You mentioned in your question the "uniqueness"aspect of  this desired part numbering system.  Other aspects could be there and may be in conflict with this "uniqueness" aspect.

  1. User friendly/Easy to remember aspect
  2. Significance/coding of part details in the part number
  3. Compatibility with external systems you use with external entites including suppliers, customs, shipping/clearing agents ..
  4. Regional/International considerations ... depending on the stretch of your business and supply chain in the world
  5. International standards and conventions governing the numbering of these parts

If you want the uniqueness aspect only, you may use your own (local) part numbers long enough part number to accommodate all the parts that you deal with now or may deal with in the future.   So, if you use8-digit number, than can accommodate up to100 Million numbers  !!  If you use6 digits , then that would be enough for1 mllion parts ...

 

If you want to code something in the part number, then this is another story, and if you want something easy to remember, that is also another story. and if you deal with manufacturers and suppliers from within and outside the country, then that would be yet a another story !!

 

So, what I am proposing here is that you design your part numbering system within the specifics and what applies to your taking the above considerations into account !!

To control unique item number assignment, companies need to establish rules of form, fit, and function:

1.       Form defines the configuration of an item, including factors such as geometric shape, size, density, weight, or other parameters that uniquely characterize that item.

2.       Fit is the ability of an item to physically interface or connect with or become an integral part of another item.

 

3.       Function defines the results that an item is expected to perform.

I think there is no concept behind it but there is some rules are there

 

1) Part no. should not start with Zero

2) Avoid using letter that is confused with number i.e., O,I

3) DO NOT use a manufacturer's serial number or part number for your part number. These numbers are often too long and cryptic. Plus, if you switch suppliers, or the manufacturer changes their number it becomes meaningless to your organization.

4) Use upto4 -8 characters will suffice.

5) Avoid loading inventory item descriptions with more information than absolutely necessary.

6) Do not use characters that might confuse people or software. For example, using a comma in   your item number might make it look like a quantity or price.

* Number length7-12 character

* Character set: Don't start the number with leading zero - use only numbers with no letters

* Stay with international standards

* Use encoding systems that are related to the products (health, books, ...)

Items number must be assigned to every new raw material to avoid confusions. Rules can be summarized are followed:

 

1-     Use unique item numbers: this requirement seems to be obvious but it is especially significant for engineering changes.

 

2-     Use only one set of item number within organization.

 

3-     Assign responsibility for creating items numbers.

 

4-     Do not reassign item numbers no longer in use.

 

5-     Use short item number.

 

6-     Keep items number uniform.

 

7-     Keep room for expansions.

 

8-     Avoid confusion characters such I and1,2 and Z, O and0

More often than not every spare part has their unique part number based on the diameters and weights etc. While Managing the inventory of spare parts one must be aware of the usage of the parts so that their serials can be mantained by their categories. If the store keeper is aware of the usage of the spares then he can manage the parts easily both physically and in system. There is also an issue of part numbrs being changed by the suppliers. Suggestion is that you keep the serial number based on the categories and do not create new item codes for all the new parts as they maybe changed part numbers with the same item. One needs to be on his toes all the times while dealing with the spare parts and their part numbers.
