Check any regulated hazmat shipping paper and you will find a telephone number marked for emergencies. That number is not a courtesy. It is a regulatory requirement, and mistakes with it are among the most common compliance findings in audits and roadside inspections.
What the rule requires
Under 49 CFR 172.604, a person who offers a hazardous material for transportation must include an emergency response telephone number on the shipping paper, and must make sure the number is monitored at all times while the material is in transportation, including storage incidental to transportation. The number must be that of the shipper or of an agency or organization capable of, and accepting responsibility for, providing the detailed information required. There are limited exceptions, so check the regulation for your situation.
In practice, the phone must be answered by a live person, not voicemail, whenever your material is moving or waiting in transit. That includes nights, weekends and holidays.
Who should answer?
The person monitoring the number must either have comprehensive knowledge of the hazardous material being shipped, including its hazards, how to handle an incident and what to do in an emergency, or have immediate access to a person who does. If a responder calls, the answer must go beyond “I’ll take a message.”
Many shippers cannot staff a knowledgeable person around the clock. Common solutions include:
- Subscribing to a commercial emergency response service, such as CHEMTREC and others, that holds your SDS data and staffs a call center.
- Designating a trained employee rotation backed by SDS files.
- Using a hazmat 3PL that provides an emergency contact for shipments it prepares.
The number should be written next to the description of the hazardous material or at one location on the paper, clearly identified. Many shippers label it “Emergency Contact” so drivers and responders can find it quickly.
Common mistakes
- Using a business-hours switchboard. If nobody answers at 2 a.m., the shipping paper is noncompliant.
- Listing a number for a service you never registered with. A responder who reaches a service with no record of your product cannot help.
- Providing an international number without an on-call response. If shipments cross borders, confirm that the number works for the whole route.
- Failing to update after a vendor change. A disconnected number is a violation waiting to be found.
- Forgetting storage time. The number must stay monitored if a shipment is stored at a terminal or warehouse en route.
Connection to other hazmat documents
The emergency number appears alongside the proper shipping name, UN number, hazard class and packing group. Drivers must also carry emergency response information. Our article on shipping papers and the Emergency Response Guidebook explains how these pieces fit, and our SDS Section 14 guide shows where to find transport data. For other modes, see IATA shipper’s declaration errors.
Why it matters for risk and penalties
Missing or incorrect emergency contact information can be cited as a shipping paper violation and can delay responders in a real incident. Review the common violations and know when to file an incident report.

Frequently asked questions
Can the emergency number be my cell phone?
Yes, if it is monitored at all times while the material is in transportation and the person answering has the required knowledge or immediate access to someone who does. Many shippers prefer a dedicated service for reliability.
Do I need an emergency number for limited quantities?
Many limited quantity shipments are exempt from full shipping paper requirements, which can remove the need for the number. Verify the rules for your specific shipment and mode.
Is CHEMTREC required?
No. The regulation does not name a specific provider. It requires a compliant, monitored number, and a third-party service is one option.
