# How to check a dietitian's credential

Credentials and registers are public. Check before you book: CDR in the US, HCPC in the UK, provincial colleges in Canada, Dietitians Australia in Australia and CORU in Ireland.

Credentials are public. Each body below lets you check a practitioner in minutes. Do it before you book, and again if a lot of time passes.

## United States

In the US, whether the "dietitian" title is regulated depends on the state: each state sets its own licence rules, and they differ. The Registered Dietitian (RD) and Registered Dietitian Nutritionist (RDN) titles are the Commission on Dietetic Registration credential. Its online credential verification system asks for the CDR registration number and the practitioner's country or state of residence, then shows the credentials on file.

Many US states also require a separate state licence to practise as a dietitian. Your state health or professional regulation department holds that register.

## United Kingdom

Dietitians in the UK register with the Health and Care Professions Council (HCPC). The HCPC Check the Register tool confirms a professional is on the register and shows their registration status and any conditions. [HCPC, accessed 2026-11-13.]

## Canada

Dietitians of Canada runs a member directory where you can search by name, city, province and area of expertise. Registration itself sits with provincial regulatory colleges, so confirm the college for the province where the dietitian practises. [Dietitians of Canada, accessed 2026-11-13.]

## Australia

Accredited Practising Dietitian (APD) is a professional credential, not government registration, run by Dietitians Australia. Australia has no statutory register for dietitians. Their Find a Dietitian tool lists APDs and lets you check a practitioner's credentials. The site notes it does not review or verify the information in the directory; the professionals listed provide it. [Dietitians Australia, accessed 2026-11-13.]

## Ireland

Dietitians in Ireland register with CORU, the Dietitians Registration Board. The CORU register on coru.ie lets you check a dietitian's registration. [CORU, accessed 2026-11-13.]

## What a clean check proves, and what it does not

A current registration proves the person met the training, supervised practice and exam requirements, and keeps them current. It does not prove availability, price, specialty fit or good fit for you. For those, read the practice's own website, ask about their experience with your goal, and book a consultation.

## Questions

### Where do I check a US dietitian?

The Commission on Dietetic Registration runs an online credential verification system at secure.eatright.org. Enter the registration number and the practitioner's country or state.

### Does an RD title guarantee good care?

No. Registration proves the credential and its upkeep, not the quality of care. It does prove the person met the education, practice and exam requirements.
