Plz tell me where to find agreement registration number?

If you cannot find the number like I myself couldn't because I received this Macbook from my college for my future classes then you should give AppleCare a call like again I myself did. They were able to confirm the serial number on my Macbook, take my personal information, register my Macbook, and now I'm good to go!! So calling AppleCare to get the situation sorted out is definitely the way to go. I waited a short minute to get connected but it was quick and easy after getting with connected with somebody at AppleCare and the guy was very,very friendly and courteous. Hope this helps!! Have a great day 🙂🙂🙂

This has absolutely nothing to do with Applecare. Please stop posting the same thing everywhere.

It specifically says to contact AppleCare when the "Agreement Registration Number" is wrong or not entered. I had this problem because I received a Macbook Pro from the college I attend and it does not show an "Agreement Registration Number" anywhere. So I called AppleCare to inquire about it and they kindly registered my Macbook for me. So I thought I would be helpful to some of the posts that have no answers to this question. At first, I didn't realize it was filtering by relevance so I switched the filter to most recent posts so that I could post this information. You don't have to be rude about it and I stand by my posts. If you are looking for your "Agreement Registration Number" and cannot find it then call AppleCare for assistance. They are very friendly and can help you get your Macbook or other Apple products registered.

1. There are other "enrollments" and "agreements" besides Applecare. This is one of them:

2. More importantly, you've been posting the exact same post in several threads - most of them 1 - 4 years old. Since any answer to any Applecare question after such a long time is utterly irrelevant because you can only purchase it within either 90 days or 364 days, your post can easily be construed as spamming. Hence, most of your posts have been removed.

It's wonderful that you want to help, but please try to answer a relatively newly posted question so your answer is actually relevant and may help.
