Thread: Zip Postal Code validation

Zip Postal Code validation

Hey guys,

Really surprised this has only come up once in the forums (and wasn't answered):

For data reliability/quality, we need to validation the Zip Code field to being 4 digits only (digits only). We don't want people entering text, or mistyping a field. Luckily, it's straightforward for Australia, as it's 4 digits only (no letters).

Does anyone have ideas on this?

Thanks,
Luke
