Idaho Admin. Code r. 31.41.01.101
A local exchange company will not require a deposit or other guarantee as a condition of new or continued residential telephone service based upon residential ownership or location, income level, source of income, employment tenure, nature of occupation, race, creed, sex, age, national origin, marital status, number of dependents, or any other criterion not authorized by these rules. Rules governing deposits will be applied uniformly. If the customer, either residential or small business, selects another company to provide services and arranges to be billed directly by that company rather than through the local exchange company, no deposit may be collected by the local exchange company for the services provided by the other company.
