# Names, addresses and identifiers

Part of Corner cases by Baltor.

Address line parsing, name capitalisation, company suffixes, email and website repair, postal code formats for 246 countries, and validators with check digits.

## What to watch for

- Names typed in capitals lose information a rule cannot fully restore, such as McDonald.
- Postal codes differ by country in length, letters and spacing.
- Card numbers and securities identifiers carry check digits that catch a mistyped digit.
