Legal Name vs. DBA (Doing Business As) — What Should I Enter?

When completing your merchant application, it’s important to enter your Legal Name and DBA (Doing Business As) Name correctly.

Many merchants are unsure which name to use — especially if their business name appears differently on tax documents, bank accounts, signage, or marketing materials.

This guide explains the difference and how to complete this section accurately.


🏢 What Is a Legal Name?

Your Legal Name is the official name of your business as registered with the government.

This is the name that appears on:

  • Tax filings (EIN documentation, CRA/IRS records)

  • Articles of incorporation or business registration

  • Government-issued documents

  • Official contracts

✅ In most cases, your Legal Name should match your tax documents exactly.

Do not shorten, abbreviate, or modify this name unless it is written that way on your official registration documents.


🏷️ What Is a DBA (Doing Business As)?

Your DBA is the name your business operates under publicly.

This may be:

  • The name on your storefront

  • The name customers recognize

  • A shortened version of your legal name

  • A branded or trade name

Examples:

Legal Name

DBA

1234567 Ontario Inc.

Lakeside Marina

Smith Dental Professional Corporation

Smith Dental

International Union of Elevator Constructors Local 50

IUEC Local 50

Your DBA is what customers typically see on receipts or recognize as your business name.


💡 Why This Matters

The Legal Name is used for:

  • Compliance and underwriting

  • Tax reporting

  • Identity verification (KYC)

  • Matching government records

The DBA is used for:

  • Customer-facing receipts

  • Statement descriptors

  • Reporting visibility

If the Legal Name does not match official records, your application may be delayed due to verification issues.


⚠️ Common Mistake: Name Mismatches

Some merchants experience confusion because:

  • Their tax documents show one name

  • Their bank account shows a shortened or slightly different version

  • Their marketing materials use a branded name

Example:

A business may be registered as:

“International Union of Elevator Constructors Local 123”

But their bank account may show:

“IUEC Local 123”

In this case:

  • Use the full tax-registered name as the Legal Name

  • Use the shortened banking or operating name as the DBA

This helps avoid matching issues during underwriting and bank verification.


📝 How to Complete the Application Correctly

When filling out your merchant application:

Step 1: Enter the Legal Name

  • Copy it exactly as it appears on your tax registration documents.

  • Do not abbreviate unless the abbreviation is part of the registered name.

Step 2: Enter the DBA (if applicable)

  • Enter the name customers know your business by.

  • If your Legal Name and operating name are identical, you may enter the same name in both fields.


📌 Still Unsure?

If you’re not sure which name to use:

  • Refer to your tax registration or incorporation documents.

  • Check your EIN / CRA / IRS confirmation letter.

  • Contact your accountant or business administrator.

Entering the correct Legal Name and DBA helps prevent delays in processing your merchant application.
