Bahrain has no street names in the Western sense. Every address is a building number, a road number, and a block number, and the block number does the routing that a postcode does elsewhere. Here is the correct structure, a real example, the block rules, and the mistakes that strand parcels.
A Bahraini address runs recipient, optional company, the building and road numbers, the town or city, then the block number, then the country. The block number ties the whole address together.

Bahrain Post assigns each town a set of numbered blocks, and the block pins the address to a small area, so a correct block matters more than the building or road text.
Format: A 3-digit block number, occasionally 4 digits, for example 317. It is the block, not a separate ZIP-style code.
Validation regex: ^(?:^|\b)(?:1[0-2]|[1-9])\d{2}(?:$|\b)$
Watch for: a block number dropped from the address, or a made-up 5-digit code copied from a US form. Bahrain routes on the 3 or 4-digit block only.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Bahrain locates every property by three numbers: a building, a road, and a block, written as Building 220, Road 1704, Block 317. There are no named streets to fall back on, so a checkout with only a free-text street line invites incomplete entries.
The block number is what Bahrain Post and couriers sort on. Blocks run in ranges by town, with central Manama in the 300s. Omit the block and there is no reliable way to route the parcel.
Both are numbers and both sit on the same line, so Building 1704, Road 220 instead of Building 220, Road 1704 points to the wrong plot. Label each number so the two are never transposed.
Bahrain never adopted a long postal code. If a form forces a 5-digit ZIP, customers invent one and the fake code travels with the order. Validate the block instead and leave the ZIP field out.
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 national postal operator. It defined the block-based addressing scheme, so the building, road and block numbers are exactly what its network sorts on.
The dominant regional courier for Gulf ecommerce. It expects the full building, road and block, and uses the block for last-mile assignment in Bahrain.
International carriers for inbound shipments. Include the country line and a phone number; they surcharge address corrections when the block is missing or wrong.
