Shipping Zone Calculator

About this calculator

A zone is a courier's own grouping of destinations, and no two couriers group them the same way. One courier's Zone B is a different set of places from another's, and the "national" zone at one is split into two at another. There is no industry standard to look up.

This calculator answers from the zone rules configured on this site for the courier you choose. Where no rule covers the destination, it says so. It does not pick the nearest-looking zone, because a wrong zone selects a rate band and produces a price that looks entirely reasonable and is wrong.

How to use this calculator

1. Choose the courier. Zones belong to couriers, so this cannot be answered without one.
2. Enter as much of the destination as you know. A PIN code is the most precise; a state is enough for most zone rules.
3. Add the origin city and state if your courier prices same-city or same-state deliveries differently.
4. Read the zone, and whether it counts as remote.

The formula

Rules are matched most specific first, so a rule naming one PIN code beats a rule naming the state that contains it:

PIN code        an exact PIN match
PIN range       a range of PIN codes
city            an exact city match
same city       origin and destination in the same city
state           an exact state match
same state      origin and destination in the same state
country         an exact country match

Where nothing matches, the result is that nothing matched, together with the courier it was checked against. That is a configuration gap, not a calculation failure.

Worked example

A courier with these rules, and a parcel to Bengaluru 560001 from Mumbai:

Rule: state = Karnataka          -> Zone C
Rule: PIN range 560000-560999    -> Zone B   <- more specific, wins

The answer is Zone B. The state rule would also have matched, but the PIN range is the more specific of the two and the more specific rule always wins.

Notes and limits

• This site does not ship a PIN code database. A list of that size is stale within weeks, and it is the courier's own zone definition that sets the price - not a general idea of which places are near which.
• Remote or out-of-delivery-area locations normally carry a surcharge separate from the zone rate. Where a zone is marked remote here, the calculator says so.
• Serviceability is a different question from zone. A PIN code can be in a zone and still not be served, or served only by surface.
• Couriers revise their zone maps. Where an answer disagrees with an invoice, the mapping here probably needs updating.

What this calculation assumes

• Zones are the chosen courier's own definitions, as configured on this site.
• The most specific matching rule wins; a PIN rule beats a state rule.
• A destination that matches no rule is reported as unmatched rather than assigned a zone.
