Código Universal de Instalação de Gás
The code of the gas supply point for a particular home. You need it when taking out a new gas contract or changing the name on an existing one. The easiest place to find it is on old gas bills.
Where you come across it. Connecting gas, changing supplier or transferring a contract.
Do not confuse it with the CPE: the CPE relates to electricity, the CUIG to gas.
