Which element does NOT need to be included in an advertisement for real estate?

In real estate advertisements, it is crucial to include specific identifying information to ensure transparency and compliance with state regulations. The brokerage firm's name, the registered assumed business name, and the name of the real estate broker are all required to provide clear identification of the parties involved in the transaction. This promotes accountability and allows the public to know who they are dealing with in real estate transactions.

However, including the real estate broker's Department of Licensing (DOL) license number is not a standard requirement in advertisements. While this number is important for verifying a broker's credentials and legitimacy, it is not necessary to disclose it in every advertisement. The focus in advertisements is typically more on the names and branding of the brokerage and the agents rather than specific license details. This is why the DOL license number is the correct choice for what does not need to be included in a real estate advertisement.
