About Postal Code 21657 in BATU BARA, SUMATERA UTARA

Postal Code 21657 for BATU BARA, SUMATERA UTARA is part of the Indonesia postal code system, which uses a numeric code of 5 digits (e.g. 40135). Addresses here are organised as Provinsi → Kabupaten / Kota → Kecamatan → Desa / Kelurahan.

Administratively it is recorded in SEI SUKA, SUMATERA UTARA within Indonesia. Postal codes are assigned by delivery route rather than by administrative boundary, so a single code can cover more than one locality and a locality can fall under several codes.

This database holds 16 building or address records linked to this code. Each entry below is a reference from the imported source dataset rather than a verified postal address, listed so the code can be placed in context.

Couriers, e-commerce checkout forms and address autocomplete tools all rely on the postal code to route mail and to check that a stated address matches the code. Because a postal code identifies a delivery area rather than a single building, two addresses that share the same code can still be some distance apart.

Always write Indonesia Postal Code in full when completing a form, including any leading zero. Enter a 5-digit Indonesian postal code (kode pos). Data source: BPS Kode Pos Indonesia (edwin/database-kodepos-seluruh-indonesia). This is a reference snapshot, not a live government feed, so confirm the code with the sender, carrier or postal authority before relying on it.
