Thank you to all that responded.
I had, before asking the initial question, consulted various lists.
As a matter of interest, what are the stations associated with the
many missing numbers?

In the spreadsheet, which may be wrong anyway, the missing ones seem
to be

0596 between Harlesden and Harrow and Wealdstone in the bit where it's
alphabetical

0790 - 0841 between North Greenwich and the DLR stations

0843 - 0846 (what is 0847 Cheslyn Hay?)

0848, 0849, 0853, 0863, 0868 - 0878, 0880, 0881, 0885, 0889, 0892,
0896 in the DLR-looking series of stations

0899 - 0927 and 0929 - 0939 where they show Greenwich and Lewisham

Are there spare codes for DLR stations not open yet?
