Structured vs. unstructured address

Starting from November 23, 2025, the European Payments Council mandates that SEPA participants use structured addresses instead of unstructured addressed.

The key differences between unstructured addresses and structured addresses are the following.

Unstructured address

An unstructured address contains a country (usually in the form of an ISO-3166 country code) and up to two address lines.

In Mambu Payments, it means using the country, and line_1 / line_2 properties. Address lines can contain anything relevant that identifies an address, hence the name unstructured.

Structured address

A structured address must include a country and city as well as split street name and building number.

In Mambu Payments, it means filling the country and city properties as well as optionally filling other properties like building_number, street_name, region_state, and postal_code, except the line_1 and line_2 unstructured properties.
