If you suspect, or want to check to see if you have multiple NCBI accounts, write to us at and include the following in your message: NCBI username, eRA Commons username (if applicable), and any email addresses that may be associated with your account(s). Also let us know if you have previously used an NCBI account for submitting sequences or other molecular data.

If multiple NCBI accounts do exist, the NCBI customer support can merge them into a single account.
