You could put the IDs in a email message and send to the GenBank e-mail
server at:  retrieve at ncbi.nlm.nih.gov

(I assume by IDs, you mean the locus names)

Send a message with the word 'help' first, to get the Help documentation.

But essentially all you should need to do is send something that looks like:

datalib genbank
humgrp78 [loc]
atluglgc [loc]

The '[loc]' is not essential; it limits the search to the locus field so
that some records which may happen to have the locus name referred to in
other parts of the record would be excluded.

You should probably do this in batches of 50-100 query terms so the return
e-mail message is of reasonable size.
