Addresses in the Dominican Republic pair a sector (neighborhood) with a 5-digit INPOSDOM postal code that most people never use, so checkout forms tend to drop one or both. Here is the correct order, a real example, the postal code rules, and the mistakes that cause failed deliveries.
A Dominican label runs recipient, the street and number with the sector, then the 5-digit postal code, then the city or municipality, then the country. The sector (barrio or ensanche) is the field couriers rely on most.

When present the code speeds sorting, but the sector name is what carriers actually navigate by.
Format: 5 digits, no spaces or letters, for example 11903. The first digit denotes the postal region.
Validation regex: ^\d{5}$
Watch for: a missing code, or a code borrowed from a different sector. Since the code is optional in daily use, forms often leave it blank or carry a stale value from autofill.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Dominican addresses hinge on the sector, a neighborhood such as Alma Rosa, Naco or Gazcue. Couriers navigate by sector and street rather than by postal code, so an address without a sector is hard to deliver even when the code is present.
INPOSDOM codes cover the whole country, but locals seldom use them. A form that hard-requires a code pushes customers to invent one, so validate it when supplied but let the sector and city carry the address.
House numbers follow the street with # or No., for example Calle Primera No. 12. Some streets are numbered or lettered (Calle 3, Calle A), so keep the exact designation to avoid landing on the wrong block.
Greater Santo Domingo splits into the Distrito Nacional and the municipalities of Santo Domingo Este, Norte and Oeste. They carry different postal codes, so treating them as one city misroutes parcels between them.
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 Instituto Postal Dominicano, the national postal operator and the source of the 5-digit código postal. It routes by region code, city and sector.
Domestic cargo and courier networks widely used for parcels within the Dominican Republic. They deliver to a branch or to a sector-and-street address rather than a postal code.
International carriers for inbound shipments. Include the country line and a full sector; they surcharge address corrections when a parcel cannot be placed by sector and street.
