In-checkout validation settings

Use this tab to define what AddressPill checks in checkout.

Address validation (require house number): checks if a street number exists.
Check names (first and last name must differ): catches duplicate names.
Block special characters in address: flags unusual symbols.
Check email typos: catches common domain typos.
Block address with custom regex: blocks patterns you define.
Length limits: restricts max characters for address fields, names, and company.

For many rules, you can choose:

If you are new, start with warnings first, then move to blocking rules after testing.

Most merchants start with require house number because it prevents common delivery failures.

Yes, you can enable only the rules you need and leave others off.

It is safer to start with warnings, validate behavior, and then block critical rules.
