How can I know if I am blacklisted in GCC after running away from the UAE?

If your records are clear in other countries, then, yes, you may travel.

In general, the security link between the countries of the Gulf Cooperation Council contributed to the fact that any violator of labor regulations in one of the Gulf countries is considered a violation of the other five countries, and is prohibited from entering the lands of those countries to limit the presence of violators of the regulations and prevent criminals from entering any of the Gulf countries.

However, this does not preclude making sure of that, but in a very large percentage, the matter is settled.
