How long is an Inquiry Identification Number for an Underground Service Alert (USA) valid?

An Inquiry Identification Number for an Underground Service Alert (USA) is valid for a duration of 28 days. This time frame is designed to ensure that utility companies have a clear period within which they can respond to notifications regarding excavations and potential digging activities that could affect underground utilities. The 28-day validity helps to balance the need for timely communication about potential hazards while ensuring that all necessary work and safety precautions can be organized efficiently. Having an established period for the validity of these inquiry numbers helps streamline the communication process among stakeholders involved in underground construction and maintenance, reducing the likelihood of accidents and ensuring compliance with safety regulations.
