If you have a Google Scholar Profile, ResearcherID, or Scopus Author ID, you may import your publication records from those systems into your ORCID account.
Google Scholar
Some departments may require their faculty members to create a Google Scholar Profile. Although there is no direct integration between Google Scholar and ORCID, you may export your publication records from Google Scholar Profile in BibTeX files and import the BibTeX files into your ORCID.
Sign into your Google Scholar Profile and select the publication records you want to export

Click "EXPORT" and select "BibTeX"

Copy the texts from the browser, paste them in a Notepad, and save it somewhere you can retrieve

Sign into your ORCID, click "Add works", and select "Import BibTeX"

Click "Choose file" and select the saved BibTeX file

Click the save icon to finish the import

Scopus Author ID
The Scopus Author ID is specific to Elsevier and is used in Scopus. The Scopus Author ID automatically assigns a unique identifier to authors with publications indexed in Scopus via an algorithm based on certain criteria. Therefore, it is not uncommon to see multiple Scopus Author IDs being assigned to the same author. In other words, you may have multiple IDs in Scopus if you published your works under different names and affiliations. Scopus provides citation metrics to a list of publications grouped under a Scopus Author ID, thus you can be benefited from having one single Scopus Author ID. Scopus has developed an author feedback wizard to guide users to merge multiple Scopus Author IDs into one profile and edit documents. You may also send a list of your publications from your Scopus Author ID to ORCID.
Sign into your ORCID account. Under the "Works" section, click "+ Add" and "Search & link".

Select and click "Scopus – Elsevier" on the list of databases

Enter your name in the text boxes. If you want to narrow down the search, you may add affiliation. And then Click "Start"

Select your Scopus profile and click "Next"

Select your preferred profile name from the drop-down menu and click "Next"

Review the publication list and indicate which publications are yours. To add other publication to the list, click "Search for missing documents"

Enter your email address to which Scopus will send notification, and then click "Send Author ID"

Click "Send my publication list" to complete the importing
