I'm planning to buy a new high-end macbook air and found that there're different part numbers for the same product: MD232LL/A and Z0ND0002Z. What is the difference between these two? Is it just about the released country or do they have different specs actually?

I appreciate your help in advance!

The two model numbers don't seem to refer to the exact same configuration. Model MD232LL/A appears to reference to the base model (as noted in Apple's MBA Model Identifier KB). The KB also notes:

If you have a custom configuration the Model Number and Configuration in the table may not match. Please use the Model Identifier to confirm the model of MacBook Air for custom configurations.

One example from Amazon - the specs include:

  • 1.8 GHz Intel Core i5 Processor
  • 256 GB Flash Storage
  • 4 GB DDR3 RAM

In the page from, the specs for model Z0ND0002Z include:

  • Core i7 2 GHz
  • 8 GB RAM
  • 512 GB HDD

It's probably that the Z0ND0002Z model is used by retailers that provide more customization, since Apple uses the MD232LL/A model in its online KB. The excerpt from the KB also supports this conclusion.

Thanks for the answer, JW8. I understand your point but I'm a little bit curious how multiple (unofficial) retailers use the same unauthorized model number Z0ND0002Z. My major concern is whether this model is an official customization or an uncertified illegal retrofit. I also wonder if there could be possibility (though small) of getting an unexpected product if I order this Z0ND0002Z model. Anyway your answer was very helpful. Thanks again! :) – K J Aug 1 '12 at 4:36
