**Please note that due to the Coronavirus Pandemic, the Internal Revenue Service (IRS) is delayed with providing Tax ID Numbers (EIN). They are now accepting phone calls and receiving faxes. We are working diligently to obtain Tax IDs for our clients but there will be significant delays for those without a U.S. social security number or with a non-US address. We appreciate your patience during this time.**

After forming a Delaware corporation or LLC, the next step is to obtain a Federal Tax ID Number (also known as an Employer Identification Number or EIN).

Think of the EIN as the social security number for your company. It is a nine digit number that is issued by the IRS (for example, 01-2345678).

Just as a social security number is important for U.S. citizens to have, the Federal Tax ID Number is necessary for an LLC or corporation to lawfully conduct business activities, especially if you're operating a business in the United States. All U.S. companies are required to have an EIN to open a U.S. bank account, obtain loans, hire employees and more.

The EIN is valid for the life of the company. However, if your business changes its entity type (for example, it changes from an LLC to a corporation), a new Federal Tax ID Number is typically required.

How Do You Apply for an EIN?

We offer an inexpensive service to assist you with obtaining a Federal Tax ID for your company from the IRS. This fast and easy service allows you to avoid dealing with the often-confusing IRS forms and procedures, and also includes professional customer support.

Our processing time for EIN orders will depend on how we are able to submit your filing to the IRS. If a filing contains a non-U.S. address or the member does not have a ITIN (Individual Tax Identification Number) issued by the United States, it must be submitted by fax or scan.

All other filings will be processed online unless the EIN cannot be obtained, in which case it will have to be faxed. Processing times begin after we receive the signed SS-4 form.

Orders submitted online to the IRS: 3 - 4 business days

Orders submitted by fax to the IRS: *See note in red at top of page*

Please note that if you do not have a U.S. Address or U.S. Social Security Number, you will be required to provide a copy of the passport or government-issued ID for the person listed as the "responsible party" after submitting your order.

Responsible party has U.S. address and valid SSN/ITIN
Responsible party does not have U.S. address or valid SSN/ITIN


If you're forming a new company with us, you can save time and request that we obtain the EIN for you when we file your corporation or LLC.

When you fill out our company order form, simply select that you would like for us to obtain your Federal Tax ID number and we'll take care of the rest.

What do you do if you lose your EIN?

It's not uncommon for an EIN to get misplaced. If you can't locate the Federal Tax ID Number for your company, there are several ways to find it.

You can contact the IRS directly at (267) 941-1099 (if you are not in the U.S.) or at 800-829-4933 (if you are in the U.S.) and request a replacement confirmation letter called a 147C letter; the IRS will fax it to you upon request.

If we obtained the EIN number on behalf of your company, feel free to request that the 147C letter be faxed to us at (302) 645-1280. Once the fax has been received, we will email the letter to you as a courtesy.

Unfortunately, we are not able to contact the IRS on behalf of your company due to its strict privacy policies. Be prepared for lengthy hold times when you call the IRS; our clients have reported that hold times tend to be shorter the earlier in the morning you call, so try calling as close to 9 AM as possible.  

If you have any questions about obtaining an EIN for your Delaware company or requesting a 147C letter from the IRS, feel free to contact us with your questions at 800-345-2677 or info@delawareinc.com.


How can you look up any company’s EIN?

Sometimes, individuals or businesses want (or need) to locate the EIN number for another business, such as for tax reporting or simply to validate information.

In many cases, if this is a company you are dealing with in a business capacity, you can simply ask them for their EIN number. Generally, if you will be making payments to them, you will want to request a w-9 form from them, which notes the EIN number.

If you are not working with them directly, there are often other ways to locate a company’s EIN. For instance, if the company is publicly traded, you can use a searchable public database on the SEC website to find documents that will show any company’s EIN number.

For other companies, you may still be able to find an EIN by searching the internet for official documents that may be available to the public, such as filings required by their local municipalities or for an industry permit.

As a last resort, you can use a service such as Credit.net to find and purchase a business credit report that typically includes the EIN number. We recommend verifying you will receive the information you’re looking for prior to making payment to any such service.
