What each part of a location's code means, how the code styles build codes, and which code to scan, type or read.

In short

A location's Code is unique in its zone and is what its barcode holds. Its Full Location Code puts the warehouse and zone codes in front, such as COL-PR-A-01-B-2, and is unique in your team.

The codes

Each location has a Location Code and a Full Location Code, built on its warehouse's Warehouse Code. Examples are from the Trentside demo's Colwick Distribution Centre.

Code Example Unique in
Warehouse Code COL Your team
Zone code PR Its warehouse
Location Code A-01-B-2 Its zone
Full Location Code COL-PR-A-01-B-2 Your team

You see the first three as Code on the warehouse, zone or location, and the last as Full Location Code. The Warehouse Code is also in delivery numbers, such as INB-COL-000023. A location's label has its Location Code as the barcode, with the Full Location Code in small print under it.

The Full Location Code is always the warehouse, zone and location codes joined by -. A location with no zone has no zone part, such as W1-DOCK-1.

Code styles

Batch Generate builds Location Codes in one of two code styles.

Style Example Built from
Short A1A1 Aisle letters, rack numbers, shelf letters and location numbers, with no separator
Custom A-01-B-2 Each level's Prefix, letters or numbers and Padding, joined by the Separator (- to start)

Colwick's pick faces use Custom with no separator and racks padded to 2 digits: P01A1. Its pallet racking uses Custom with -: A-01-B-2.

The parts of a location code

So what does A1A1 mean? Aisle A, rack 1, shelf A, location 1. The last part of a code, for the location itself, is its Location Segment.

Part In A-01-B-2 In A1A1
Aisle A A
Rack 01 1
Shelf B A
Location, the Location Segment 2 1

Layout rule values

A layout rule gives one level's codes.

Range 1 to 10 1, 2 … 10
Range 1 to 10, Padding 2 01, 02 … 10
Range A to D A, B, C, D

Prefix R with Range 1 to 2 R1, R2
A shelf rule with Applies to 1 Shelves for rack 1 only, in every aisle

In Applies to, name parents by their full code, prefix included: A1, not 1, for aisle prefix A.

Warehouse Codes

Rule Example
1 to 4 capital letters or digits W1, LEI, COL
No hyphen or space W-1 is refused
Lower case becomes capitals w1 is saved as W1
Fixed once a Transaction Number, such as a delivery's, has used it INB-COL-000023 keeps COL
Never used again by another warehouse once numbers carry it Not even after the first warehouse is deleted

Which code to scan or type

You have What Stockist finds
A label's barcode, the Location Code The location in your Working Location's zone, or the only location in your team with that code
A Full Location Code That location, from anywhere

On the Rapid Scanner, scan a location in the zone first, so it becomes your Working Location. When typing a code that more than one zone uses, type the Full Location Code instead.
