What can CA mean? When it is before a number?

Most probably, it means approximately, roughly, not exactly.

Here is what Longman ( says about it.

ca. (also ca) British English
a written abbreviation of circa (=about):
dating from ca. 1900

circa preposition
used before a date to show that something happened close to but not exactly on that date:
manuscripts dating from circa 1100

Another option is to try to find other possible meanings at Acronym Finder ( but actually it is quite tough to deduce the meaning without the context.

Any questions?
