This article explains why there's a character limit for address lines.

Shipping providers often have character limits for address labels. If an address exceeds the limit, important information might be cut off, leading to delivery issues.

Gelato has over 10 years of experience shipping to over 100 countries. Based on this experience, the character limits shouldn't pose issues, even for long addresses. You can shorten words like "Avenue" or "Building" to help keep your address within the limits.
