About PostalCodes.pt
A free directory of Portugal's postal codes, searchable by code, address, street, door number or locality and based on imported CTT data.
The data
Postal codes come from CTT — the official source in Portugal — and are refreshed periodically. We cover roughly 192,000 seven-digit codes (CP4-CP3 format), organised by district or island postal area, municipality and locality.
Accuracy & limitations
We aim to mirror the CTT data faithfully. Many postal codes span several streets or a whole locality, so the location shown on the map is approximate (locality- or municipality-level). For critical addresses, always confirm with CTT.
Official confirmation
The postal designation does not always match the locality name and some map positions are approximate. For an important shipment, confirm the address with CTT's official lookup tool.
