Where This Clue Appears
The CodyCross clue “ISBN __; unique identifiers for commercial books” is answered by NUMBERS, a 7-letter entry in the The 80s world, group 799, puzzle 4. The full puzzle page lists every other clue in that same grid, which is usually what you want if more than one row is blocking you.
Check the letter count before you commit. CodyCross fixes the length of every row before you type, and the game reuses the same clue wording in different worlds with entirely different solutions — so a clue that looks identical to one you have already solved may want a different word here. If your grid shows a different number of squares than the 7 above, you are almost certainly on the same clue from another world.
You can browse the whole game from the world index — 108 worlds, 2,144 groups and 10,716 puzzles — or check the separate daily crossword archive.
