one sitting, or the session will expire.
What you should expect with online applications:
EIN is issued immediately after submission
Available only during IRS business hours
Must complete the form in one session
Limited to one EIN per day per responsible party
Apply early in the day during IRS business hours to reduce system congestion and improve processing stability.
Tips for Avoiding Errors
Even though online applications are fast, small mistakes can still cause problems later. Taking a few minutes to double-check your information can save you time and stress. This step is simple but often overlooked by new business owners.
Quick checklist before submitting:
Confirm your legal business name matches official documents
Double-check Social Security Number or ITIN
Use the correct business structure
Ensure your mailing address is accurate
Always cross-check your EIN application details against official business registration documents before submission to prevent validation issues.
Fax Application Timeline
Fax applications offer a balance between speed and flexibility. This method works well if you cannot apply online or need extra time to review your form. It is also a good backup option if the online system is unavailable.
Typical Processing Time
Fax applications usually take about four business days to process. This timeline can change depending on the IRS workload and the accuracy of your form. If there are errors, the IRS may contact you, which can delay the process.
Fax timeline overview:
Step | Time Estimate |
Submit fax | Day 1 |
IRS processing | 3–4 business days |
EIN issued | Around Day 4–5 |
Plan your fax submission on non-peak weekdays since IRS processing queues tend to be lighter and more consistent then.
How to Prepare Your Fax Submission
Preparation is key when using a fax, because errors can slow everything down. You should treat this method like a formal submission and review it carefully. A clean and complete form improves your chances of faster processing.
Steps to prepare your fax application:
Download and complete Form SS-4
Review all entries for accuracy
Include a return fax number
Send to the correct IRS fax number
Keep a copy for your records
Always verify the IRS fax number for your specific state before sending Form SS-4.
Mail Application Timeline
Mail and phone applications are slower but necessary in certain situations. These methods are often used by international applicants or those without access to online tools. While slower, they are still reliable if done correctly.
Why Mail Takes the Longest
When you submit your application by mail, the IRS must receive, review, and process the form manually. Each step adds additional time to the process. As a result, mail applications often take several weeks.
Reasons mail processing takes longer:
Physical delivery time
Manual data entry by IRS staff
Higher risk of missing information
Backlogs during busy filing periods
Because of these factors, mail should be your last option if speed is important.
How to Prevent Weeks of Delay
While mail applications are slower, you can still reduce unnecessary delays. Careful preparation helps ensure the IRS processes your request without problems. Paying attention to small details makes a big difference.
Steps to minimize delays:
Use the latest version of Form SS-4.
Write clearly and avoid incomplete fields.
Confirm the correct mailing address for your location.
Keep copies of the completed form for your records.
Taking these precautions helps protect your application from avoidable processing issues.
Phone Application for International Applicants
International applicants often cannot use the online EIN system. Instead, they can apply by phone through a dedicated IRS line. This process allows eligible applicants to receive an EIN during the call.
Who Qualifies for Phone Applications
Phone applications are designed mainly for businesses whose responsible party is outside the United States. These applicants typically do not have a Social Security Number or Individual Taxpayer Identification Number. The phone method provides an alternative way to complete the process.
Eligibility for phone applications:
Responsible party located outside the United States
Business requires an EIN for tax reporting
Applicant is prepared to provide business details during the call
If you meet these criteria, the phone option may be the fastest available method.
What to Expect During the Call
The phone application process involves speaking with an IRS representative. You must provide the same information required on Form SS-4. Having your documents ready helps the call move smoothly.
Phone application workflow:
Call the IRS international EIN line.
Provide your business information to the representative.
Confirm the responsible party’s details.
Receive your EIN during the conversation if approved.
Preparation makes the call faster and reduces the risk of needing additional follow-up.

Conclusion
From a professional standpoint, understanding how long it takes to get an EIN is less about speed and more about method selection accuracy. Most delays occur not at the IRS level, but from preventable filing errors and poor timing choices.
An often-overlooked insight is that mismatched entity classification triggers manual IRS review, even when all other data is correct. This single issue quietly extends processing time far more than most applicants expect.
The cost of error is delayed banking, payroll setup, and tax registration, while correct filing ensures immediate operational readiness and compliance confidence. For a confidential review and guided filing support, contact our Great Neck Estates team at Andemax on (800) 344-5226.
