Keep a private address card for repeated forms

A private reference card saves retyping and helps you notice when an address form has placed information in the wrong field.

1. Write your current address as separate parts: recipient, building or apartment, street, locality, postal code and country where relevant. Follow the destination's actual addressing format.
2. Keep any delivery directions separate from the address itself. Do not put entry codes or other access secrets into a reusable address block.
3. When completing a form, match each part to its labelled field, then inspect the assembled address in the confirmation screen. Check apartment details and postal code especially carefully.

Store the card privately and update it after moving. Copying is only the first pass: a form can rearrange or shorten text, so read the final address before submitting it.
