Forgot Your AAAS Number?

All AAAS members and institutional site license subscribers to Science publications receive an eight-digit AAAS number. This number is required to activate your account and should be referenced in all correspondence.

Your AAAS number has 8 digits. You can find it in four places:

  1. If you are a member, it is printed on your membership card.
  2. If you are an institutional subscriber, it is included on your most recent renewal notice or invoice.
  3. If you receive print issues of Science, it is printed on your Science mailing label on the first line. Use only the first 8 digits.
  4. It is printed in your confirmation letter or confirmation e-mail for your online individual or institutional subscription.
