# Occasionally I see more than one Registrar IANA ID appear in one single domain name WHOIS record. Sometimes the IANA ID looks irregular or even missing. What should I do about it?

Please report your case immediately to [support@whoisxmlapi.com](mailto:support@whoisxmlapi.com) and let us investigate. From time to time, it is caused by either 1) WHOIS parsing issues or 2) special domain transactions that we may have to escalate to relevant TLD operators or ICANN. If it is a parsing error, this can be fixed expeditiously.
