The IRS creates the name control from the legal name listed on the Form SS-4, Application for Employer Identification Number, according to the Internal Revenue Service.
IRS name control and EIN matching
The Internal Revenue Service defines the name control as a code derived from the legal name listed on the Form SS-4, Application for Employer Identification Number, as stated on their page "Using the correct name control in e-filing corporate tax returns." The IRS checks the name control together with your Employer Identification Number against its e-file database. When you applied for your Employer Identification Number, you provided the name of your business, which is used to assign your name control and will remain so unless you request a name change, according to the Internal Revenue Service. This means the name control is not a dynamic field that updates automatically if you change your business name in your accounting software; it remains tied to the original application data until a formal request for a name change is processed by the IRS.
For tax preparers and business owners filing electronic returns, understanding this static nature is critical. The e-file system uses the name control to verify that the business name in the return header matches the name associated with the EIN in the IRS database. If the name control in your e-file header does not match the IRS record, the system may reject the return. The IRS states that the name control is assigned based on the name provided during the EIN application process, and this assignment persists until a name change is requested, as detailed on the Internal Revenue Service page "How your name control is assigned."

How the IRS assigns and verifies name controls during e-file processing
The verification process begins when a return or extension is filed. According to the Internal Revenue Service, the agency checks whether a name/TIN combination is correct by matching it against a file containing all employer identification numbers (EIN) issued by IRS. This initial check ensures the submitted data aligns with the central registry of issued EINs.
Once the name/TIN combination is validated against the EIN file, the system proceeds to the next stage. The name control listed on the return/extension is then compared to the name control on the IRS file, as reported by the Internal Revenue Service. This comparison isolates the specific formatting of the business name to ensure it matches the recorded standard.
For electronic filings, specific header requirements apply. In e-file, a taxpayer’s Employer Identification Number (EIN) and name control in the Return Header must match the data in the IRS e-file database, according to the Internal Revenue Service. The EIN and name control in the Return Header must match the data in the IRS e-file database. If these elements do not align with the database records, the system flags the discrepancy.
You should verify that your e-file header data mirrors the IRS file exactly before submission. Check that the EIN and name control in your software’s Return Header match the values in the IRS database.

Step-by-step guide to calculating your specific name control

1. Identify the source of the legal name. Locate the legal name exactly as it appears on your Form SS-4. This document provides the authoritative name used to derive the code.
2. Exclude spaces and blanks. The resulting name control contains no spaces; keep the words separate when deciding whether to include "The." As stated by the Internal Revenue Service, "Spaces or blanks are not part of a name control." Do not include any blank characters in your calculation.
3. Handle the word "The." Apply the specific rule for leading articles. According to the Internal Revenue Service, "Include the word “The” when it is followed by only one word." If "The" is followed by two or more words, exclude it from the calculation.
4. Apply ethnic surname rules. If your business name includes Hispanic, Asian, or other ethnic surnames, consult the specific exhibits provided by the IRS. The Internal Revenue Service directs readers to "see the Exhibits at the end of Publication 4164, Modernized e-File (MeF) Guide for Software Developers and Transmitters" to help determine the correct name control.
5. Verify against the IRS file. Compare your calculated code against the name control stored in the IRS e-file database. This step ensures your manual calculation matches the official record associated with your EIN.
6. Match the e-file header. Enter the verified name control into the e-file header of your tax software. The name control entered in the header must match the name control in the IRS record.
7. Contact for mismatches. If your calculated code does not match the IRS file or causes a rejection, contact the appropriate IRS support channel. Use the contact information provided in your rejection notice to resolve the discrepancy before resubmitting.
8. Use software-specific help. Consult the documentation for your specific tax preparation software if you encounter errors during the e-file process. Software providers often include guides that explain how their interface handles name control inputs and validation.
For corporate returns, the Internal Revenue Service advises reviewing the Business Name Control matrix in FAQ 5 for business name control rules.
