According to federal law, what must be checked before making solicitation calls?

The correct answer is the National Do Not Call Registry, which is crucial for compliance with federal law regarding solicitation calls. This registry was established to give consumers control over the telemarketing calls they receive. Prior to making solicitation calls, real estate professionals must consult the registry to ensure they do not contact individuals who have opted out of receiving such calls.

By checking this registry, sellers can avoid potential fines and legal issues that arise from violating the preferences of consumers who wish to limit unsolicited calls. It plays a vital role in maintaining ethical standards and respecting consumer rights in telemarketing efforts.

Other options, while related to real estate processes or regulations, do not directly address the specific requirement under federal law for solicitation calls. Local zoning laws pertain to land use and property development, while state real estate guidelines may cover various aspects of real estate practice but do not specifically address telemarketing regulations. Property ownership records are important for verifying property-related information but are not relevant to the act of making solicitation calls.
