The ABI is urging IFAs to sign up for its Year 2000 database with only an estimated third of intermediaries joining since the May launch.
Two thousand IFAs and 133 insurers have provided information on their state of millennium compliance.
ABI electronic commerce manager John Kemble says: "All the indications are that the industry still has some way to go before it can claim to be totally Year 2000 compliant. The database is the only way to avoid the massive duplication in effort involved where companies check compliance of trading partners individually."
The ABI accepts that not all intermediaries may sign up but still believes that the database will be useful in cutting down on duplication.
