If you have previously submitted sequences online to any of the IPD components you will have received a unique Submittor ID. This is not the 8-digit Submission ID, which is unique to each submission. The Submittor ID is an 8-digit code comprising 5 numbers, a letter and 2 further numbers.
If you do not have a Submittor ID, please register. You will receive a unique Submittor ID and you will be able to use it for any future IPD submissions. If you forgot your Submittor ID, you can recover it here.
If you want to submit data to the IPD-IMGT/HLA Database, please use the specific online tool.
