For a general business inquiry, start with NOV’s official Contact Us form or call the Houston headquarters at 346-223-3000. Because NOV operates many specialized business units, callers should know the product, equipment type, business unit, facility, project, or purchase order involved before contacting the company. Supplying the equipment name, serial number, operating location, company name, project information, and an existing NOV representative’s name can significantly improve routing.
For urgent Rig Technologies technical support, use 713-395-5000, which NOV publishes as a 24/7 U.S. technical-support contact. Investor questions should go to 713-375-3826, while governance or ethics concerns can use 1-800-676-4380. Routine product and service matters are usually best handled by the specific business unit or regional NOV facility rather than the corporate executive office.
If an existing customer has an open purchase order, service contract, warranty case, field-service request, or equipment repair, the fastest route is normally the named account manager, service center, or product-support contact on the commercial documentation. NOV is primarily a business-to-business industrial supplier, so it does not use the same centralized call-center structure as a consumer retailer.

Governance complaints by mail can be sent to
Attn: VP Internal Audit
NOV Inc.
10353 Richmond Avenue
Houston, TX 77042
This address is specifically listed with NOV’s Governance Hotline procedures.
Complaints involving equipment performance, service quality, spare parts, commercial support, contract administration, billing, workplace ethics, investor matters, safety, environmental issues, or corporate conduct should be documented carefully. Before escalating, gather the equipment or product name, serial number, project or site location, purchase order, invoice, service record, prior correspondence, employee or representative names, and a clear explanation of the requested resolution.
Begin with the NOV representative or business unit responsible for the product or service. General inquiries can be submitted through NOV’s official Contact Us system, which routes requests according to business unit, brand, equipment, country, and topic. Give a complete description of the issue and provide relevant equipment, location, customer, and contact information so the inquiry can be routed efficiently.
If the problem involves technical equipment, contact the correct product-support or regional service team rather than relying on the corporate office. Rig Technologies customers can use 713-395-5000 for 24/7 technical assistance. Billing, warranty, spare-parts, repair, field-service, or contract complaints should go to the department named on the invoice, purchase order, service agreement, or equipment documentation.
If the first representative cannot resolve the matter, request review by the service manager, business-unit manager, sales manager, project manager, regional manager, or other appropriate management contact. Provide a concise written timeline of the problem, prior troubleshooting, costs or delays incurred, and the outcome requested. Keeping technical evidence, service reports, photographs, purchase orders, and written commitments together can make management review more effective.
Submit the matter through NOV’s official Contact Us process or document the complaint by email with the responsible commercial team. For corporate-governance, accounting, compliance, or conduct concerns, NOV provides a Governance Hotline at 1-800-676-4380 and email at risk.mitigation@nov.com. Complaints through this process can be made confidentially and anonymously where allowed by law.
Serious unresolved corporate matters can be escalated in writing to NOV Inc., 10353 Richmond Avenue, Houston, TX 77042. Include your organization name, contact details, affected NOV product or business unit, relevant contracts or purchase orders, earlier case information, and a chronological explanation of the dispute. Send copies rather than original documents and retain delivery records.
Compliance, governance, accounting, internal-control, auditing, and similar concerns should use NOV’s Governance Hotline or Risk Mitigation team. Investor matters should be directed to Investor Relations, while cybersecurity or data-security questions can use the company’s Trust Center. Using the specialized channel is important because NOV’s corporate operations span many legally and technically distinct business units.
The appropriate regulator depends on the nature of the complaint. Workplace-safety issues may involve OSHA or an equivalent local regulator, environmental concerns may involve the EPA or state environmental authorities, securities-reporting matters can involve the SEC, and export-control or anti-corruption concerns may fall under other federal agencies. Commercial customers should choose the regulator that actually has jurisdiction over the disputed activity rather than filing a generic complaint.
NOV primarily serves commercial and industrial customers, so standard consumer-protection procedures may not apply to most disputes. Payment issues may instead be governed by purchase orders, supply contracts, credit terms, warranties, insurance arrangements, or commercial law. Smaller purchasers should review applicable state consumer-protection options only if the transaction legally qualifies as a consumer transaction.
If contractual escalation fails, review the governing contract for dispute-resolution requirements, choice of law, venue, arbitration, mediation, warranty limitations, and notice provisions. Commercial disputes involving major industrial equipment can involve substantial technical and financial issues, so parties may wish to consult qualified legal counsel before beginning arbitration or litigation. Preserve all purchase orders, service reports, invoices, warranty records, technical evidence, and NOV correspondence.
