## Cross-signed versions

3 certificate(s) in the CCADB have the same subject and public key as COMODO ECC Certification Authority but a different issuer. A server can send one of them so that clients which trust the issuing root, but not COMODO ECC Certification Authority, can still build a chain.

## What happens when it expires

COMODO ECC Certification Authority is valid until 2038-01-18, about 11.2 years after this data snapshot (2026-11-10). From that day, browsers and operating systems that check trust-anchor expiry stop accepting chains that end at this root, so any certificate that can only chain to it fails validation. Android is a known exception: it does not enforce the expiry date of trust anchors. Root programs can stop trusting it before it expires: Chrome 2026-09-30.
