52.204-12 - What does "throughout life of contract" mean?

[mtclymer]

Does anyone have experience on what "throughout the life of contract" means in 52.204-12? (see pasted clause below, I have bolded in blue the reference)

I have checked definitions, prescription etc. The issue is this: When can I retire a DUNS number?

The guidance on CAGE codes is clear, but because a contract may be awarded by DUNS and not CAGE code, I can't assume the same guidance for retirement of a CAGE code applies to a DUNS. A CAGE code has to remain active in SAM until final payment and active in the DLIS Master CAGE code listing until parts are dispositioned, FCL is closed and all contracts closed out.

For contracts that pay through DFAS, it's very clear the DUNS has to stay active through final payment as those contracts will have a CAGE code and EFT information in SAM so we can be paid. What about contracts with a DUNS that don't pay through DFAS?

Is "throughout the life of the contract" the performance period or until final payment/release?

Many thanks in advance for your thoughts and inputs.
