Brentwood is the first station in Essex on that line, as I recall.

Within the current administrative county of Essex, yes.

There have only ever been administrative boundaries.

There are postal boundaries too.

Ah true, and there are telephone codes,

Which rarely have published boundaries.

but they are there purely for operational convenience of service
providers and also change. *They are based on things like the number of
delivery points and capacity of exchanges.

And whose relevance to this conversation is a little obscure.

Town Hall, 128-142 High Road, Ilford, Essex, IG1 1DD

Yes, but it's still the address of the London Borough of Redbridge.

Which is in Essex.

It may have been in a previous "administrative county of Essex", but
that never had any more significance than the current one.

It also isn't really the reason why "Essex" is/was in the postal
address. The Post Office/Royal Mail has its own system for
classifying addresses which are based on its operations and not on
past or present administrative boundaries.
