How Do I Choose and Reserve a Corporate Name in Alberta?

Steps to choose and reserve a corporate name in Alberta

1. Decide between a named corporation and a number name. A number name is one that Corporate Registry assigns automatically (for example, 9999999 Alberta Ltd.). Choosing a number name means no NUANS report is required at all.
2. If you want a named corporation, order a NUANS name search report. NUANS (Newly Upgraded Automated Name Search) compares your proposed name against existing corporate names and trademarks.
3. Check your proposed name against Alberta’s identical-name rule. The Business Corporations Act prohibits a name identical to an existing Alberta corporation, or to an extra-provincial corporation registered in Alberta, unless that existing entity has been dissolved for six years or more.
4. Confirm the differences are more than cosmetic. Under the Business Corporations Regulation, changes like adding or removing punctuation or spacing, inserting or removing a year, or swapping the legal element (such as “Ltd.” for “Inc.”) do not make a name sufficiently different from an existing one.
5. Submit the NUANS report with your incorporation documents before it expires. The report reserves the name for 90 days, and the copy you file must be less than 91 days old.
6. Watch for name challenges after incorporation. Even once your corporation exists, another corporation can object to the Registrar of Corporations if it considers your name too similar to its own, and the Registrar can force a name change if the objection succeeds.

Named corporation vs. number name: what the choice actually affects

A named corporation lets you operate under a brand name from day one, but it requires a NUANS search and carries the risk that the name is rejected as too similar to an existing one, or challenged later by a competitor. A number name skips the search entirely: Corporate Registry assigns a numeric name (such as 9999999 Alberta Ltd.) with no name-similarity check needed at incorporation.

Why the 90-day / 91-day window matters

The NUANS report is only valid for 90 days from the date it is issued, and the copy filed with your incorporation documents must be less than 91 days old. If your incorporation paperwork, director approvals, or other steps take longer than expected, the report can expire before you file, meaning a fresh search may be needed.

Registering a trade name instead of incorporating

If you are not incorporating, but instead registering a trade name for a sole proprietorship or partnership in Alberta, the rules differ. Duplicate trade names are permitted to exist side by side (unlike corporate names, which cannot be identical to an existing corporation’s name). However, a trade name cannot end in “limited,” “incorporated,” or “corporation” (or their abbreviations), because that would falsely suggest the business is incorporated when it is not.

Extra-provincial corporations registering in Alberta

If you are registering an out-of-province corporation to carry on business in Alberta rather than incorporating a new one, additional naming rules apply. Under the Business Corporations Regulation, an extra-provincial corporation cannot register, or carry on business under an assumed name, in Alberta if its name contains the word “Alberta,” or if it lacks a required legal element (such as “Limited,” “Incorporated,” “Corporation,” “Unlimited Liability Corporation,” or an approved abbreviation like “Ltd.,” “Inc.,” “Corp.,” or “ULC”), unless the Registrar authorizes a different legal element.

What happens if the Registrar orders a name change

Where a corporation has given an undertaking to dissolve or to change its name and fails to do so within the required time, the Registrar can step in directly. By written notice stating reasons, the Registrar can direct the corporation to change its name to one the Registrar approves, and the corporation then has 60 days from the date of that notice to comply.
