Basis Of Presentation And Consolidation [Abstract]
Revenue Recognition	Revenue Recognition We recognize revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery of the product has occurred or a service has been provided, (iii) the price is fixed or determinable and (iv) collectability is reasonably assured. Revenues are earned from our customers primarily through the connection to our local network, digital and commercial television programming, and Internet services (both dial-up and high-speed broadband). Revenues for these services are billed based on set rates for monthly service or based on the amount of time the customer is utilizing our facilities. The revenue for these services is recognized when the service is rendered. Revenues earned from interexchange carriers accessing our network are based on the utilization of our network by these carriers as measured by minutes of use on the network by the individual carriers. Revenues are billed at tariffed access rates for both interstate and intrastate calls. Revenues for these services are recognized based on the period the access is provided. Interstate access rates are established by a nationwide pooling of companies known as the National Exchange Carriers Association (NECA). The Federal Communications Commission (FCC) established NECA in 1983 to develop and administer interstate access service rates, terms and conditions. Revenues are pooled and redistributed on the basis of a company's actual or average costs. New Ulm Telecom's settlements from the pools are based on its actual costs to provide service, while the settlements for NU Telecom subsidiaries – Western Telephone Company, Peoples Telephone Company and Hutchinson Telephone Company (HTC) are based on nationwide average schedules. Access revenues for New Ulm Telecom include an estimate of a cost study each year that is trued-up subsequent to the end of any given year. Our management believes the estimates included in our preliminary cost study are reasonable. We cannot predict the future impact that industry or regulatory changes will have on interstate access revenues. Intrastate access rates are filed with state regulatory commissions in Minnesota and Iowa. We derive revenues from system sales and services through the sale, installation and servicing of communication systems. In accordance with GAAP, these deliverables are accounted for separately. We recognize revenue from customer contracts for sales and installations using the completed-contract method, which recognizes income when the contract is substantially complete. We recognize rental revenues over the rental period.
Cost Of Services (Excluding Depreciation And Amortization)	Cost of Services (excluding depreciation and amortization) Cost of services includes all costs related to delivery of communication services and products. These operating costs include all costs of performing services and providing related products including engineering, network monitoring and transport cost.
Selling, General And Administrative Expenses	Selling, General and Administrative Expenses Selling, general and administrative expenses include direct and indirect selling expenses, customer service, billing and collections, advertising and all other general and administrative costs associated with the operations of the business.
Depreciation And Amortization Expense	Depreciation and Amortization Expense We use the group life method (mass asset accounting) to depreciate the assets of our telephone companies. Telephone plant acquired in a given year is grouped into similar categories and depreciated over the remaining estimated useful life of the group. When an asset is retired, both the asset and the accumulated depreciation associated with that asset are removed from the books. Due to rapid changes in technology, selecting the estimated economic life of telecommunications plant and equipment requires a significant amount of judgment. We periodically review data on expected utilization of new equipment, asset retirement activity and net salvage values to determine adjustments to our depreciation rates. Depreciation expense was $4,535,234 and $5,283,967 for the nine months ended September 30, 2012 and 2011. We amortize our definite-lived intangible assets over their estimated useful lives. Identifiable intangible assets that are subject to amortization are evaluated for impairment.
Income Taxes	Income Taxes The provision for income taxes consists of an amount for taxes currently payable and a provision for tax consequences deferred to future periods. Deferred income taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities, and their respective tax basis. Significant components of our deferred taxes arise from differences (i) in the basis of property, plant and equipment due to the use of accelerated depreciation methods for tax purposes, as well as (ii) in partnership investments and intangible assets due to the difference between book and tax basis. Our effective income tax rate is normally higher than the United States tax rate due to state income taxes and permanent differences. We account for income taxes in accordance with GAAP. As required by GAAP, we recognize the financial statement benefit of tax positions only after determining that the relevant tax authority would more-likely-than-not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. We had no net unrecognized tax benefits at September 30, 2012 that, if recognized, would affect the income tax provision when recorded. We are primarily subject to United States, Minnesota and Iowa income taxes. Tax years subsequent to 2008 remain open to examination by federal and state tax authorities. Our policy is to recognize interest and penalties related to income tax matters as income tax expense. As of September 30, 2012 and December 31, 2011 we had no interest or penalties accrued that were related to income tax matters.
Recent Accounting Developments	Recent Accounting Developments We reviewed all other significant newly issued accounting pronouncements and determined they are either not applicable to our business or that no material effect is expected on our financial position and results of operations or disclosures.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
