ISO 9001 Registrars

2 December 2020

Contrary to what many people believe, ISO 9001 certification is not granted by ISO but performed by an independent third party referred to as 'certification body' or 'ISO 9001 registrar'. Choosing the right registrar for your organization is vital. No, it's not just their impact on your budget and the status of your certification. The main concern is how they can affect the ongoing success of your quality management system.

We'll explain what you need to know about ISO 9001 registrars and how to choose one that's right for your company.

ISO 9001 Registrars

Registrar Basics

Given their importance to the success of your ISO 9001 certification and the long-term sustainability of your quality management system, it's important for you to be familiar with some basic facts about ISO 9001 registrars.

What Is an ISO 9001 Registrar?

A registrar is an independent certification body that audits an organization for compliance with ISO 9001 and issues the certificate of conformity. Registrars are private companies that operate in accordance with their accreditation regulations.

What Does a Registrar Do?

Registrars have one or more of their auditors perform compliance audits to assess the organization's conformity with ISO 9001:2015 requirements. These audits are similar to internal audits and include a review of documents and records, observation of work processes, and interviews of management and staff. If conformity with the standard can be established, the registrar issues the ISO 9001 certification.


ISO 9001 registrars must follow extensive regulations stipulated by their accreditation board. Registrars may be accredited to one or more accreditation schemes. In the case of multiple accreditations, clients may choose their preferred accreditation mark to be displayed on their certificate.

How Long Is an ISO 9001 Certification Valid?

Certificates are generally valid for 3 years. After that, the certification can be renewed upon successful completion of a re-certification audit.

What Are Stage 1, Stage 2, and Surveillance Audits?

The initial certification audit is conducted in two phases. The first, the so-called Stage 1 Audit, is essentially a readiness review that comprises an assessment of your ISO 9001 documentation; some registrars add a pre-certification assessment of your operations (which essentially duplicates the next stage). After successful completion, your registrar conducts the Stage 2 Audit – the actual audit of your operations – to evaluate your quality management system for effectiveness and compliance with ISO 9001 requirements.

To maintain your certification it's necessary for your registrar to periodically conduct Surveillance Audits. These are typically scheduled every six to twelve months during the 3-year certification period. They are smaller in scope than the initial certification audit and typically only last about a third as long.

Nowadays Stage 1, Stage 2, and Surveillance Audits can be conducted remotely. Remote audits (also called 'virtual audits') provide similar benefits to on-site audits but are less expensive (there are no associated travel expenses).

Can I Change my Registrar?

It's common to hire a registrar for the entire 3-year registration period. However, you can transfer your certificate to another registrar during the this time and you can renew it with a registrar of your choice.

Creating a list of ISO 9001 registrars and selecting the best candidate

How to Choose the Right Registrar

Not every registrar is a candidate for your organization. It's vital to choose the right registrar for your business as they can play a significant role in the ongoing success of your quality management system. You might be tempted to just look at cost, but other factors should also be considered. Remember, your registrar could support your ISO system and foster improvements and best practices. A registrar that doesn't fit your circumstances could achieve the opposite.

Start your selection process with an ISO 9001 registrar directory or simply search the web for, let's say, 'USA based ISO 9001 registrars'. A better place to start, though, is our partner network of some of the best registrars worldwide. Once you have narrowed down the list of registrar candidates, you may want to interview them by phone, video chat or email.


Costs for certification can vary widely. To a certain extent, the size of your organization determines the cost of the audit, but there are more factors that affect your overall cost.

Registrars base the number of auditor days on your employee count per IAF MD5:2019 regulations, then adjust that baseline to account for the complexity of your operations, the number of shifts, unusual operating hours, and the number of separate facilities. The cost per auditor day varies by registrar.

Additional cost components are travel expenses, the registrar's administrative fees and the accreditation fees for your registration. To reduce your costs, consider the following options:

Avoid travel expenses by requesting a remote audit.

Request a sampling plan if you have more than one physical location.

Skip the optional pre-certification assessment (if you feel the need for one, you'll get better value from our internal audit service).

The quotes you'll receive from our partner registrars are typically all-inclusive and cover the complete 3-year registration cycle, allowing for easy comparison of the candidates on your list of ISO 9001 registrars.

Other Factors

When selecting your registrar, cost will likely be an important factor. However, there are other factors that should be taken into account as they will not only affect the overall time and expenses related to your ISO 9001 certification but also the quality and long-term success of your quality management system.

Accreditation: it's not only important that your registrar is accredited by a national accreditation body but also that the accreditation is popular in your market(s) and accepted by your customers.

Reputation: since the registrar's logo will be part of your certification mark, it's worthwhile to consider the registrar's reputation in your market(s).

Auditors: the experience and attitude of your auditors will have a big impact on your quality management system. An auditor who is easy to talk to and work with, who willingly shares their experience to help you address nonconformities, and who contributes with ideas and best practices, can add tremendous value.

Service: customer service and your point of contact, as well as online systems (for example, to manage nonconformities) should be considered.

Rules: don't forget to ask about rules governing the correction of nonconformities and changes of your auditors (continuity is usually a good thing but you should be able to request a different auditor if you desire).

When to Select Your Registrar

You won't be rushed into making a choice.

You have a higher chance of getting certified in your desired time frame.

You have time to develop a working relationship with your auditors – which could prove useful during the certification audit.

You can ask your auditors questions regarding the ISO 9001 implementation (it might be beneficial to consider the auditor's view.)
