Intermediate CAs issued by this root
The CCADB lists 4 intermediate CA certificates signed directly by AC RAIZ FNMT-RCM SERVIDORES SEGUROS: 4 currently valid, 0 expired and 0 revoked (revoked includes those whose parent was revoked).
Showing 4 of 4: valid certificates first, newest first. Each name links to its crt.sh entry by SHA-256; an arrow marks a cross-certificate for another root on this site.

Cross-signed versions
No certificate in the CCADB has the same subject and public key as AC RAIZ FNMT-RCM SERVIDORES SEGUROS with a different issuer, so a client has to carry AC RAIZ FNMT-RCM SERVIDORES SEGUROS itself in its root store to trust it.
CRL and OCSP addresses
In the root certificate
AC RAIZ FNMT-RCM SERVIDORES SEGUROS itself contains no CRL Distribution Points and no OCSP (Authority Information Access) extension. That is normal for a root: clients trust it directly and do not check its own revocation status.

What happens when it expires
AC RAIZ FNMT-RCM SERVIDORES SEGUROS is valid until 2043-12-20, about 17.1 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.
Check whether your device trusts it
Each platform keeps its own root store. The commands below look up AC RAIZ FNMT-RCM SERVIDORES SEGUROS by common name (AC RAIZ FNMT-RCM SERVIDORES SEGUROS) or fingerprint. The store status in each heading comes from the CCADB snapshot; your device can differ if it is out of date or managed by an administrator.
macOS (Apple store: Not included)
Search the system roots keychain by common name. -Z prints the SHA-256 hash, which must match the fingerprint on the last line.
security find-certificate -a -c "AC RAIZ FNMT-RCM SERVIDORES SEGUROS" -Z \
/System/Library/Keychains/SystemRootCertificates.keychain | grep "SHA-256"
# SHA-256 hash: 554153B13D2CF9DDB753BFBE1A4E0AE08D0AA4187058FE60A2B862B2E4B87BCB
Windows (Microsoft store: Included · Trusted for TLS)
Windows identifies roots by SHA-1 thumbprint. It installs third-party roots on demand through Automatic Root Certificates Update, so "not found" can also mean the root has not been needed yet; certutil -generateSSTFromWU roots.sst downloads Microsoft's full list.

Linux (ca-certificates follows Mozilla: Included · Trusted for TLS)
Debian, Ubuntu, Fedora and RHEL build their ca-certificates package from Mozilla's root store. Use trust list on p11-kit systems, or search the PEM bundle on Debian and Ubuntu.
# Fedora / RHEL / Arch (p11-kit)
trust list --filter=ca-anchors | grep -iF -A2 "AC RAIZ FNMT-RCM SERVIDORES SEGUROS"
# Debian / Ubuntu (ca-certificates)
openssl crl2pkcs7 -nocrl -certfile /etc/ssl/certs/ca-certificates.crt \
| openssl pkcs7 -print_certs -noout | grep -iF "AC RAIZ FNMT-RCM SERVIDORES SEGUROS"
Java
Java ships its own cacerts keystore; JDK 9 and later accept -cacerts and the default store password is changeit. Search for the SHA-256 fingerprint in colon form.
keytool -list -cacerts -storepass changeit | grep -i "55:41:53:B1:3D:2C:F9:DD:B7:53:BF:BE:1A:4E:0A:E0:8D:0A:A4:18:70:58:FE:60:A2:B8:62:B2:E4:B8:7B:CB"
Android
Android's system store is maintained by Google separately from the four CCADB stores above. Open Settings → Security & privacy → More security settings → Encryption & credentials → Trusted credentials → System (menu names vary by vendor and version) and look for FNMT-RCM → AC RAIZ FNMT-RCM SERVIDORES SEGUROS.
