FEIN vs EIN: Quick Answer
Here’s the short answer:
FEIN and EIN are exactly the same number. There is no separate FEIN issued by the IRS.
The IRS officially uses the term Employer Identification Number (EIN). However, many organizations still use Federal Employer Identification Number (FEIN) because it emphasizes that the number comes from the federal government.
Whether a form asks for your FEIN or EIN, you should enter the same nine-digit number.
Quick Comparison Table
| Feature | EIN | FEIN |

What Is an EIN?
An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to identify businesses for federal tax purposes.
Think of it as a Social Security Number for your business.
Instead of identifying an individual, it identifies a business entity whenever it files taxes, hires employees, opens bank accounts, or completes other financial transactions.
A typical EIN looks like this:
12-3456789
Each business receives its own unique number.
Businesses commonly use an EIN for:
- Filing federal tax returns
- Reporting payroll taxes
- Hiring employees
- Opening business bank accounts
- Applying for business loans
- Establishing business credit
- Registering retirement plans
- Filing certain tax forms
Without an EIN, many businesses cannot complete these activities.
What Is FEIN?
FEIN stands for Federal Employer Identification Number.
Despite the longer name, it refers to the exact same identification number as an EIN.
The extra word Federal simply distinguishes the number from state-issued tax identification numbers.
Many organizations continue using FEIN because older forms and internal systems still use that terminology.
For example, you may see FEIN on:
- Payroll software
- Business loan applications
- Bank documents
- Insurance paperwork
- Accounting software
- Vendor registration forms
Although the wording differs, the number remains exactly the same.
FEIN vs EIN: Side-by-Side Comparison
Many business owners assume FEIN and EIN serve different purposes.
The table below shows why that assumption is incorrect.
| Feature | EIN | FEIN |
| Issued by the IRS | ✔ | ✔ |
| Nine-digit number | ✔ | ✔ |
| Used for payroll taxes | ✔ | ✔ |
| Used when filing federal tax returns | ✔ | ✔ |
| Required for many business bank accounts | ✔ | ✔ |
| Separate application process | ✘ | ✘ |
| Different identification number | ✘ | ✘ |
The comparison makes one fact clear:
FEIN and EIN are simply two names for one federal tax identification number.
Why Do Two Different Terms Exist?
Many people wonder why both names continue to appear on official paperwork.
The explanation is largely historical.
Years ago, businesses often used the term Federal Employer Identification Number to distinguish the IRS-issued number from state tax identification numbers.
As IRS publications evolved, the agency simplified the terminology and began using Employer Identification Number almost exclusively.
However, many private companies and government agencies continued using FEIN because:
- Older forms remained unchanged.
- Internal databases still used FEIN.
- Banks preferred distinguishing federal IDs from state IDs.
- Payroll systems adopted the older wording.
Today, you’ll encounter both terms regularly.
Fortunately, they always refer to the same number.
Why Businesses Need an EIN
An EIN plays an important role throughout the life of a business.
Even businesses without employees often obtain one because it simplifies many financial activities.
Some of the most common reasons businesses need an EIN include:
- Filing federal tax returns
- Hiring employees
- Paying payroll taxes
- Opening business checking accounts
- Applying for commercial loans
- Establishing business credit
- Registering with payroll providers
- Purchasing business insurance
Without an EIN, many financial institutions won’t allow a business to open commercial accounts.
Who Needs an EIN?
Not every business legally requires an EIN.
However, many do.
The IRS generally requires an EIN for businesses that:
- Hire employees
- Operate as corporations
- Operate as partnerships
- File employment taxes
- File excise taxes
- Maintain retirement plans
- Withhold taxes on income paid to nonresident aliens
Businesses that commonly obtain EINs include:
| Business Type | EIN Required? |
| Sole Proprietor (no employees) | Sometimes |
| Sole Proprietor (employees) | Yes |
| Single-Member LLC | Often |
| Multi-Member LLC | Yes |
| Partnership | Yes |
| Corporation | Yes |
| Nonprofit Organization | Yes |
Even when optional, many business owners still apply because an EIN helps protect personal information.
Real-Life Examples
Example 1: A Freelance Graphic Designer
Emma works alone as a freelance designer.
She has no employees, but she opens a business checking account.
The bank requests her FEIN.
Since she already obtained an EIN from the IRS, she provides that number.
The bank accepts it because FEIN and EIN are identical.
Example 2: A New Restaurant
A family opens a restaurant with eight employees.
Before running payroll, they apply for an EIN.
Later, their payroll software requests their FEIN.
They enter the same IRS-issued EIN, and payroll setup is completed successfully.
Example 3: An Online Clothing Store
Michael starts an online clothing business.
Although he has no employees, he wants to establish business credit.
He applies for an EIN to avoid sharing his Social Security Number with suppliers.
His suppliers ask for a FEIN.
Again, he provides the same EIN.
Common Mistakes People Make
Because the terminology is confusing, many business owners make avoidable mistakes.
Here are the most common ones.
Assuming FEIN and EIN Are Different
This is by far the biggest misconception.
Remember:
There is only one federal business tax identification number.
Applying for Multiple EINs
Some owners mistakenly believe they need both a FEIN and an EIN.
They don’t.
The IRS issues only one federal identification number for each eligible business entity.
Confusing an EIN With a State Tax ID
A state tax identification number is different.
An EIN handles federal tax reporting, while a state tax ID applies to state tax obligations such as sales tax or state payroll taxes.
A business may need both, but they serve different purposes.
Using a Personal Social Security Number When an EIN Is Required
Certain tax forms, payroll systems, and financial institutions specifically require an EIN.
Using a Social Security Number instead can delay applications or create compliance issues.
Conclusion
Understanding FEIN vs EIN is much easier once you know that both terms refer to the same identification number issued by the IRS. The only real difference is in the name—FEIN stands for Federal Employer Identification Number, while EIN is simply the shorter version, Employer Identification Number. Whether you are starting a business, hiring employees, opening a business bank account, or filing taxes, knowing the correct term helps you complete paperwork accurately and avoid unnecessary confusion. With this knowledge, you can confidently use FEIN and EIN in the right business and tax contexts.
