You can change the originally requested release date for any processed (accessioned) GenBank or SRA submissions that are not yet public (unreleased).

The process of requesting a new release date depends on your data: 

• GenBank data
• Sequence Read Archive (SRA) records

GenBank Data

For GenBank data that are not a part of the SRA/BioProject/BioSample release set:

• For submissions made in the Genome component of the Submission Portal, email genomes@ncbi.nlm.nih.gov.
• For the following submission types, email gb-admin@ncbi.nlm.nih.gov:
  • Submissions made in Submission Portal GenBank  
  • Submission made in the TSA (transcriptome) component of the Submission Portal.
  • Targeted Locus Study (TLS) submissions

Sequence Read Archive (SRA) records

For Sequence Read Archive (SRA) records, change the release date using the My SRA Data page in NCBI Submission Portal:

1.  Access the My SRA Data page using the My SRA data link on the NCBI Submission Portal home page. On the My SRA Data page find the BioProject that links to the unreleased SRA data for which you want to change the release date. 
   •  To search use the blue Search panel on the left (check the BioProject and To be released boxes).
2. Click the BioProject accession (PRJNA######) in the Browse table on the right to display the project's page.
3. Click the Edit button located next to the current Release date. From the pop-up window select Release now or provide a new date.  
   • Note that we will release the associated BioProject and BioSample records at the same time as your SRA data.
4. While confirming the change for the SRA data release, you may provide release date information for any assembled GenBank data (e.g., Genome, TSA, TLS) that are associated with the same BioProject. This step is optional and may not be applicable to your submission.

For additional details on changing SRA release date, see SRA documentation.
