Polysomnography

California law requires all licensees/registrants to report each and every change of address/email within 30 days after each change.

You may submit a change of address/email through the Breeze system.

If the new address is a post office box, the licensee/registrant is required by law to provide the Board with a separate street address which will be kept confidential and not publicly disclosed. The street address of a private mailbox service may not be used as a confidential street address. Even if a licensee/registrant provides a street address as their address of record, they may provide a second street address that will remain confidential.

Note: California law requires the Board to provide, upon written or verbal request, the address of record of any licensee or registrant. The address of record will be released to any individual or entity who inquires and is also available to the public on the Board's website. Each licensee/registrant should carefully consider the address of record provided to the Board, and may wish to use an office, employer's address, or a post office box as the address of record.

The Board uses the address of record to mail all licenses, renewal notices, and all other official correspondence, therefore, the licensee/registrant is responsible for all communications sent to their address of record.

California law requires each licensee/registrant to report name changes to the Board within 30 days of the name change.
