It is a guidance standard, not a certifiable one — there is no accredited third-party certification scheme. We help you design, implement and continually improve a complaints-handling process aligned with ISO 10002.

What Is ISO 10002?
ISO 10002 sets out a repeatable cycle for handling complaints — one that narrows in on a resolution and feeds what's learned back into the way the organization operates.
Customer Satisfaction
Receive
Logging the complaint through any channel the customer chooses
Acknowledge
Confirming receipt promptly so the customer feels heard
Assess
Investigating the facts fairly, objectively and without bias
Resolve
Responding with a fair outcome and communicating it clearly
Improve
Feeding findings back into products, service and process
This is a simplified visual aid and does not replace the full ISO 10002 guidelines.
Who Should Use ISO 10002?
ISO 10002 is written to be used by any organization that deals with customers, regardless of size or sector. It is commonly adopted by:
Benefits of Implementing ISO 10002
What a structured complaints-handling process changes in practice.
Higher Customer Retention
A well-handled complaint often rebuilds trust more effectively than a problem-free experience.
Fewer Repeat Complaints
Root-cause findings feed back into products and processes, reducing recurrence.
Consistent Handling
Every complaint follows the same fair, objective process — regardless of who receives it.
Stronger Reputation
Visible, responsive complaint handling shapes how customers describe you to others.
Better Internal Visibility
Leadership gains a clear, evidence-based view of where customers are struggling.
Improved Regulatory Standing
A documented process supports sectors where complaint handling is monitored or audited.
Complaint Handling Principles
ISO 10002 is built on a small set of principles that shape how every complaint should be handled, not just some of them.
Commitment
Leadership actively supports an effective complaints process
Accessibility
Easy to find, use and understand across every channel
Responsiveness
Complaints acknowledged and progressed without delay
Objectivity
Each complaint assessed fairly, equitably and without bias
Confidentiality
Complainant information protected and used only as needed
Customer-Focused Approach
Openness to feedback, including criticism, as a resolution input
Accountability
Clear ownership and reporting for complaint-handling decisions
Continual Improvement
Complaint data routinely used to improve products and process
Summarized for clarity — the full ISO 10002 guidelines set out these principles in more detail.

Sample Certificate of Completion
ISO 10002 is a guidance standard — it does not have a formal, accredited third-party certification scheme the way ISO 9001 or ISO 27001 do. What organizations typically receive is a certificate of completion for a complaints-handling implementation or training engagement. Here's an illustrative example.
Sample certificate of completion shown for illustration purposes only. ISO 10002 has no formal third-party certification scheme — actual completion certificate format may vary by engagement.
A completion certificate generally identifies:
- The engaged organization
- The engagement scope — implementation or training
- Completion date and identification details
- The facilitating advisory provider

ISO 10002 — Frequently Asked Questions
What is ISO 10002?
ISO 10002 is an international standard that provides guidelines for planning, designing, operating, maintaining and improving an effective complaints-handling process, focused on customer satisfaction.
Is ISO 10002 certification available?
No. ISO 10002 is a guidance standard, not a management system standard — there is no accredited third-party certification scheme for it, unlike ISO 9001 or ISO 27001. Organizations implement its guidelines and can complete advisory or training engagements, but no accredited body issues an 'ISO 10002 certificate.'
How is ISO 10002 different from ISO 9001's complaint-related requirements?
ISO 9001 requires organizations to monitor customer satisfaction and handle complaints as part of a broader quality management system. ISO 10002 is a dedicated, detailed set of guidelines focused specifically on how to design and run the complaints-handling process itself.
Does ISO 10002 apply to complaints received through any channel?
Yes. ISO 10002's guidelines are channel-agnostic — they apply whether a complaint arrives by phone, email, chat, social media, in person, or through a formal ticketing system.
What is a complaints register?
A complaints register is a structured record of each complaint received, its assessment, resolution and root cause — a core working document in most ISO 10002-aligned processes.
Can ISO 10002 be combined with other standards?
Yes. ISO 10002 is commonly implemented alongside ISO 9001, ISO 27001 or ISO 31000, feeding complaint and risk data into the same broader management system.
How long does an ISO 10002 implementation take?
Timelines vary based on organization size, number of channels and existing complaint-handling maturity. We can share a realistic estimate after an initial current-state review.
Does ISO Certification Hub issue an ISO 10002 certificate?
We can issue a certificate of completion for our advisory or training engagement. This is not an accredited ISO 10002 certification, since no such accredited scheme exists for this standard.
