Panama has no national postal code for street addresses. Mail is routed by corregimiento (township), city and province, and much of it goes to an apartado (PO box) rather than a home. Here is the correct structure, a real example, and the mistakes that cause failed deliveries.
A Panama label runs recipient, the street or avenue with the building and floor, the corregimiento, then the city and province, then the country. There is no postal code line for street delivery; PO box mail uses an apartado number instead.

Correos de Panamá routes by corregimiento, city and province, and many residents and businesses receive mail through an apartado (PO box). The apartado carries a zone-based number, but there is no code for street delivery.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Unlike most countries, Panama has no national postal code for home addresses. A form that requires a ZIP produces junk data, so make the field optional or omit it and rely on the corregimiento and city.
The corregimiento (township) is the key locality unit, for example Bella Vista or San Francisco in Panama City. It sits between the street and the city and does the work a postal code would do elsewhere.
Home delivery is limited, so a large share of mail goes to an apartado (PO box) written as a zone-based number like 0801-00123. An apartado is a valid destination, not an incomplete address.
For orders from abroad, Panamanians often ship to a casillero (a Miami mailbox forwarded to Panama). The delivery address is then the courier's local hub plus a member code, not the customer's home.
Each of these passes a basic "is this field filled in" check but fails at the carrier, turning into a redelivery, a return, or an address correction fee.

The main international carriers into Panama, including the Colón Free Zone. Include the country line; they charge address-correction fees when a corregimiento or building reference is missing.
