How do I remove all letters until the first digit with sed?

I have the following lines:

XYZ2342
ABCD1323
KIL9824

And I would like to remove all letters at the beginning, so I would get for the above example:

2342
1323
9824

I have tried this:

echo "ABC12345" |  sed 's/[[:alpha:]]*[[:digit:]]//'
2345

But it also removes the first digit, how can I make sed to delete just the letters (note: they are always ASCII).

I am using FreeBSD sed implementation, in case that is relevant.

sed freebsd

Could you please try following. We need to substitute everything till first occurrence of digits from starting so we need to use [^0-9] regex here, which means from starting substitute everything till first occurrence of digits with NULL here.

echo "ABC12345" | sed 's/^[^0-9]*//'
