Public IBCLC Certification Registry

You can find the official Public Registry of IBCLCs below.

To use the registry to verify the credentials of any IBCLC, please search by:

  • IBCLC Credential Number (L-#) (Case sensitive and must be an exact match. Please use a capital “L” and a dash “-” in the “Certification L-#” field, for example: L-12345.)
  • Name (we recommend searching by full first and last name. It is possible to search by name in primary language, however, not all IBCLCs have this on file with IBLCE.)

Click “Search” to start.

IBLCE’s new, dynamic registry updates within 24 hours of changes being made. This includes current certification expiration dates for IBCLCs who successfully recertify, as well as name updates once approved. Your clients or employers can search for you by your name, to include your name in your primary language if provided, or your Credential Number (L-#).

If you have any questions about IBCLC certification verification, please contact the regional location that serves you. 

You may also confirm that an individual is certified with the most up-to-date information by executing the Certification Verification Form using the IBCLC Credential Number (L-#) and forwarding to the appropriate regional location. We require the use of this Certification Verification Form. External release forms are not accepted, as some forms do not comport with IBLCE policy, inclusive of data privacy.

IBCLCs can also contact their regional location for a letter verifying certified status that can be provided to third parties.

*For candidates in the Americas and Israel region: If you need to send your certification verification form, please do so only via email to iblce@iblce.org.

Important Notes about IBCLC Credential Numbers:

IBCLCs can find their Credential Number (L-#) in their account of IBLCE’s online credential management system. Once you log in, you can find it in the “My Credentials” tab of your account. Learn more about accessing your account here. For those whose certification is lapsed/expired, you will receive a new Credential Number if you become certified again. Your original Credential Number will no longer be valid. Please follow the directions above to learn how to find your Credential Number in your online account.

IBCLC Certification Start and Expiration Dates:

Please note that start dates for new certificants are dependent upon the examination passed. For those who pass the March/April IBCLC examination, the start date is July 1 of that year; for those who pass the September examination, it is January 1 of the next year. IBCLCs are certified for five years.

Expiration dates for IBCLCs are December 31 of the year they are due to recertify, except for those who do not pass the March/April examination: their expiration date will change to June 30 of that year, due to not meeting IBCLC recertification requirements at that time.
