Adding an Inventory

Inventories are submitted by BrickLink members on the Add Inventory page. After being submitted, they must be approved by an Inventories Administrator before they become available.
Step 1: Select Item
Enter the item number of the item you want to inventory. Enter the number of entries needed to complete the inventory. You may estimate this number because you can add and remove entries on the next page.
Step 2a: Enter Parts
You will be presented with a list of entries (1 per each unique item in the inventory). The following is a list of all of the fields:
  • Item Type - Enter the Item Type code. The only allowed types here are S (sets), P (parts), B (books), G (gear) and M (minifigures). Instructions are not included in inventories. Minifigure inventories only allow P (parts) to be added.
  • Element ID - Also known as the Part Color Combination Code, If a known number is entered, the Item Number and Color ID data will be filled in automatically.
  • Item No - Enter the Part, Set, Minifigure, Gear or Book number.
  • Color ID - Enter the Color code as seen in the Color Table. Parts and Gear require either a color number or 0 for Not Applicable. For all other item types, leave the field blank.
  • Qty - Enter the quantity of the item that appears in the inventory.
  • My Notes - This field is for you to take notes on this page only. This information is not saved anywhere beyond this page.
  • Type - Choose Regular, Extra, Alternate or Counterpart. Type Explanation
  • Match ID - Identifies a match between Regular item(s) and Alternate item(s). The Match ID must be the same for every item included in the pair or group. In each inventory, the Match ID should start with 1 and increase incrementally by 1 for each new match.

Sometimes basic inventory data for a Set or Gear is already available online. A dialog box will give you the option to use this data as a base for the inventory. Some of the entries will require action before moving to the next step:

  • Red lines - This occurs when the inventory has an Element ID that does not yet appear in the BrickLink catalog. (For example: a new part or new part/color combination.) Enter the Item No. and Color ID if known. If not, delete both the Element ID and Qty data from this entry and add the new item after submitting the inventory.
  • Blue lines - This occurs when an item has an Element ID that matches two or more items in the BrickLink catalog. Click in the Element ID box and then select the correct part or color variation from the resulting drop down menu.

Step 2b: Select Source
At the foot of the page, there is a dropdown menu to select the source you are using. Sources are defined as follows:

  • Set Box/Picture - This source should only be used when set instructions, parts lists, and new or used sets are not available.

    Reliability rating: 1 (least reliable).

  • Description - This source may be used for items like torso assemblies which describe the entire item in the title.

    Reliability rating: 2 (marginally reliable).

  • Used Set - This source may be used for older sets when sealed sets are not available. If instructions are available, then the set should be built according to the instructions to verify its accuracy and the selected source should be Instructions.

    Reliability rating: 3 (somewhat reliable).

  • Instructions - This source may be used for older sets which are difficult to locate in complete condition. Using this source means going through the entire instructions and inventorying all the parts shown to be used in the instructions.

    Reliability rating: 4 (moderately reliable).

  • Parts List - Parts lists may appear in the set instructions or printed on the set box. Official data showing set contents would also be considered a parts list. This source might not accurately reflect part variants.

    Reliability rating: 5 (highly reliable).

  • Sealed Bags / Open Box - This source should only be used when a new set is bought opened (seals broken), but all bags inside the box are present and still sealed. This source might not accurately reflect part variants that were not packed sealed (by factory). This source should not be used for sealed Polybags and Foilpacks.

    Reliability rating: 6 (highly reliable).

  • Sealed Set Contents - This source should only be used when a new, unopened set is first opened and its contents inventoried. Also to be used for sealed Polybags and Foilpacks.

    Reliability rating: 7 (most reliable).

  • Unknown - This identifier was added to older inventories when the option to select a source was not available. This option cannot be selected on the Add Inventory page, but it can be selected when editing pending inventories. Inventories will not be approved from an unknown source.
Step 3: Verify Parts
A red error message will appear if there is a problem with the entered data. The message will indicate the entry row number and the reason for the error. Click Go Back to return to the Add Inventory page and correct the error.

A warning message will be displayed below an item if there are any duplicate entries in the inventory. You may go back and correct the mistake or submit the inventory and then make the corrections on the Edit Pending Inventories Page.
