Can I use REALTOR or MLS in my domain?

Generally you shouldn’t — and often you simply can’t. REALTOR® and MLS® are certification marks owned by the Canadian Real Estate Association, not generic words, and their use is restricted to CREA members operating within CREA’s trademark rules. Domains are where agents most often get this wrong, because the marks feel like plain vocabulary and registrars will happily sell you anything. Before building a brand on either word, read CREA’s current trademark policy — and for most agents, the stronger move is a domain that doesn’t need anyone’s permission at all. (General information, not legal advice.)

Whose words these are

REALTOR® identifies members of CREA; MLS® identifies the cooperative listing systems boards operate under CREA’s mark — the full picture is in the MLS glossary entry. Certification marks work differently from ordinary branding: they certify membership and origin, which is why non-members cannot use them at all and members can only use them in ways that preserve what the marks certify. A domain is a high-visibility, permanent-feeling use of a mark, so it is exactly where the rules are enforced most predictably.

What the domain rules look like in outline

The consistent theme of CREA’s trademark rules, as of mid-2026: the marks must be used in ways tied to your identity as a member, and not in ways that make the mark part of a generic or geographic brand. A domain that couples your own name with the REALTOR® mark sits in the sanctioned pattern; a domain that couples the mark with a city, a property type, or a slogan reads as claiming the mark for a business brand — the classic violation. MLS® in a domain has a second failure mode: implying your website is the MLS or an official portal, which layers misleading-advertising exposure on top of the trademark problem. The specific conditions are policy that CREA maintains and updates, so treat the current trademark manual — not habit, not what another agent’s domain does — as the authority before registering.

The enforcement reality

These marks are defended: protecting them is part of what boards and CREA owe their membership, and complaints are easy for competitors to file. Enforcement typically lands as a demand to stop using the domain — after you have bought it, ranked it, and printed it on everything. The timing is what makes the mistake expensive: a trademark problem discovered at registration costs fifteen dollars and an afternoon, while the same problem discovered two years in costs the SEO equity, the signage, and the email addresses every past client has saved. Unlike most branding mistakes, this one cannot be settled by adjusting a logo; the asset itself is the violation. Meanwhile your registered name and brokerage identification obligations exist independently of the domain question — a compliant domain does not replace the identity rules that govern the site itself.

The better play: a brand you own outright

The agents with the strongest digital brands almost never carry protected marks in their domains — they own their name or an area-plus-niche phrase outright, with no policy dependency and no risk the asset gets recalled. Your name travels with you through brokerage changes; a place brand compounds as your local content deepens. Whether that lives on one domain or several is its own decision, weighed in agent subdomains vs separate domains, and what should sit on the domain is covered in what makes a good realtor website. The credential belongs on the site — the REALTOR® mark used properly in your identification, your board and brokerage stated plainly. The domain is the one place where borrowing someone else’s mark buys you risk and nothing else.
