WEID notation: weid:1-8-1-6-1-9-2
DER encoding: 06:0F:2B:06:01:04:01:82:A5:31:08:01:08:01:06:01:09


Recommendations for WEID notation (as of Spec Change 9):

  • In Spec Change 9 (08 March 2022), an alternative syntax of WEIDs is defined. This alternative syntax replaces the checksum with a wildcard in form of a question mark symbol, for example, weid:root:2-RR-? instead of weid:root:2-RR-2. One useful scenario can be the documentation of incomplete/template WEIDs. Another usage is converters (like our online converter) which can help you replace the wildcard with the correct checksum.
